PREFACE

This book is about leadership in organizations. Its primary focus is on managerial leadership as opposed to parliamentary leadership, leadership of social movements, or emergent leadership in informal groups. The book presents a broad survey of theory and research on leadership in for- mal organizations. Topics of special interest are the determinants of leadership effectiveness and how leadership can be improved.

In this 8th edition, the following improvements were made to make the book easier to un- derstand and more useful to most readers:

• Most chapters were revised for clarity and understanding (including Chapters 2 , 3 , 4 , 6 , 7 , 9 , 10 , 12 , 15 , and 16 ).

• The order of Chapters 4 to 12 was modified to improve explanation of related topics. • Several new examples of effective and ineffective leadership were added to Chapters 4 , 6 ,

11 , 13 , and 14 . • More practical guidelines for effective leadership were added to Chapters 3 , 6 , 7 , and 8 . • Several new examples were used in Chapters 3 , 11 , 12 , and 14 to explain how research is

conducted. • Over 100 citations to recent research were added throughout.

The basic structure of most chapters remains the same, but the order of some chapters was changed and a few topics were moved to a different chapter. Citations to relevant recent literature were updated, but given the increasing volume of studies on leadership, the citations are still selec- tive rather than comprehensive. Since the book is not intended to be a history of leadership, it seemed appropriate to reduce the amount of detail about early research programs and old theories that are no longer popular, and focus more closely on what we now know about effective leadership.

The content of the book still reflects a dual concern for theory and practice. I have attempted to satisfy two different audiences with somewhat different preferences. Most academics prefer a book that explains and evaluates major theories and relevant empirical research. They are more interested in how well the research was done, what was found, and what additional research is needed than in the practical applications. Academics tend to be skeptical about the value of pre- scriptions and guidelines for practitioners and consider them premature in the absence of further research. In contrast, most practitioners want some immediate answers about what to do and how to do it in order to be more effective as leaders. They need to deal with the current challenges of their job and cannot wait for decades until the academics resolve their theoretical disputes and ob- tain definitive answers. Practitioners are more interested in finding helpful remedies and prescrip- tions than in finding out how this knowledge was discovered. Readers who desire to improve their leadership effectiveness will find this edition of the book is even more useful than previous editions.

These different preferences are a one of the reasons for the much-lamented gulf between scientists and practitioners in management and industrial-organizational psychology. I believe it is important for managers and administrators to understand the complexity of effective leader- ship, the source of our knowledge about leadership in organizations, and the limitations of this knowledge. Likewise, I believe it is important for academics to think more about how their theories and research can be used to improve the practice of management. Too much of our leadership research is designed to examine narrow, esoteric questions that only interest a few other scholars who publish in the same journals.

xvi Preface

Academics will be pleased to find that major theories are explained and evaluated, findings in empirical research on leadership are summarized, and many references are provided to help readers find sources of additional information about topics of special interest. The field of lead- ership is still in a state of ferment, with many continuing controversies about conceptual and methodological issues. The book addresses these issues whenever feasible. However, the litera- ture review was intended to be incisive, not comprehensive. Rather than detailing an endless series of studies like most handbooks of leadership, the book describes major findings about ef- fective leadership. The current edition reflects significant progress in our understanding of lead- ership since the first edition was published in 1981.

For practitioners and students who desire to become effective managers, I attempted to convey a better appreciation of the complexity of managerial leadership, the importance of hav- ing theoretical knowledge about leadership, and the need to be flexible and pragmatic in applying this knowledge. The current edition provides many guidelines and recommendations for im- proving managerial effectiveness, but it is not a “practitioner’s manual” of simple techniques and secret recipes that guarantee instant success. The purpose of the guidelines is to help the reader understand the practical implications of the leadership theory and research, not to prescribe ex- actly how things must be done by a leader. Most of the guidelines are based on a limited amount of research and they are not infallible or relevant for all situations. Being a flexible, adaptive leader includes determining which guidelines are relevent for each unique situation.

Most chapters have one or two short cases designed to help the reader gain a better under- standing of the theories, concepts, and guidelines presented in the chapter. The cases describe events that occurred in real organizations, but some of the cases were modified to make them more useful for learning basic concepts and effective practices. For most of the cases, the names of organizations and individuals were changed to keep the analysis focused on the events that oc- curred in a defined time period, not on recent events that may involve different leaders and a new context. The cases ask a reader to analyze behavioral processes, identify examples of effective and ineffective behavior, and suggest effective ways to handle the situation that is depicted.

An instructor’s manual is available with detailed analyses of the cases and suggestions on how to use them. The instructor’s manual also includes additional cases, exercises for use in class (e.g., role plays), and some out-of-class activities that help students to understand how they can apply the theory and guidelines. Finally, a test bank is available with multiple-choice items on the major points in each chapter.

The book is widely used in many different countries, and some editions have been translated into other languages, including Chinese, Korean, Indonesian, Spanish, Greek, Croatian, and Swedish. With its focus on effective leadership in organizations, the book is especially relevant for people who expect to become a manager or administrator in the near future, for people who will be responsible for training or coaching leaders, and for people who will be teaching courses or work- shops that include leadership as one of the key topics. The book is appropriate for use as the primary text in an undergraduate or graduate course in leadership. Such courses are found in many different schools or departments, including business, psychology, sociology, educational administration, public administration, and health care administration. The book is on the list of required or recommended readings for students in many doctoral programs in leadership, management, and industrial- organizational psychology. Finally, the book is also useful for practicing managers and consultants who are looking for something more than superficial answers to difficult questions about leadership.

Learning Objectives After studying this chapter, you should be able to:

■ Understand the different ways leadership has been defined. ■ Understand the controversy about differences between leadership and management. ■ Understand why it is so difficult to assess leadership effectiveness. ■ Understand the different indicators used to assess leadership effectiveness. ■ Understand what aspects of leadership have been studied the most during the past 50 years. ■ Understand the organization of this book.

Leadership is a subject that has long excited interest among people. The term connotes images of powerful, dynamic individuals who command victorious armies, direct corporate empires from atop gleaming skyscrapers, or shape the course of nations. The exploits of brave and clever leaders are the essence of many legends and myths. Much of our description of history is the story of military, political, religious, and social leaders who are credited or blamed for important historical events, even though we do not understand very well how the events were caused or how much influence the leader really had. The widespread fascination with leadership may be because it is such a mysterious process, as well as one that touches everyone’s life. Why did certain leaders (e.g., Gandhi, Mohammed, Mao Tse-tung) inspire such intense fervor and dedi- cation? How did certain leaders (e.g., Julius Caesar, Alexander the Great) build great empires? Why did some rather undistinguished people (e.g., Adolf Hitler, Claudius Caesar) rise to posi- tions of great power? Why were certain leaders (e.g., Winston Churchill, Indira Gandhi) sud- denly deposed, despite their apparent power and record of successful accomplishments? Why do some leaders have loyal followers who are willing to sacrifice their lives, whereas other lead- ers are so despised that subordinates conspire to murder them?

Introduction: Th e Nature of Leadership

2 Chapter 1 • Introduction: The Nature of Leadership

Questions about leadership have long been a subject of speculation, but sci- entific research on leadership did not begin until the twentieth century. The focus of much of the research has been on the determinants of leadership effectiveness. Social scientists have attempted to discover what traits, abilities, behaviors, sources of power, or aspects of the situation determine how well a leader is able to influence followers and accomplish task objectives. There is also a growing interest in understanding leadership as a shared pro- cess in a team or organization and the reasons why this process is effective or ineffective. Other important questions include the reasons why some people emerge as leaders, and the determi- nants of a leader’s actions, but the predominant concern has been leadership effectiveness.

Some progress has been made in probing the mysteries surrounding leadership, but many questions remain unanswered. In this book, major theories and research findings on leader- ship effectiveness will be reviewed, with particular emphasis on managerial leadership in formal organizations such as business corporations, government agencies, hospitals, and universi- ties. This chapter introduces the subject by considering different conceptions of leadership, dif- ferent ways of evaluating its effectiveness, and different approaches for studying leadership. The chapter also provides an overview of the book and explains how subjects are organized.

Definitions of Leadership

The term leadership is a word taken from the common vocabulary and incorporated into the technical vocabulary of a scientific discipline without being precisely redefined. As a consequence, it carries extraneous connotations that create ambiguity of meaning (Janda, 1960). Additional confusion is caused by the use of other imprecise terms such as power , author- ity , management , administration , control , and supervision to describe similar phenomena. An observation by Bennis (1959, p. 259) is as true today as when he made it many years ago:

Always, it seems, the concept of leadership eludes us or turns up in another form to taunt us again with its slipperiness and complexity. So we have invented an endless proliferation of terms to deal with it . . . and still the concept is not sufficiently defined.

Researchers usually define leadership according to their individual perspectives and the as- pects of the phenomenon of most interest to them. After a comprehensive review of the leadership literature, Stogdill (1974, p. 259) concluded that “there are almost as many definitions of leadership as there are persons who have attempted to define the concept.” The stream of new definitions has continued unabated since Stogdill made his observation. Leadership has been defined in terms of traits, behaviors, influence, interaction patterns, role relationships, and occupation of an adminis- trative position. Table 1-1 shows some representative definitions presented over the past 50 years.

Most definitions of leadership reflect the assumption that it involves a process whereby in- tentional influence is exerted over other people to guide, structure, and facilitate activities and rela- tionships in a group or organization. The numerous definitions of leadership appear to have little else in common. They differ in many respects, including who exerts influence, the intended pur- pose of the influence, the manner in which influence is exerted, and the outcome of the influence attempt. The differences are not just a case of scholarly nit-picking; they reflect deep disagreement about identification of leaders and leadership processes. Researchers who differ in their concep- tion of leadership select different phenomena to investigate and interpret the results in different ways. Researchers who have a very narrow definition of leadership are less likely to discover things that are unrelated to or inconsistent with their initial assumptions about effective leadership.

Chapter 1 • Introduction: The Nature of Leadership 3

Because leadership has so many different meanings to people, some theorists question whether it is even useful as a scientific construct (e.g., Alvesson & Sveningsson, 2003; Miner, 1975). Nevertheless, most behavioral scientists and practitioners seem to believe leadership is a real phenomenon that is important for the effectiveness of organizations. Interest in the subject con- tinues to increase, and the deluge of articles and books about leadership shows no sign of abating.

Specialized Role or Shared Influence Process?

A major controversy involves the issue of whether leadership should be viewed as a special- ized role or as a shared influence process. One view is that all groups have role specialization, and the leadership role has responsibilities and functions that cannot be shared too widely without jeopardizing the effectiveness of the group. The person with primary responsibility to perform the specialized leadership role is designated as the “leader.” Other members are called “followers” even though some of them may assist the primary leader in carrying out leadership functions. The distinction between leader and follower roles does not mean that a person cannot perform both roles at the same time. For example, a department manager who is the leader of department employees is also a follower of higher-level managers in the organization. Researchers who view leadership as a specialized role are likely to pay more attention to the attributes that determine selection of designated leaders, the typical behavior of designated leaders, and the effects of this behavior on other members of the group or organization.

Another way to view leadership is in terms of an influence process that occurs naturally within a social system and is diffused among the members. Writers with this perspective believe it is more useful to study “leadership” as a social process or pattern of relationships rather than as a specialized role. According to this view, various leadership functions may be carried out by dif- ferent people who influence what the group does, how it is done, and the way people in the group relate to each other. Leadership may be exhibited both by formally selected leaders and by infor- mal leaders. Important decisions about what to do and how to do it are made through the use of an interactive process involving many different people who influence each other. Researchers who view leadership as a shared, diffuse process, are likely to pay more attention to the complex

TABLE 1-1 Definitions of Leadership • Leadership is “the behavior of an individual . . . directing the activities of a group toward a

shared goal” (Hemphill & Coons, 1957, p. 7). • Leadership is “the influential increment over and above mechanical compliance with the

routine directives of the organization” (Katz & Kahn, 1978, p. 528). • Leadership is “the process of influencing the activities of an organized group toward goal

achievement” (Rauch & Behling, 1984, p. 46). • “Leadership is about articulating visions, embodying values, and creating the environment

within which things can be accomplished” (Richards & Engle, 1986, p. 206). • “Leadership is a process of giving purpose (meaningful direction) to collective effort, and

causing willing effort to be expended to achieve purpose” (Jacobs & Jaques, 1990, p. 281). • Leadership “is the ability to step outside the culture . . . to start evolutionary change processes

that are more adaptive” (Schein, 1992, p. 2). • “Leadership is the process of making sense of what people are doing together so that people

will understand and be committed” (Drath & Palus, 1994, p. 4). • Leadership is “the ability of an individual to influence, motivate, and enable others to contribute

toward the effectiveness and success of the organization . . .” (House et al., 1999, p. 184).

4 Chapter 1 • Introduction: The Nature of Leadership

influence processes that occur among members, the context and conditions that determine when and how they occur, the processes involved in the emergence of informal leaders, and the conse- quences for the group or organization.

Type of Influence Process

Controversy about the definition of leadership involves not only who exercises influence, but also what type of influence is exercised and the outcome. Some theorists would limit the definition of leadership to the exercise of influence resulting in enthusiastic commitment by fol- lowers, as opposed to indifferent compliance or reluctant obedience. These theorists argue that the use of control over rewards and punishments to manipulate or coerce followers is not really “leading” and may involve the unethical use of power.

An opposing view is that this definition is too restrictive because it excludes some influ- ence processes that are important for understanding why a leader is effective or ineffective in a given situation. How leadership is defined should not predetermine the answer to the research question of what makes a leader effective. The same outcome can be accomplished with differ- ent influence methods, and the same type of influence attempt can result in different outcomes, depending on the nature of the situation. Even people who are forced or manipulated into doing something may become committed to it if they subsequently discover that it really is the best op- tion for them and the organization. The ethical use of power is a legitimate concern for leader- ship scholars, but it should not limit the definition of leadership or the type of influence processes that are studied.

Purpose of Influence Attempts

Another controversy about which influence attempts are part of leadership involves their purpose and outcome. One viewpoint is that leadership occurs only when people are influenced to do what is ethical and beneficial for the organization and themselves. This definition of lead- ership does not include influence attempts that are irrelevant or detrimental to followers, such as a leader’s attempts to gain personal benefits at the follower’s expense.

An opposing view would include all attempts to influence the attitudes and behavior of fol- lowers in an organizational context, regardless of the intended purpose or actual beneficiary. Acts of leadership often have multiple motives, and it is seldom possible to determine the extent to which they are selfless rather than selfish. The outcomes of leader actions usually include a mix of costs and benefits, some of which are unintended, making it difficult to infer purpose. Despite good intentions, the actions of a leader are sometimes more detrimental than beneficial for fol- lowers. Conversely, actions motivated solely by a leader’s personal needs sometimes result in un- intended benefits for followers and the organization. Thus, the domain of leadership processes to study should not be limited by the leader’s intended purpose.

Influence Based on Reason or Emotions

Most of the leadership definitions listed earlier emphasize rational, cognitive processes. For many years, it was common to view leadership as a process wherein leaders influence followers to believe it is in their best interest to cooperate in achieving a shared task objective. Until the 1980s, few conceptions of leadership recognized the importance of emotions as a basis for influence.

In contrast, some recent conceptions of leadership emphasize the emotional aspects of in- fluence much more than reason. According to this view, only the emotional, value-based aspects of leadership influence can account for the exceptional achievements of groups and organizations.

Chapter 1 • Introduction: The Nature of Leadership 5

Leaders inspire followers to willingly sacrifice their selfish interests for a higher cause. For exam- ple, leaders can motivate soldiers to risk their lives for an important mission or to protect their comrades. The relative importance of rational and emotional processes and how they interact are issues to be resolved by empirical research, and the conceptualization of leadership should not exclude either type of process.

Direct and Indirect Leadership

Most theories about effective leadership focus on behaviors used to directly influence immediate subordinates, but a leader can also influence other people inside the organization, including peers, bosses, and people at lower levels who do not report to the leader. Some theo- rists make a distinction between direct and indirect forms of leadership to help explain how a leader can influence people when there is no direct interaction with them (Hunt, 1991; Lord & Maher, 1991; Yammarino, 1994).

A chief executive officer (CEO) has many ways to influence people at lower levels in the or- ganization. Direct forms of leadership involve attempts to influence followers when interacting with them or using communication media to send messages to them. Examples include send- ing memos or reports to employees, sending e-mail messages, presenting speeches on television, holding meetings with small groups of employees, and participating in activities involving em- ployees (e.g., attending orientation or training sessions, company picnics). Most of these forms of influence can be classified as direct leadership.

Indirect leadership has been used to describe how a chief executive can influence people at lower levels in the organization who do not interact directly with the leader (Bass, Waldman, Avolio, & Bebb, 1987; Waldman & Yammarino, 1999; Yammarino, 1994). One form of indirect leadership by a CEO is called “cascading.” It occurs when the direct influence of the CEO is trans- mitted down the authority hierarchy of an organization from the CEO to middle managers, to lower- level managers, to regular employees. The influence can involve changes in employee attitudes, beliefs, values, or behaviors. For example, a CEO who sets a good example of ethical and sup- portive behavior may influence similar behavior by employees at lower levels in the organization.

Another form of indirect leadership involves influence over formal programs, management systems, and structural forms (Hunt, 1991; Lord & Maher, 1991; Yukl & Lepsinger, 2004). Many large organizations have programs or management systems intended to influence the attitudes, skills, behavior, and performance of employees. Examples include programs for recruitment, selection, and promotion of employees. Structural forms and various types of programs can be used to increase control, coordination, efficiency, and innovation. Examples include formal rules and procedures, specialized subunits, decentralized product divisions, standardized facilities, and self-managed teams. In most organizations only top executives have sufficient authority to im- plement new programs or change the structural forms (see Chapter 11 ).

A third form of indirect leadership involves leader influence over the organization cul- ture, which is defined as the shared beliefs and values of members (Schein, 1992; Trice & Beyer, 1991). Leaders may attempt either to strengthen existing cultural beliefs and values or to change them. There are many ways for leaders to influence an organization’s culture. Some ways involve direct influence (e.g., communicating a compelling vision or leading by example), and some in- volve forms of indirect influence, such as changing the organizational structure, reward systems, and management programs (see Chapter 11 ). For example, a CEO can implement programs to re- cruit, select, and promote people who share the same values (Giberson, Resick, & Dickson, 2005).

The interest in indirect leadership is useful to remind scholars that leadership influence is not limited to the types of observable behavior emphasized in many leadership theories. However,

6 Chapter 1 • Introduction: The Nature of Leadership

it is important to remember that a simple dichotomy does not capture the complexity involved in these influence processes. Some forms of influence are not easily classified as either direct or indirect leadership. Moreover, direct and indirect forms of influence are not mutually exclusive, and when used together in a consistent way, it is possible to magnify their effects (see Chapter 11 ).

There is a continuing controversy about the difference between leadership and manage- ment. It is obvious that a person can be a leader without being a manager (e.g., an informal leader), and a person can be a manager without leading. Indeed, some people with the job title “manager” do not have any subordinates (e.g., a manager of financial accounts). Nobody has proposed that managing and leading are equivalent, but the degree of overlap is a point of sharp disagreement.

Some writers contend that leadership and management are qualitatively different and mutu- ally exclusive (e.g., Bennis & Nanus, 1985; Zaleznik, 1977). The most extreme distinction assumes that management and leadership cannot occur in the same person. For these writers, leaders and managers differ with regard to their values and personalities. Managers value stability, order, and ef- ficiency, and they are impersonal, risk-averse, and focused on short-term results. Leaders value flex- ibility, innovation, and adaptation; they care about people as well as economic outcomes, and they have a longer-term perspective with regard to objectives and strategies. Managers are concerned about how things get done, and they try to get people to perform better. Leaders are concerned with what things mean to people, and they try to get people to agree about the most important things to be done. Bennis and Nanus (1985, p. 21) proposed that “managers are people who do things right, and leaders are people who do the right thing.” However, the empirical research does not support the assumption that people can be sorted neatly into these two extreme stereotypes. Moreover, the stereotypes imply that managers are generally ineffective. The term manager is an occupational title for a large number of people, and it is insensitive to denigrate them with a negative stereotype.

Other scholars view leading and managing as distinct processes or roles, but they do not as- sume that leaders and managers are different types of people (Bass, 1990; Hickman, 1990; Kotter, 1988; Mintzberg, 1973; Rost, 1991). How the two processes are defined varies somewhat, de- pending on the scholar. For example, Mintzberg (1973) described leadership as one of the 10 managerial roles (see Chapter 2 ). Leadership includes motivating subordinates and creating fa- vorable conditions for doing the work. The other nine roles (e.g., resource allocator, negotiator) involve distinct managing responsibilities, but leadership is viewed as an essential managerial role that pervades the other roles.

Kotter (1990) proposed that managing seeks to produce predictability and order, where- as leading seeks to produce organizational change. Both roles are necessary, but problems can occur if an appropriate balance is not maintained. Too much emphasis on the managing role can discourage risk taking and create a bureaucracy without a clear purpose. Too much emphasis on the leadership role can disrupt order and create change that is impractical. According to Kotter, the importance of leading and managing depends in part on the situation. As an organization becomes larger and more complex, managing becomes more important. As the external envi- ronment becomes more dynamic and uncertain, leadership becomes more important. Both roles are important for executives in large organizations with a dynamic environment. When Kotter surveyed major large companies in a dynamic environment, he found very few had executives who were able to carry out both roles effectively.

Rost (1991) defined management as an authority relationship that exists between a man- ager and subordinates to produce and sell goods and services. He defined leadership as a

Chapter 1 • Introduction: The Nature of Leadership 7

multidirectional influence relationship between a leader and followers with the mutual purpose of accomplishing real change. Leaders and followers influence each other as they interact in non- coercive ways to decide what changes they want to make. Managers may be leaders, but only if they have this type of influence relationship. Rost proposed that leading was not necessary for a manager to be effective in producing and selling goods and services. However, leading is essen- tial when major changes must be implemented in an organization, because authority is seldom a sufficient basis for gaining commitment from subordinates or for influencing other people whose cooperation is necessary, such as peers and outsiders.

Defining managing and leading as distinct roles, processes, or relationships may obscure more than it reveals if it encourages simplistic theories about effective leadership. Most scholars seem to agree that success as a manager or administrator in modern organizations also involves leading. How to integrate the two processes has emerged as a complex and important issue in organizational literature (Yukl & Lepsinger, 2005). The answer will not come from debates about ideal definitions. Questions about what to include in the domain of essential leadership pro- cesses should be explored with empirical research, not predetermined by subjective judgments.

A Working Definition of Key Terms

It is neither feasible nor desirable at this point in the development of the discipline to attempt to resolve the controversies over the appropriate definition of leadership. Like all con- structs in social science, the definition of leadership is arbitrary and subjective. Some definitions are more useful than others, but there is no single “correct” definition that captures the essence of leadership. For the time being, it is better to use the various conceptions of leadership as a source of different perspectives on a complex, multifaceted phenomenon.

In research, the operational definition of leadership depends to a great extent on the pur- pose of the researcher (Campbell, 1977). The purpose may be to identify leaders, to determine how they are selected, to discover what they do, to discover why they are effective, or to deter- mine whether they are necessary. As Karmel (1978, p. 476) notes, “It is consequently very dif- ficult to settle on a single definition of leadership that is general enough to accommodate these many meanings and specific enough to serve as an operationalization of the variable.” Whenever feasible, leadership research should be designed to provide information relevant to a wide range of definitions, so that over time it will be possible to compare the utility of different conceptions and arrive at some consensus on the matter.

In this book, leadership is defined broadly in a way that takes into account several things that determine the success of a collective effort by members of a group or organization to accom- plish meaningful tasks. The following definition is used:

Leadership is the process of influencing others to understand and agree about what needs to be done and how to do it, and the process of facilitating individual and collective efforts to accomplish shared objectives.

The definition includes efforts not only to influence and facilitate the current work of the group or organization, but also to ensure that it is prepared to meet future challenges. Both di- rect and indirect forms of influence are included. The influence process may involve only a sin- gle leader or it may involve many leaders. Table 1-2 shows the wide variety of ways leaders can influence the effectiveness of a group or organization.

In this book, leadership is treated as both a specialized role and a social influence process. More than one individual can perform the role (i.e., leadership can be shared or distributed), but

8 Chapter 1 • Introduction: The Nature of Leadership

some role differentiation is assumed to occur in any group or organization. Both rational and emo- tional processes are viewed as essential aspects of leadership. No assumptions are made about the actual outcome of the influence processes, because the evaluation of outcomes is difficult and sub- jective. Thus, the definition of leadership is not limited to processes that necessarily result in “suc- cessful” outcomes. How leadership processes affect outcomes is a central research question that should not be biased by the definition of leadership. The focus is clearly on the process, not the per- son, and they are not assumed to be equivalent. Thus, the terms leader , manager , and boss are used interchangeably in this book to indicate people who occupy positions in which they are expected to perform the leadership role, but without any assumptions about their actual behavior or success.

The terms subordinate and direct report are used interchangeably to denote someone whose primary work activities are directed and evaluated by the focal leader. Some writers use the term staff as a substitute for subordinate, but this practice creates unnecessary confusion. The term con- notes a special type of advisory position, and most subordinates are not staff advisors. Moreover, the term staff is used both as a singular and plural noun, which creates a lot of unnecessary con- fusion. The term associate has become popular in business organizations as another substitute for subordinate, because it conveys a relationship in which employees are valued and supposedly empowered. However, this vague term fails to differentiate between a direct authority relationship and other types of formal relationships (e.g., peers, partners). To clarify communication, this text continues to use the term subordinate to denote the existence of a formal authority relationship.

The term follower is used to describe a person who acknowledges the focal leader as the primary source of guidance about the work, regardless of how much formal authority the leader actually has over the person. Unlike the term subordinate , the term follower does not pre- clude leadership processes that can occur even in the absence of a formal authority relation- ship. Followers may include people who are not direct reports (e.g., coworkers, team members, partners, outsiders). However, the term follower is not used to describe members of an organi- zation who completely reject the formal leader and seek to remove the person from office; such people are more appropriately called “rebels” or “insurgents.”

Indicators of Leadership Effectiveness Like definitions of leadership, conceptions of leader effectiveness differ from one writer to

another. The criteria selected to evaluate leadership effectiveness reflect a researcher’s explicit or implicit conception of leadership. Most researchers evaluate leadership effectiveness in terms of the consequences of influence on a single individual, a team or group, or an organization.

TABLE 1-2 What Leaders Can Influence

• The choice of objectives and strategies to pursue. • The motivation of members to achieve the objectives. • The mutual trust and cooperation of members. • The organization and coordination of work activities. • The allocation of resources to activities and objectives. • The development of member skills and confidence. • The learning and sharing of new knowledge by members. • The enlistment of support and cooperation from outsiders. • The design of formal structure, programs, and systems. • The shared beliefs and values of members.

Chapter 1 • Introduction: The Nature of Leadership 9

One very relevant indicator of leadership effectiveness is the extent to which the perfor- mance of the team or organization is enhanced and the attainment of goals is facilitated (Bass, 2008; Kaiser, Hogan & Craig, 2008). Examples of objective measures of performance include sales, net profits, profit margin, market share, return on investment, return on assets, productiv- ity, cost per unit of output, costs in relation to budgeted expenditures, and change in the value of corporate stock. Subjective measures of effectiveness include ratings obtained from the leader’s superiors, peers, or subordinates.

Follower attitudes and perceptions of the leader are another common indicator of leader effectiveness, and they are usually measured with questionnaires or interviews. How well does the leader satisfy the needs and expectations of followers? Do they like, respect, and admire the leader? Do they trust the leader and perceive him or her to have high integrity? Are they strongly committed to carrying out the leader’s requests, or will they resist, ignore, or subvert them? Does the leader improve the quality of work life, build the self-confidence of followers, increase their skills, and contribute to their psychological growth and development? Follower attitudes, percep- tions, and beliefs also provide an indirect indicator of dissatisfaction and hostility toward the leader. Examples of such indicators include absenteeism, voluntary turnover, grievances, com- plaints to higher management, requests for transfer, work slowdowns, and deliberate sabotage of equipment and facilities.

Leader effectiveness is occasionally measured in terms of the leader’s contribution to the quality of group processes, as perceived by followers or by outside observers. Does the leader en- hance group cohesiveness, member cooperation, member commitment, and member confidence that the group can achieve its objectives? Does the leader enhance problem solving and decision making by the group, and help to resolve disagreements and conflicts in a constructive way? Does the leader contribute to the efficiency of role specialization, the organization of activities, the ac- cumulation of resources, and the readiness of the group to deal with change and crises?

A final type of criterion for leadership effectiveness is the extent to which a person has a successful career as a leader. Is the person promoted rapidly to positions of higher authority? Does the person serve a full term in a leadership position, or is he or she removed or forced to resign? For elected positions in organizations, is a leader who seeks reelection successful?

It is difficult to evaluate the effectiveness of a leader when there are so many alternative measures of effectiveness, and it is not clear which measure is most relevant. Some research- ers attempt to combine several measures into a single, composite criterion, but this approach requires subjective judgments about how to assign a weight to each measure. Multiple criteria are especially troublesome when they are negatively correlated. A negative correlation means that trade-offs occur among criteria, such that as one increases, others decrease. For example, increasing sales and market share (e.g., by reducing price and increasing advertising) may result in lower profits. Likewise, an increase in production output (e.g., by inducing people to work faster) may reduce product quality or employee satisfaction.

Immediate and Delayed Outcomes

Some outcomes are more immediate than others. For example, the immediate result of an influence attempt is whether followers are willing to do what the leader asks, but a delayed effect is how well followers actually perform the assignment. The effects of a leader can be viewed as a causal chain of variables, with each “mediating variable” explaining the effects of the preceding one on the next one. An example is provided in Figure 1-1 . The farther along in the causal chain, the longer it takes for the effect to occur. For criteria at the end of the causal chain, there is a con- siderable delay (months or years) before the effects of the leader’s actions are evident. Moreover,

10 Chapter 1 • Introduction: The Nature of Leadership

these end-result criteria are more likely to be influenced by extraneous events (e.g., the economy, market conditions). When the delay is long and there is considerable “contamination” of end- result criteria by extraneous events, then these criteria may be less useful for assessing leadership effectiveness than more immediate outcomes.

In many cases, a leader has both immediate and delayed effects on the same criterion. The two types of effects may be consistent or inconsistent. When they are inconsistent, the imme- diate outcome may be very different from the delayed outcomes. For example, profits may be increased in the short run by eliminating costly activities that have a delayed effect on profits, such as equipment maintenance, research and development, investments in new technology, and employee skill training. In the long run, the net effect of cutting these essential activities is likely to be lower profits because the negative consequences slowly increase and eventually outweigh any benefits. The converse is also true: increased investment in these activities is likely to reduce immediate profits but increase long-term profits.

What Criteria to Use?

There is no simple answer to the question of how to evaluate leadership effectiveness. The selection of appropriate criteria depends on the objectives and values of the person making the evaluation, and people have different values. For example, top management may prefer different criteria than other employees, customers, or shareholders. To cope with the problems of incompat- ible criteria, delayed effects, and the preferences of different stakeholders, it is usually best to include a variety of criteria in research on leadership effectiveness and to examine the impact of the leader on each criterion over an extended period of time. Multiple conceptions of effectiveness, like mul- tiple conceptions of leadership, serve to broaden our perspective and enlarge the scope of inquiry.

Major Perspectives in Leadership Theory and Research The attraction of leadership as a subject of research and the many different conceptions

of leadership have created a vast and bewildering literature. Attempts to organize the literature according to major approaches or perspectives show only partial success. One of the more use- ful ways to classify leadership theory and research is according to the type of variable that is emphasized the most. Three types of variables that are relevant for understanding leadership effectiveness include (1) characteristics of leaders, (2) characteristics of followers, and (3) charac- teristics of the situation. Examples of key variables within each category are shown in Table 1-3 . Figure 1-2 depicts likely causal relationships among the variables.

FIGURE 1-2 Causal Relationships Among the Primary Types of Leadership Variables

Most leadership theories emphasize one category more than the others as the primary basis for explaining effective leadership, and leader characteristics have been emphasized most often over the past half-century. Another common practice is to limit the focus to one type of leader characteristic, namely traits, behavior, or power. To be consistent with most of the leader- ship literature, the theories and empirical research reviewed in this book are classified into the

12 Chapter 1 • Introduction: The Nature of Leadership

following five approaches: (1) the trait approach, (2) the behavior approach, (3) the power-influ- ence approach, (4) the situational approach, and (5) the integrative approach. Each approach is described briefly in the following sections.

Trait Approach

One of the earliest approaches for studying leadership was the trait approach. This approach emphasizes attributes of leaders such as personality, motives, values, and skills. Underlying this approach was the assumption that some people are natural leaders, endowed with certain traits not possessed by other people. Early leadership theories attrib- uted managerial success to extraordinary abilities such as tireless energy, penetrating intuition, uncanny foresight, and irresistible persuasive powers. Hundreds of trait studies conducted during the 1930s and 1940s sought to discover these elusive qualities, but this massive research effort failed to find any traits that would guarantee leadership success. One reason for the failure was a lack of attention to mediating variables in the causal chain that could explain how traits could affect a delayed outcome such as group performance or leader advancement. The predominant research method was to look for a significant correlation between individual leader attributes and a criterion of leader success, without examining any explanatory pro- cesses. However, as evidence from better designed research slowly accumulated over the years, researchers made progress in discovering how leader attributes are related to leadership behav- ior and effectiveness. A more recent trait approach examines leader values that are relevant for explaining ethical leadership.

Behavior Approach

The behavior approach began in the early 1950s after many researchers became discour- aged with the trait approach and began to pay closer attention to what managers actually do on the job. One line of research examines how managers spend their time and the typical pat- tern of activities, responsibilities, and functions for managerial jobs. Some of the research also investigates how managers cope with demands, constraints, and role conflicts in their jobs. Most research on managerial work uses descriptive methods of data collection such as direct observation, diaries, job description questionnaires, and anecdotes obtained from inter- views. Although this research was not designed to directly assess effective leadership, it provides useful insights into this subject. Leadership effectiveness depends in part on how well a manager resolves role conflicts, copes with demands, recognizes opportunities, and overcomes constraints.

Another subcategory of the behavior approach focuses on identifying leader ac- tions or decisions with observable aspects and relating them to indicators of effective leader- ship. The preferred research method involves a survey field study with a behavior description questionnaire. In the past 50 years, hundreds of survey studies examined the correlation between leadership behavior and various indicators of leadership effectiveness. A much smaller number of studies used laboratory experiments, field experiments, or critical incidents to determine how effective leaders differ in behavior from ineffective leaders.

Power-Influence Approach

Power-influence research examines influence processes between leaders and other people. Like most research on traits and behavior, some of the power-influence research takes a leader-centered perspective with an implicit assumption that causality is unidirectional (leaders

Chapter 1 • Introduction: The Nature of Leadership 13

act and followers react). This research seeks to explain leadership effectiveness in terms of the amount and type of power possessed by a leader and how power is exercised. Power is viewed as important not only for influencing subordinates, but also for influencing peers, superiors, and people outside the organization, such as clients and suppliers. The favorite methodology has been the use of survey questionnaires to relate leader power to various measures of leadership effectiveness.

Other power-influence research used questionnaires and descriptive incidents to determine how leaders influence the attitudes and behavior of followers. The study of influence tactics can be viewed as a bridge linking the power-influence approach and the behavior approach. The use of different influence tactics is compared in terms of their relative effectiveness for getting people to do what the leader wants.

Participative leadership is concerned with power sharing and empowerment of followers, but it is firmly rooted in the tradition of behavior research as well. Many studies used question- naires to correlate subordinate perceptions of participative leadership with the criteria of leader- ship effectiveness such as subordinate satisfaction, effort, and performance. Laboratory and field experiments compared autocratic and participative leadership styles. Finally, descriptive case studies of effective managers examined how they use consultation and delegation to give people a sense of ownership for decisions.

Situational Approach

The situational approach emphasizes the importance of contextual factors that influence leadership processes. Major situational variables include the characteristics of followers, the nature of the work performed by the leader’s unit, the type of organization, and the nature of the external environment. This approach has two major subcategories. One line of research is an attempt to discover the extent to which leadership processes are the same or unique across different types of organizations, levels of management, and cultures. The primary research method is a comparative study of two or more situations. The dependent variables may be managerial perceptions and attitudes, managerial activities and behavior patterns, or influence processes.

The other subcategory of situational research attempts to identify aspects of the situation that “moderate” the relationship of leader attributes (e.g., traits, skills, behavior) to leadership ef- fectiveness. The assumption is that different attributes will be effective in different situations, and that the same attribute is not optimal in all situations. Theories describing this relationship are sometimes called “contingency theories” of leadership. A more extreme form of situational theory (“leadership substitutes”) identifies the conditions that can make hierarchical leadership redundant and unnecessary.

Integrative Approach

An integrative approach involves more than one type of leadership variable. In recent years, it has become more common for researchers to include two or more types of leadership variables in the same study, but it is still rare to find a theory that includes all of them (i.e., traits, behavior, influence processes, situational variables, and outcomes). An example of the integra- tive approach is the self-concept theory of charismatic leadership, which attempts to explain why the followers of some leaders are willing to exert exceptional effort and make personal sacrifices to accomplish the group objective or mission.

14 Chapter 1 • Introduction: The Nature of Leadership

Level of Conceptualization for Leadership Theories Another way to classify leadership theories is in terms of the “level of conceptualiza-

tion” or type of constructs used to describe leaders and their influence on others. Leadership can be described as (1) an intra-individual process, (2) a dyadic process, (3) a group process, or (4) an organizational process. The levels can be viewed as a hierarchy, as depicted in Figure 1-3 . What level is emphasized will depend on the primary research question, the type of criterion vari- ables used to evaluate leadership effectiveness, and the type of mediating processes used to explain leadership influence. Typical research questions for each level are listed in Table 1-4 . The four levels of conceptualization, and their relative advantages and disadvantages, are described next.

Intra-Individual Processes

Because most definitions of leadership involve influence processes between individu- als, leadership theories that describe only leader attributes are rare. Nevertheless, a number of researchers used psychological theories of personality traits, values, skills, motivation, and cogni- tion to explain the decisions and behavior of an individual leader. Roles, behaviors, or decision styles are also used for describing and comparing leaders. Examples can be found in theories about the nature of managerial work and the requirements for different types of leadership posi- tions (see Chapter 2 ). Individual traits and skills are also used to explain a person’s motivation to seek power and positions of authority (see Chapter 6 ), and individual values are used to explain ethical leadership and the altruistic use of power (see Chapter 13 ).

Knowledge of intra-individual processes and taxonomies of leadership roles, behaviors, and traits provide insights that are helpful for developing better theories of effective leader- ship. However, the potential contribution of the intra-individual approach to leadership is lim- ited, because it does not explicitly include what most theorists consider to be the essential process of leadership, namely influencing others such as subordinates, peers, bosses, and outsiders.

Dyadic Processes

The dyadic approach focuses on the relationship between a leader and another individual who is usually a subordinate or another type of follower. The need to influence direct reports is shared by leaders at all levels of authority from chief executives to department managers

and work crew supervisors. The explanation of leader influence is usually in terms of how the leader causes the subordinate to be more motivated and more capable of accomplishing task assignments. These theories usually focus on leadership behavior as the source of influence, and on changes in the attitudes, motivation, and behavior of an individual subordinate as the influence process. Reciprocal influence between the leader and follower may be included in the theory, but it is usually less important than the explanation of leader influence over the follower.

16 Chapter 1 • Introduction: The Nature of Leadership

An example of a dyadic leadership theory is the leader-member exchange (LMX) theory described in Chapter 9 , which describes how dyadic relationships evolve over time and take dif- ferent forms, ranging from a casual exchange to a cooperative alliance with shared objectives and mutual trust. Although the LMX theory recognizes that the leader has multiple dyadic relation- ships, the focus is clearly on what happens within a single relationship. Much of the research on power and influence tactics (see Chapter 8 ) is also conceptualized in terms of dyadic processes. Most theories of transformational and charismatic leadership were initially conceptualized primarily at the dyadic level (see Chapter 12 ).

Since real leaders seldom have only a single subordinate, some assumptions are necessary to make dyadic explanations relevant for explaining a leader’s influence on the performance of a group or work unit. One assumption is that subordinates have work roles that are similar and independent. Subordinates may not be homogeneous with regard to skills and motives, but they have similar jobs. There is little potential for subordinates to affect each other’s job performance, and group performance is the sum of the performances by individuals. An example of mini- mum interdependence is a district sales unit in which sales representatives work separately and independently of each other and sell the same product in different locations or to different cus- tomers. However, when there is high interdependence among group members, a high need for collective learning, and strong external dependencies, a group-level theory is needed to explain how leadership can influence group performance.

The dyadic theories do not include some leadership behaviors that are necessary to facili- tate collective performance by a team or organization. Moreover, some of the dyadic behaviors that are effective in terms of dyadic influence will be ineffective with regard to team perfor- mance or organizational performance. For example, attempts to develop a closer relationship with one subordinate (e.g., by providing more benefits) may be dysfunctional if they create per- ceptions of inequity by other subordinates. Efforts to empower individual subordinates may create problems when it is necessary to have a high degree of coordination among all of the subordinates. The extra time needed by a leader to maximize performance by an individual subordinate (e.g., providing intensive coaching) may be more effectively used to deal with prob- lems that involve the team or work group (e.g., obtaining necessary resources, facilitating coop- eration and coordination).

Another limitation of most dyadic theories is inadequate attention to the context. In most dyadic theories of effective leadership, aspects of the situation are likely to be treated as modera- tor variables that constrain or enhance leader influence on individual subordinates. The dyadic theories underestimate the importance of the context for determining what type of leadership is necessary to enhance collective performance by multiple subordinates.

Group Processes

When effective leadership is viewed from a group-level perspective, the focus is on the influence of leaders on collective processes that determine team performance. The explanatory influence processes include determinants of group effectiveness that can be influenced by leaders, and they usually involve all members of a group or team, not only a single subordinate. Examples of these collective explanatory processes include how well the work is organized to utilize per- sonnel and resources, how committed members are to perform their work roles effectively, how confident members are that the task can be accomplished successfully (“potency”), and the extent to which members trust each other and cooperate in accomplishing task objectives. The leader- ship behaviors identified in dyadic theories are still relevant for leadership in teams, but other behaviors are also important.

Chapter 1 • Introduction: The Nature of Leadership 17

Behavioral theories describing leadership processes in various types of groups and teams are discussed in Chapter 10 , and leadership in executive teams is discussed in Chapter 11 . Much of a manager’s time is spent in formal and informal meetings, and the leadership processes that make group meetings more effective are also described in Chapter 10 . Another key research question in the group approach is to explain why some members are more influential than others, and how leaders are selected. An example of a theory dealing with these questions is the “social exchange theory” discussed in Chapter 8 .

As compared to the dyadic theories, most group-level theories provide a much better ex- planation of effective leadership in teams with interactive members, but these theories also have limitations. The need to describe leader influence on member motivation is usually recognized, but the theory may not include psychological processes that are useful for explaining this influ- ence. The need to influence people and processes outside of the team is usually recognized, but external relationships are usually viewed from the perspective of the team. The focus is on the efforts of leaders to improve team performance (e.g., by getting more resources), but the impli- cations of leader actions for other subunits or the larger organization are seldom explicitly con- sidered. Shared leadership is more likely to be included in a group-level theory than in a dyadic theory, but distributed leadership by multiple formal leaders is seldom explicitly included, even though it is common in some types of teams (e.g., military combat units with a commander and an executive officer).
