Introduction of
Analysis of the potential integration of novel proven practice methods with current
practices of requirements management within TOGAF
The
requirement management is a process which is tracing, analyzing, documenting as
well as prioritizing the requirements as well as controls the change of communication
which is related to the stakeholder. Requirement management is the continuous
process in the whole projects whereas the requirement is the capability where
the outcome of the project should also conform. TOGAF is the “the open Group Architecture framework”
for the architecture of enterprises which also provides the methods of implementing,
planning as well as designing the enterprise's information technology
architecture. Therefore the TOGAF is a high-level method for design which is
modeled at a four-level.
The
requirement management is a significant activity in managing as well as designing
the enterprise architecture (EA). Therefore the goal of the diffident
stakeholder from a base is changed for any organization. And it is also
translated for the organization requirements architecture that also reflects the
requirements and it is realized through the services of software, and the day
to day operations. ADM (architecture development method) in TOGAF’s is the requirements
management which is the central process and it applies for the different stages
of the ADM cycles. However, the TOGAF has
shown the requirement for requirement management as well as refrains for the
recommending and the mandating of exiting methods with these tools of
requirement engineering (Engelsman et al, 2010).
The
requirement management in the TOGAF is also shown the different structures
which facilitate various applications in an ADM, and thus this white paper
presented the method of the potential integration for the novel has proven practice
and it is also based on the requirements engineering cycle. Enterprises
architecture is the design of the management function for an enterprise which
is not an easy task. There are different frameworks along with the enterprise management
tools that also promise to deliver the various guidance of the enterprise's
management. In this research paper the architecture framework for the TOGAF
along with the promising detail which is a highly generic development
architecture method. Then this type of paper also presented the generic
development which steps could also complement through the pattern that is based
on the Enterprises architecture management. The requirements management is the
ongoing process that is playing a significant role in the TOGAF or ADM and the
process of requirement management is also related to the ADM phases. The guidance of the TOGAF which offers the
actual requirement management and it is limited than the methodology along with
the modeling of requirement management is the well-aligned by both TOGAF along
with the ArchiMate enterprises modeling architecture.
For
the potential integration of novel proven practice methods with current
practices of requirements management within TOGAF in this paper then explained;
·
Way of thinking that is also explained the
principles, philosophy as well as assumptions that are underlying the method of
requirement and that management which is approached.
·
The way of working that is also explained
the reference method which identifies the structure of requirement management
activities by the TOGAF ADM phase.
·
Way of modeling that describes the concept
of goals, principles, architecture, requirements, and stakeholders.
·
Way of supporting that describes the
method of analyzing as well as viewing of requirements model along with support
tools (Quartel et al, 2010).

The
requirement engineering which is concerned by the process of determining a solution
for several problems. Thus this type of concern could also approach the problem-oriented
view that is also focused on the various understanding of problems along with
the oriented view that focused on the selections along with the design of
solution alternatives.
By
applying the different views which are alternatively and could also identify
the problem chain, and every chain links also connected by the problem solution
like the solution supposed against problem through the next chain. The business
analyst might be investigated the business problem along with the specified
business solution for the problem, and the new solution which is most likely
required IT supports as shown in the below figure;
In
TOGAF the principle architecture governs the process of architect for the
implantation when the guide along with the constraints of the design
implementation of the decision taken in the development process. While TOGAF
provided a cyclic process model, which has all the ingredients like the
description of objectives, overview of the approach, the inputs which are
required, which steps are to be executed, the output which will be the result
of all the above step and this output might be the input of next ADM cycle. The
way of thinking which enables the traceability by enterprise architecture and
the element could also be traced back to the principle, a motivated goal.

As
explained above in the way of thinking this idea also advocate the way of
working in the enterprise architecture where every chain translates the current
architecture of model into the detailed and solves the various problems. The principles
into the management requirements which is existing by the new elements of the enterprise's
architectures like the product or services along with the organization applications.
In the below figure which is also shown the relationship among the motivation
models along with the architectures of the model as well as indirectly of the relationship
among requirement management and the architecture process. The requirements management
which is encompassed by the requirement engineering that’s also refining, analyzing,
modeling and principle requirements (Foorthuis et al , 2008) ;

There
is the core concept of ArchiMate which is focused on the extensional enterprise
aspects and the appearance of the operational entity is included in the
intentional aspects where the business goals, principle, requirements which motivate
the enterprise designs and not covered through the core concepts (Quartel et
al, 2010)

A
requirements model may grow quickly in subsequent RE cycles. Furthermore, the
relationships involving some goal, principle or requirement may be distributed
over different views of the model. Therefore, tool support to create,
manipulate and analyze requirements models is indispensible. Model creation and
manipulation requires an editing tool that supports both the ArchiMate core
concepts and the motivation extension (Chen, 2008).
Research
methodology of Analysis of the
potential integration of novel proven practice methods with current practices
of requirements management within TOGAF
In
February 2009, version 9 of “The Open Group Architecture Framework”
(TOFAG) framework was presented which superseded the TOGAF version 8.8.1. This
version of TOGAF introduced some additional keeping in mind the support of the EA
management approach. Below are the main features which were introduced in
version 9 of TOGAF.
Content
Framework: To improve the
consistency in all of the created deliverables, TOFAG 9 introduced a content
framework with a model of architectural work.
Modular
structure: The resource base of TOGAF version 8.1.1 was
modularized in TOGAF version 9 to improve its usability and incremental
adoption.
Extended
Guidance: The TOGAF version has been extended with a logical
information model and it also contains a capability framework that included the
very important definition of skills, responsibilities, organizations, and
roles.
Architectural
style: This feature is very important in TOGAF version 9
which provided additional guidelines to adapt the process of TOGAF in specific
situations like security architecture or service-oriented architecture (SOA).
Figure:
Architecture development method cycle
TOGAF version 9 mainly
consists of 6 parts. The above diagram represents the ten different phases in
an EA development considered as a generic method. TOGAF version 9 presents’
different ways using which people can adapt the method to the different process
styles of their needs are it also caters to different enterprise levels. The
content model in version 9 TOGAF is one of its novelties. It gives a metamodel
for describing different architectural artifacts. But TOGAF does not impose its
use and other conceptual metamodels like the ArchiMate model can also be used.
Complementing TOGAF using
the Enterprise Architecture Management Pattern Catalog
The
EA catalog provides the best practices which can be used the address the
typical EA management concerns. The best practices employ their process
descriptions. Due to this limitation, the catalog does not provide all overall
process descriptions. While TOGAF provided a cyclic process model, which has
all the ingredients like the description of objectives, overview of the
approach, the inputs which are required, which steps are to be executed, the
output which will be the result of all the above step and this output might be
the input of next ADM cycle. So, the generic methodology of TOFAG can
complement the EA management catalog best practices. The TOFAG starts with a
preliminary phase and it initializes the EA management approach. The tasks
which are usually performed during this phase are the definition and
establishment of the EA team, the implementation of the supporting tools.
Usually, architecture guidelines are principles that are also defined during
this phase. After the completion of the preliminary phase, the Architecture
vision phase (A) is initiated.
The
main purpose of this phase is to identify the relevant stakeholders also
identify what their concerns might be. In TOFAG, no procedure is defined to
gather the relevant concern of the stakeholders is identified. Here the EA
management pattern catalog can complement TOFAG as it lists the typical
concerns in the context of ES management. These concerns can be used as input
to the stakeholder which is identified using TOGAF. After the completion of
phase A, the corresponding business, information system, technology
architecture is developed in Business Architecture (B), Information Systems
Architecture (C) and Technology Architecture (D) phases. These three
architectures are fundamentally very similar to each other. TOGAF uses baseline
architecture and a gap analysis is required to evaluate the difference between
baseline architecture and target architecture that is going to be used. Here
the EA management pattern catalog can also complement TOGAF. As TOFAG describes
a generic model; the EA management pattern catalog can help facilitate the
adaption to the specific needs of an enterprise.
The
first step is to gather only the relevant information that is needed to make
informed decisions to the scope of architecture effort. Here EA management
pattern catalog can be used; it supports the concern-driven approach which can
be used to deduce the relevant information. The next step is to determine the
overall modeling process. To do this EA management pattern catalog can be
consulted for the best practice solutions. The next step in this phase is to
identify the required visualization and here EA management pattern can help
ensure the suitability of the models. The next phase is Opportunities are
Solutions (E) and it concerns the use of intermediate architectures for
transformation from baseline architecture to the target architecture. This
phase includes different kinds of refinements. Here EA management catalog can
help generate possible planned architectures.
The next phase is the Migration Planning phase
(F), which deals with the implementation of some or all the planned
architectures. The main steps of this plan are the business value assignment
and prioritization of the project. Here EA management pattern catalog can help
plan which leads to certain demands regarding the information model and it also
helps with the visualization which is needed in this phase. The next phase in
the process is the Implementation Governance phase (G) where the selected projects
in the previous phase are executed. The main steps in this phase identification
of deployment resources and skills also monitor the execution of the project.
Here EA management pattern catalog helps with the implementation concern
through best practices solutions. The next phase Change Management phase (H)
which also concludes an ADM cycle concerns the changes are required in the
architecture. The key tasks here are to monitor the deployment techniques and
develop change requirements (Buckl et al, 2009).
Conclusion of Analysis of the potential integration of novel proven
practice methods with current practices of requirements management within TOGAF
Summing
up all the discussion the research paper is about the requirement management in
the TOGAF for the analysis of the integration of novel based proven methods
using current practice. In this white paper, the discussion is also about the
ADM of TOGAF that provides the guideline for executing as well as establishing
the enterprise architecture process of management. The pattern is based on enterprise
architecture management and it is also presented by the enterprise management catalog
which is discussed and provides guidance for addressing the specific concerns. As
TOFAG describes a generic model, the EA management pattern catalog can help
facilitate the adaption to the specific needs of an enterprise. TOGAF uses
baseline architecture and a gap analysis is required to evaluate the difference
between baseline architecture and target architecture that is going to be used.
