Mcdonald's core competencies

Please answer the following discussion questions:

Question 1 – McDonald’s

Conduct a value chain analysis for McDonald's. What are its primary activities? What are its support activities? Identify the activities that add the most value for the customer. Why? Which activities help McDonald's to contain cost? Why?
In the last few years, McDonald's has made a lot of changes to its menu, adding more healthy choices and more higher-priced items, such as those offered in McCafé (e.g., premium roast coffee, frappé, and fruit smoothies), and has also enhanced its in-restaurant services (e.g., free, unlimited Wi-Fi, newer interiors). Did McDonald's new priorities—in terms of a broader, healthier menu and an improved in-restaurant experience—require changes to its traditional value chain activities? If so, how? Try to be as specific as possible in comparing the McDonald's from the recent past (focusing on low-cost burgers) to the McDonald's today.
Question 2 – The Resource-based view

The resource-based view of the firm identifies four criteria that managers can use to evaluate whether particular resources and capabilities are core competencies and can, therefore, provide a basis for sustainable competitive advantage. Are these measures independent or interdependent? Explain. If (some of) the measures are interdependent, what implications does that fact have for managers wanting to create and sustain a competitive advantage?

Please answer the following ethical/social issues question:

Question 3 – Loss of key personnel

The chapter mentions that one type of resource flow is the loss of key personnel who move to another firm. Assume that the human resources department of your firm has started running ads and billboards for open positions near the office of your top competitor. Your firm is also running Google ads on a keyword search for this same competitor. Is there anything unethical about this activity? Would your view change if this key competitor had just announced a major layoff?
