the activities that add the most value for

the customer. Why? Which activities help McDonald’s to contain cost? Why?

b. In the past 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., pre- mium roast coffee, frappé, and fruit smooth- ies), and has also enhanced its in-restaurant services (e.g., free, unlimited Wi-Fi; upgraded 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 of today.

What other industries can you think of that can be disrupted by this new business model? Where do you see “excess” space or other assets that could perhaps be utilized more efficiently?
