  Yammer (A)

  Mikolaj J. Piskorski, Kerry Herman and Aaron Smith

  In spring 2012, Yammer was on track to become a highly successful standalone company. Yammer was a leading Enterprise Social Network (ESN), providing companies a private social network in which employees could collaborate securely and efficiently. However, later that year, Microsoft executives unexpectedly reached out with an offer to acquire Yammer for $1.2 billion and integrate Yammer into the Microsoft Office division. An integration with Microsoft would have a profound effect on Yammer's scalability, software development, and organizational culture. David Sacks, CEO of Yammer, debated the challenges and opportunities related to competition, product, and culture as he thought about the offer on the table.

  Domaines Barons de Rothschild (Lafite): Plus ça change…

  Ray A. Goldberg, Arthur I. Segel, Elie Ofek and Carin-Isabel Knoop

  For centuries Lafite has been the most admired wine Estate in the world. How does Baron Eric de Rothschild protect this crown jewel in a conservative manner while DBR develops other Chateaux blending wine programs, reaches out to new areas such as China and begins to take a more active interest in the world's number one market—the United States.
