Problem
This question is considering these two HBS cases:
• Cola Wars Continue: Coke and Pepsi in 2010 (Authors: David Yoffie): 9-711-462
• Domino's Pizza case (Authors: David Bell, Phillip Andrews, Mary Shelman): 9-512-004
Consider the Dominos and Cola cases and explain, conceptually, when should a company consider an exclusivity relationship with a supplier and/or buyer?
