Dirk Van de Put

Mondelez International's orderly succession planning is sweet inspiration for a situation that could soon turn salty. The $66 billion snack purveyor named Chief Executive Irene Rosenfeld's replacement, reaching outside its ranks for frozen-food executive Dirk Van de Put. Others would do well to emulate the process, but the new boss may still walk into a merger fight.

The Oreo maker isn't immediately showing Rosenfeld, 64, the door. She plans to step down as chief executive in November but will stay as chairman before Van de Put assumes that title, too, after the first quarter next year. Rosenfeld will help with the transition, guiding Van de Put through the various lines of its global business spanning products from Cadbury chocolates to Ritz crackers to Trident gum.
