A Penguin’s Progress

by David Meyer

Best-selling author John Kotter teams with Holger Rathgeber to present an accessible fable about change initiatives. For many years now, their lovable penguins have been the best change-management teachers around. 

In this bestseller, now in its 10th anniversary edition, John Kotter and Holger Rathgeber, both organizational performance and change experts, use the model of a fable to teach readers how to institute successful change in today’s tumultuous world.

Kotter is an award-winning author and a professor emeritus of leadership at the Harvard Business School. He co-founded the consulting firm, Kotter International, where former Fortune 500 executive Holger Rathgeber – also Kotter’s co-author for That’s Not How We Do It Here! – is a principal.
