I've just finished reading this short book. It explains Kotter's Eight Step Process for Change that he first described in more conventional form in Leading Change and then Heart of Change. It tells the story of a colony of penguins who eventually commit to abandoning the iceberg they have inhabited for generations.
Whilst it won;t make the Man Booker shortlist next year, I found the fable subtle, realistic and rich enough to keep me reading, and it didn't take long to read the 147 pages of large type, several of which were devoted to some very attractive colour illustrations of points in the story. The story illustrations of Kotter's model were good, and the penguin characters had some familiarity, particularly NoNo the influential saboteur, who did all he could to oppose the change.
This is designed as a more accessible format for the type of manager who would rather freeze on an ice floe than read a research-based management book such as Kotter's original Leading Change. The authors researched how some of the key messages of Kotter's work could be better communicated through story-telling and enhanced by good pictures.
And I think the authors have pulled it off. I can see this book going down well in certain team contexts or change management training courses. Well worth checking out, and it won't take much time to read.
