Ken Blanchard, author of the book’s Foreword, co-wrote with Spencer Johnson the bestselling business productivity book The One Minute Manager. At his own company, Blanchard handed out early copies of Johnson’s Who Moved My Cheese? during a stressful time and found that his staff loved the book for its ability to help them adapt to, and build on, challenges the company faced.

Sniff is a mouse who lives in a Maze, along with another mouse and two very small humans. As Sniff’s name suggests, this mouse constantly tests the maze for odors that hint at the presence of cheese. If the cheese in one corner of the Maze disappears, Sniff immediately begins searching for more. By contrast with the humans, Sniff and the other mouse, Scurry, “do better when they are faced with change because they keep things simple” (17).
