Our first instinct, in most change situations, is to offer up data to people’s Riders: Here’s why we need to change. Here are the tables and graphs and charts that prove it. The Rider loves this. He’ll start poring over the data, analyzing it and poking holes in it, and he’ll be inclined to debate with you about the conclusions you’ve drawn. To the Rider, the “analyzing” phase is often more satisfying than the “doing” phase, and that’s dangerous for your switch.
