Foreword: Why Scrum Works

Foreword: Why Scrum Works

Suppose I’m traveling from Chicago to Boston by airplane. Before and during the flight, the pilot gets instructions from air traffic control. We take off on command and follow the prescribed route. Once we are in the air, computers predict almost to the minute when we will land in Boston. If things change—say the air is bumpy—the pilot must get permission to move to a different altitude. As we approach the airport, the pilot is told what runway to land on and what gate to go to.

If, however, I set out for Boston in a car, I can take whatever route I want, whenever I want. I don’t know exactly when I’ll get there, and I probably haven’t planned what route I’ll take or where I’ll stop for the night. En route, I follow traffic laws and conventions: I stop at red lights, merge into traffic according to the prevailing customs, and keep my speed consistent with the flow. In an automobile, I am an independent agent, making decisions in my own best interests framed by the rules of the game of driving.
