Let me be clear, I am not suggesting all work should be preplanned. It is irrespon-sible (maybe even delusional), to believe that it’s possible to know everything up front while planning a complex project. Quite the contrary—we don’t know much about what we don’t yet know. Sometimes changes in direction are necessary, because new information emerges as we work to solve problems. A major value of the Agile movement is to encourage responding to change over following a plan.
