Our exploration will come in three stages. First, we’ll grapple with the three forces that push us downstream, impeding our ability to prevent problems. Then, in the heart of the book, we’ll study the seven fundamental questions that upstream leaders must answer. We’ll study both successful and unsuccessful prevention efforts, uncovering strategies that succeeded and obstacles to beware. Finally, we will consider “far upstream” thinking: What do you do when you’re facing a problem that has never happened before (and may never happen at all)?
