In a nice comment on some of the core ideas in Discovery Driven Growth, a blogger from the Hindu Business Line describes a point we make in the book as useful. That is that you are better driving your projects from key decisions points rather than date milestones. The reason it matters so much, we have argued, is that when something is very uncertain, predicting dates can be nearly impossible, You usually can, however, anticipate the next major checkpoint and plan towards that. If people are given permission to replan at such key points, we suggest, there will be less escalation of commitment to failing courses of action and faster progress.
