Hands on. That's what he practised and preached. 50 years of management experience is great to call upon, but I do suspect some more academic theory would have allowed him to scale up to the Apollo and ISS era in NASA slightly better. What clearly was visible was when the vision as clear, execution is paramount, and total commitment yields results. Lots of good practical lessons for managers today however. Being tough and competent is not optional if you want that high performance team
3 stars as the book does lull in parts, but it does have a strong finish
