That about sums it up. I've used Project some, and have looked at several other books before this one. This book provides the detail and clarity to get the ideas across. One particular example ... effort driven scheduling and fixed units versus fixed duration, etc ... a tricky topic, and this book does it better than any other. Best book I've seen on the subject!
