I read this when it originally came out in the early 2000's. I just finished re-reading it again (I wonder who snagged my copy from 2001???) I was amazed at:
1) how much of it I remembered;
2) how timely the concepts still are 20 years later;
3) how so many of the ideas he put forward in this book have since become 'main stream'.
A business classic that probably should be read every couple of years. It's actually a pretty quick read for a business book. The ideas are very accessible.
