High-Tech Ventures by Gordon Bell

After 11 years this book remains a great resource for everyone who evaluates a starup's health or is thinking about starting a business. The book contains a very comprehensive set of really good questions that evaluate the business in every dimention critical to its success. The success is assured if you have the right answers to all of the test questions presented in the book. Great resource for high-tech enterpreneurs, VCs, hires.

Word of caution though. This book isn't really about how to build a successfull business. It's more about how to tell if a given business (or a business decision) is to be successful. Most of the case studies in the book are really annotated examples of falures, as oppose to examples to follow

Highly recommended.
