How to write a great business plan

I read an old article by William Sahlman "How to write a Great business plan". It was published on July 1997 Harvard business review, almost 10 years ago. However, the essential part of a business plan has never been changed.
Here are some thoughts I learned from that article:

• Don't spend too much time to image the numbers, and ignore the information that really matters.
• Put break-even projections and positive figures into the back of plan.
• Great business plan contains four parts: the people who start and run the venture; the opportunity whether the business can grow and how fast it could be; the context of big picture; and the risk and reward assessment.
• The people is important since ideas are a dime a dozen; only execution skills count. The questions like who are they, what's their experience in industry, what's their relationship and reputation in industry, etc matters a lot.
• Investors prefer large and rapidly growing markets with a significatnt scale(that could be $50 million in annual revenues) within five years or as soon as possible.

There are a lot of shining points in this old-but-still-valuable articles. I would suggest whoever has a small business dream should read it. It will help you to understand what VCs are looking for although I haven't apply it and verify it in my real life.
