[Video Link] Here's an excerpt from the new book, Running Lean: Iterate from Plan A to a Plan That Works, by Ash Maurya. It's published by O'Reilly (which also publishes MAKE, the magazine I edit).
Running Lean is an ideal tool for business managers, CEOs, small business owners, developers and programmers, and anyone who's interested in starting a business project.
Find a problem worth solving, then define a solution
Engage your customers throughout the development cycle
Continually test your product with smaller, faster iterations
Build a feature, measure customer response, and verify/refute the idea
Know when to "pivot" by changing your plan's course
Maximize your efforts for speed, learning, and focus
Learn the ideal time to raise your "big round" of funding
