Their best purpose I believe, is not to help you launch a successful new business. The best use is to help you “Not” launch an unsuccessful business. The process itself, in many cases, makes you realize that the project was a very bad idea.
Business Plans are still table stakes to play. It does show you at least spent the time to sit down and ask yourself the hard questions.
As I go forward with mine, I will let you know what comes up.
Until we chat again,
