Very worth reading. I think the exercise of creating a detailed enough business model is a must for any entrepreneur because during this process all possible “what if” scenarios should be considered. This is like an entrepreneur’ soul search activity. The more “what if” answers to any model idea the better.

With that said, I think Janet’s most important point is “from there, try to ascertain how flexible & creative, in terms of tweaking the b-model, the entrepreneur might be if the market changes, war starts, economy falters.”

Creating a business model layout is like planning the route to take for a very long trip with the family. Seldom do you get to stay within budget, convince everyone to move according to your schedule (those damp bathroom stops), and guarantee the weather or car troubles do not mess up any of your plans. Oh, and sometimes, you do get lost.
