So if you can put this all together, you can have a complete business operating plan that would show you exactly what your business would need to do to give you the income and profit you would like to have and a rough idea whether your market would support it or not. All you would have left to do would be to figure out how to make it all happen.
Then there are the moments when something seems to be going wrong, when one or more areas of the business just don't seem to be working. Cash flow is anemic or the marketing message is flat. Perhaps customers have shown a marked interest in only one particular product or service, ignoring all your other offerings. This means it's time to revisit your business plan, more precisely it's time to revisit the questioning process that helped you craft your plan.
