Clearly define your type of business. Just think about what football would be without end zones or what the Indianapolis would be without a finish line. Show how you will solve that problem. Use measurable milestones, accountable responsibilities and trackable performance expectations, for starters.
Goals can increase your effectiveness; objectives back your goals and make you more efficient. These resources may already be available within the business or may be generated by future activity. Will you be able to devote yourself full time to the business, financially?
As part of that, you'll assess the business you've chosen to start, or are already running, to see what the chances are that it will actually achieve those ends.
There are a number of pieces that all have to come together to make your business profitable. You also need to make it clear what timeframe the business plan covers - this will typically be for the next 12 to 24 months.
This review process should follow an assessment of your progress to date and an analysis of the most promising ways to develop your business.
