A business plan is not a document you create once and store in your bottom drawer. It is a living guide that you should develop as your business grows and changes. Successful businesses review and update their business plan when circumstances change.
While every business owner should have an ongoing planning process to help them run their business, not every business owner needs a complete, formal business plan suitable for submitting to a potential investor, or bank, or venture capital contest. So don’t include outline points just because they are on a big list somewhere, or on this list, unless you’re developing a standard business plan that you’ll be showing to someone who expects to see a standard business plan.
Make it clear and concise; include only the most important elements, keeping it at a maximum of half a page. To create the summary go back over your plan, pick three or four key messages and write a brief overview, then conclude with details of the action you want the reader to take.
Even though the summary will be read first, it is easiest to write it last – providing an overview of the complete business plan. The aim is to draw the reader in, so what you include will depend on your audience. If you are seeking funding you need to really sell your business idea in the summary.
