Attention to detail. A plan that is concise and clear reads professionally so don't make yours too wordy. The reader needs enough detail and information to be able to make an informed decision. As with all professional documents, care must be taken to avoid spelling mistakes and use correct grammar and punctuation. A plan that makes absurd or unrealistic assumptions is of no use so stick to the facts and make sure you are making credible projections and accurate content at all times.
Plan of Operations : Think of this as how you are going to spend a day at your business. How will work get done, from taking orders through to delivery? This can really help you to understand how your business will work and any potential problems or room for improvements.
Traditionally business plans have been highly confidential and quite limited in audience. The business plan itself is generally regarded as secret. An open business plan is a business plan with unlimited audience. The business plan is typically web published and made available to all. In the free software and open source business model, trade secrets, copyright and patents can no longer be used as effective locking mechanisms to provide sustainable advantages to a particular business and therefore a secret business plan is less relevant in those models.
Do your research. In order to be able to write a strong, comprehensive business plan you need to possess a sound knowledge of the market you are involved in. You need to actively conduct market research and ensure that your plan makes reference to your findings. It should include factors such as market size, the predicted growth path of said market and how you propose to gain access to it. For example, if you are planning on opening a bar then your business plan should include figures based on the local population, cost of suppliers, predictions about whether the bar industry is likely to grow or decline in the area and a review of the competitive environment.
