Business plans may be internally or externally focused. Externally focused plans target goals that are important to external stakeholders, particularly financial stakeholders. They typically have detailed information about the organization or team attempting to reach the goals. With for-profit entities, external stakeholders include investors and customers.
Non disclosure agreements (NDAs) with third parties, non-compete agreements, conflicts of interest, privacy concerns, and the protection of one's trade secrets may severely limit the audience to which one might show the business plan. Alternatively, they may require each party receiving the business plan to sign a contract accepting special clauses and conditions.
Finally, a business plan should be error - free. This is important because your business plan defines who you are as a business person. If it turned out sloppy, then that does not speak too highly of you.
It should include a market research that identifies your competitors, their share of the market and the range of the products they produce. By learning how they conduct their operations, you may learn tricks of the trade in the business you want to enter and you also get to have a basis on what you can do to excel.
