The best plans tend to be written by the most experienced teams who have had the benefit of writing plans that were successfully funded over many years. There are several "off the shelf" programs which accelerate the development of a business plan, but the originality and completeness of the document plays a key role in differentiating the company's proposal on the investor's desk.
Business Planning tools are designed to help the company develop it's Business Plan faster and more in touch with investor's needs. Well developed Business Plans may be expanded into Operating Plans for tactical execution by department managers.
