A business plan can be used as a vehicle for accurate communication among principals, managers, staff, and outside sources of capital. It will also help to identify, isolate, and solve problems in your structure, operations, and/or finances. Along with these advantages, a business plan captures a view of the big picture, which makes a company better prepared to take advantage of opportunities for improvement and/or handle crises.
For long term maintenance of competitive advantage, a firm must ensure that its methods cannot be duplicated or imitated. This requires constant analysis and regular reinvention of competitive strategies.
Marketing Analysis/Strategy: The next thing to write (after the general description) should be your marketing strategy. For new or existing businesses, market analysis is an important basis for the marketing plan and will help justify the sales forecast. Existing businesses will rely heavily on past performance as an indicator of the future. New businesses have a greater challenge - they will rely more on market research using libraries, trade associations, government statistics, surveys, competitor observations, etc. In all cases, make sure your market analysis is relevant to establishing the viability of your new business and the reasonableness of the sales forecast.
