A business plan is a written document that describes in detail how a new or existing business will achieve its goals, define its strategy and outline its financial projections. It typically includes sections on market analysis, management and organization, products and services, marketing and sales, operations, and financial projections. The purpose of the business plan is to serve as a roadmap for the business, outlining specific strategies and tactics that will help it succeed in its chosen market. A well-written business plan can also be used to attract investors or secure loans, as it demonstrates the feasibility and potential success of the venture.
