A business plan is nothing but a written outline of where you currently are and how your business will develop. This plan revolves around the framework of your organisation along with the history and goals of your business. A complete business plan should act as a guide to how you operate the business and as a proposal to potential investors. A full-fledged business plan starts with the Title Page and ends with the Financial Picture (business funding). In between, you mention Mission Statement, Executive Summary, Market Strategy, Competitive Analysis (SWOT), Design & Development, and Disaster Management. These are some other vital components of the blueprint of your business plan.
While your business plan is a reflection of your business, you must ensure you sum it up in a way that does not look too bulky or equivocal. You'll also have to modify the plan as your business evolves since the business plan is a living strategic document for your organisation.
