The document outlines 15 reasons why entrepreneurs should prepare a formal business plan, including to clearly explain the business opportunity and provide a roadmap for stakeholders, hold founders accountable, identify resource needs, minimize risks, provide financial controls, and demonstrate that the executive team can articulate a comprehensive plan that details economic viability. Preparing a plan can also help educate and recruit employees, minimize litigation, determine feasibility, and show how the product or service solves problems for customers. The document was written by Hal Spice of Sente Capital Management to advocate for the importance of business plans, especially in difficult economic environments.
