Here is a recap of where we are in this discussion: Business plans formalize an understanding of the task with appropriate analysis leading to a plan_of_action. Not all business plans are for profit motives. Business plans are for an enterprise effort and not focused on disciplines/departments, e.g. Marketing plan, sales plan, HR plan, supply chain plan, etc. Business plans are a great vehicle to build a team effort. Plans can be utilized for formalizing metrics relative to achieving goals and performance measurements. Some complex plans might include a Project Management professional. There are internal and external audiences for business plans. Most external focused plans are for outside funding of projects. Be mindful of the 'tone' the plan projects to the reader. Tone refers to the impression a person gets from reading the plan; a subliminal feeling about the plan.
So why make a business plan? I want to show you a totally different kind of business plan. What if you made a business plan that focused only on what you want for your life? You have dreams about what you would like your lifestyle to be, right? Why not make a business plan that could give you those dreams? What would your business look like if it gave you exactly what you want in life. What kind of salary would your business need to give you? Why not build a business plan around that? Decide how much salary you would need to support your dreams and then build a business plan that would show exactly how your business could give you that. Wouldn't it be better to have your business work for you instead of the other way around?
