But your idea may be so new that you may also need to talk to potential customers, host some focus groups, talk to an ad agency, or maybe even make a prototype and float it past some people. Be prepared to spend the time. Remember, it's not about the Plan but the Planning.
Service Operation - If a service is offered, describe it. Will the work be done by company personnel or subcontracted? Who are the subcontractor(s)? If on-site or in cyberspace, what employee qualifications, equipment, and technologies are needed? How will quality be assured? What performance levels are anticipated per employee? Possible Data Sources: local Chamber of Commerce; yellow pages; trade associations.
One key component critical to your success is scoping the competition. A business plan consultant studies the area where you will be located quite thoroughly. For example, if you plan on setting up a coffee shop on Main Street, or within the vicinity, the small business consultants you consult with will inquire about the number of existing coffee shops and the services they provide.
While these are easily available online, some of them are way better than the others. A lot depends on the approach that goes into writing the business plan.
