The franchised system
The principal benefit which franchisors offer for prospective franchisees is the opportunity to run a business which has already proven its capacity to deliver products or services profitably to an identified market.
You cannot sell an idea as a franchise. You must have proven in practice that the idea works and that you can successfully transfer the "know how" to another person operating at "arms length" from you.
You will need to draw up and prove a comprehensive operations manual that details what a franchisee does, how they are to do it, and to what performance and quality standards. The manual(s) will need to cover the setting up phase as well as continuing operation.
You will also need to develop and prove an initial and continuing training programme that ensures that the "know how" contained in the operations manual(s) can be transferred successfully to a third party within the time available.
The work involved in proving and documenting your operating and training systems is extensive and ordinarily calls for highly skilled and experienced advice.
