How can you evaluate the benefits and risks of becoming a franchisor?

"4. You and a partner co-own Swim-Clean, a successful pool supply and cleaning service. Because sales have tapered off, you want to expand your operations to another town 10 miles away. Given the high costs of expanding, you decide to sell Swim-Clean franchises. The idea takes off, and soon you have 25 units throughout the region. Your success results in an invitation to speak at a local Rotary Club luncheon. Prepare a brief presentation describing how you evaluated the benefits and risks of becoming a franchisor, the problems you encountered, and how you established good working relationships with your franchisees.
