How should prospective franchisees evaluate a franchise opportunity?

"Offering Circular (UFOC) for that franchisor, and read it thoroughly. The Federal Trade Commission (FTC) requires franchisors to prepare this document, which provides a wealth of information about the franchisor, including its history, operating style, management, past or pending litigation, the franchisee’s financial obligations, and any restrictions on the sale of units. Interviewing current and past franchisees is another essential step. And most franchise systems use computers, so if you are not computer literate, take a class in the basics. Would-be franchisees should also check recent issues of small-business magazines such as Entrepreneur, Inc., Startups, and Success for industry trends, ideas on promising franchise opportunities, and advice on how to choose and run a franchise. The International Franchise Association website at http://www.franchise.org has links to Franchising World and other useful sites. (For other franchise-related sites, see the “Working the Net” questions.)"
