Test Run Your business idea may look good on paper, but how will it fare in the real world? Run a feasibility test and find out.

In 2002, when Farshad Tafazzoli started Delray Beach, Florida-based Zoli Corp., it was made up of little more than a series of hip-shooting analyses and his willingness to take a chance. "I looked at everything with an open mind and made a gut decision," says Tafazzoli, 35, who projects 2007 revenue of $3.1 million for his high-end plumbing products company.

Entrepreneurs typically take a similar approach to evaluating the feasibility of ideas for new businesses, focusing on developing their product or service instead of assessing the business's feasibility.
