This article presents a problem-solving model to examine the often problematic relationship between expertise and creativity. The model has two premises, each the opposite of a common cliché. The first cliché asserts that creativity requires thinking outside-the-box. The first premise argues that experts can only think and problem solve inside the tool boxes of their expertise. The second cliché, that creativity requires freedom from constraints, points to the problem with expertise. Free to do anything, experts repeat what has worked best in the past. A solution is suggested by the second premise: to circumvent the liabilities of expertise, creativity requires constraints of a particular paired kind. The model is introduced as an expansion of prior process models focused on problem identification and construction. Problem-finding is reanalyzed as constraint-finding. A case study shows how one recognized creator, painter Chuck Close, uses constraints as a tool to solve the expertise-creativity problem.
