The Creative Problem Solving (CPS) method provides a framework for problem solving of very general applicability. It should be used whenever an unfamiliar problem is to be addressed; when the accepted solutions to a familiar problem do not appear to be satisfactory; or when the penalties for a less than optimal solution are severe, e.g. when contemplating major investment or major organisational or process change.
The problem solving process is divided into three stages. Each stage is made up of a divergent phase, where large numbers of issues, ideas or solutions are generated, and a convergent phase, where these ideas are grouped, classified and selected.
