Developing and Selecting Solutions Graham Parker’s Structured Problem Solving Guide describes the problem solving process in four phases, one of which is Developing and Selecting Solutions (Phase 4). The other phases are not summarized here, however, it is noteworthy to mention that Phase 4 is the entering into solution development, whereas during the first three Phases of the process, specific problems of study have already been defined, a selection process is undertaken to decide which problems to address, and finally the problem to be studied is characterized by the collection and analysis of the data to be studied.
