Thanks, Alistair --abstract follows-- It is difficult to identify and locate the pattern that you need. This paper presents a locating scheme based on sensations and symptoms that cause you to look for a pattern. It is tried with project management patterns because they carry symptoms and sensations suited to the medical metaphor. The reader is invited to consider whether this locating scheme works for other patterns. Even just with the Design Patterns book, people comment they dont know how to find the pattern they should be reading. With the increasing number of patterns available, that task is getting harder. At an informal gathering, Martin Fowler described the medical system of the British National Health Service, and it seemed remarkable how similar the medical problem is to the patterns problem. A doctor needs to diagnose a situation, run a procedure to check the diagnosis, and then make a recommendation. The problem facing doctors, as pattern readers, is the large number of possible diagnoses, and the need to find the right one. The decision of what to use depends on sensations and symptoms (a sensation is what the patient is feeling, a symptom is what the doctor detects). A catalog of project management risk-reduction patterns is a good place to apply the medical metaphor, since the situation implies there is already a sense of discomfort. The catalog would be several hundred pages long. How would a person find the right pattern to apply? I propose: by issue, by sensation and by symptoms. The catalog contents are first divided into chapters by primary issue: productivity, communication, distractions, efficiency, quality, etc. A diagnosis table of sensations and symptoms helps the reader find proximate and crossover patterns. This paper shows the diagnosis table and five representative patterns. More patterns are listed in the table than there is space for in the paper. --end of abstract--
