Ballard IGLC-8 5<strong>design</strong> tasks. It is one of several modules <strong>in</strong> the ADePT software developed atLoughborough University (Simon et al. (1999). DSM is appropriate when a specific<strong>design</strong> direction has been established or for the exploration of alternative <strong>design</strong>sequences. Once iterative loops have been m<strong>in</strong>imized, this author proposes that selectionbe made from among the strategies presented below <strong>in</strong> order to manage each of thoseloops.A major contributor is sequential process<strong>in</strong>g, which adds to the time expended on theproblem, but also actively h<strong>in</strong>ders resolution. The architect (or anyone else) could havecalled a meet<strong>in</strong>g to decide as a group on the values for the relevant dimensions. If thevarious contributors to the decision had been together <strong>in</strong> one place, at m<strong>in</strong>imum therecould have been an acceleration of the iterative loop<strong>in</strong>g. At best, there could have beengenu<strong>in</strong>e team problem solv<strong>in</strong>g.
