Project definition continues to be very problematic in Information Systems. Attempts to ‘nail down’ the definition of projects reflect what Mitroff and Linstone[1993] call an overly ‘technical’ or objective perspective. Rather a more social constructionist method is required. The authors arranged a small ‘town and gown’ colloquium to explore the problems and possible solutions to project definition. Drawing on this, and many years of their own project definition experience, the paper argues that project definition has to be explicitly treated as something that will constantly grow with client and designer interaction. Some pragmatic methods that align with this view are suggested.
