2 The emergence of project management frameworks We can trace the explosion of managerial innovations to co-ordinate and control computing projects to the identification of "the software crisis" at the NATO/Garmisch conference of 1968 [Naur and Rande1l69, Pelaez881. This crisis referred to the way in which software had become the dominant constraint on the take-up of computer-based systems despite rapidlyexpanding markets [Friedman891; software production lacked an intellectual and organisational framework within which detailed prescriptive technical design practices could be deployed, and out of which commercially-viable products could emerge.

92l. Or again, a very detailed and hierarchical division of software labour may provide for a more predictable and controllable labour process. However, it may also place severe strains on the manager's ability to retain or regroup software staff so as to generate new, and more pertinent, kinds of technical expertise to answer constantly changing requirements [Fleck and Tierney91, Friedman89, Tierney91l. Thus, in the forms of "industrial" software engineering which have come into common use in commercial computing practice, the focus is less on software production as a tightly-bounded and rigorously-delineated process, than on the dynamic and open-ended relationship between software and the environment which surrounds it.

For example, functional decomposition quickly became popular in the 1970s, because the procedure allows for many ways of spliting a particular process into functions [Bergland81] whereas structured analysis techniques are more talked about than practised [Friedman89]; modular programming was quickly adopted because it reduced the amount of change during maintenance [Friedman89] whereas Dijkstra's GOTO letter provoked more controversy amongst software scientists than practitioners [Pelaez88]. The "scientific" reform of programming practice has undoubtedly radically altered the management of software production.
