For software projects, chance and history so clearly play a role that you won't get embroiled in the equivalent of the science wars for saying "the feature set of Microsoft Word was not inevitable". I even hope that, in my paper, I'll be able to say that the composition of Extreme Programming isn't inevitable - that its state today depends on chance happenings at Xerox PARC, Tektronix, University of Oregon, Chrysler, and Ward Cunningham's office (where one day he decided to make a wiki).
One of the links in the post has this gem "the simultaneous reconstruction of social contexts of which they form a part - labs simultaneously rebuild and link the social and natural contexts upon which they act." Whao, nelly! I ain't seen the like since my days in Waggener Hall.
