Agile in the early 1990s? The first XP project wasn't until 1999 at Chrysler if I'm not mistaken. Of course, one man's agile is another man's DSDM (which isn't really that agile), and some people would argue that development methods were originally agile, and then got bastardised over time. At least that's what Craig Larman said about it, I think.

Uh, no. IBM Jazz has no relationship to ALF whatsoever (although both are related to Eclipse)
