If there is one thing that is certain, doing more with less mentality has killed software development. Having a developer / programmer / analyst / tester / technical writer /etc., instead of multiple people to fill each each role, diminishes the overall role the SDLC (software development life cycle) plays in software development and maintenance. It does not mater what approach or methodology you use in getting software modified, there are defined stages in how software gets changed. I must stress software modifications, because new development in most companies is dead. Once the software is developed, it is maintained. Maybe it’s me, but most of what I read today about the various development methodologies focus on new development. Maybe maintenance is implied, but I think that most company leaders see the approaches as related to new development. This is simply not the case. The SDLC applies to change within the software and its related systems, not just new development.
