Mission-critical tools

The conclusion I draw from this and my own experience having migrating my fair share of source trees is that the version control system is a first order effect on software, along with two others — the build system and the bugtracker. Those choices impact absolutely everything else. Things like IDEs, by comparison, don’t matter at all. Even choice of methodology might matter less. Although I’m betting there are plenty of software and management teams out there that see version control, build systems and bugtrackers as being incidental to the work, not mission critical tools.
