Designing a methodology is not at all like designing software, hardware, bridges, or factories. Four things, in particular, get in the way:
* Variations in people. People are not the reliable components that designers count on when designing the other systems.
* Variations across projects. The appropriate methodology varies by project, nationality, and local culture.
* Long debug cycles. The test and debug cycle for a methodology is on the order of months and years.
* Changing technologies. By the time the methodology designer debugs one methodology design, the technologies, techniques, and cultures have changed and the design needs updating.
No wonder it is so hard to get this stuff right. It keeps things interesting though.
