Mark Levison: "I've started a page on the Scrum Alliance wiki to document Agile/Scrum Failures. The failures are not of the process itself but of the humans associated with the project. "
It's courageous to put up a failures page (or what some companies call a 'blackbook'). But there's a problem with the "humans" part of that quote - processes get a pass when projects fail becuase when the project fails, issues are ascribed to people. Contrariwise, I don't tend to see XP/Scrum/Prince/Waterfall success stories blaming the humans associated with the project instead of the process ;) In one respect that makes all processs arbitary - as long as it's a people root cause under failure and a process root cause under success, you might as well be in a cargocult, or doing witchcraft. Where's the science in that?
That's why I like approaches like TPS and Lean as wrappers around Agile methods - failure, inefficiency, waste are assumed, accepted and objectively worked through (Hansei resulting in Kaizen). It's a people and a process problem.
