I can definitely endorse this point of view. I've had success with it a number of times now. I think part of the key here is to recognize that you are working on a project (including managing it) in service of those that will consume the results. The mistake I often times see is that people forget that and end up in service of one methodology or another. Too many times I see a project manager types that can't reason out the distinction between the mechanics of a given project management process and the goal that process is setting out to achieve through the mechanics. Once you focus on what you're trying to achieve in any process, rather than how you're trying to achieve it, you can adjust your process to be optimal to the team/customer/etc. It's not all mutually exclusive and there are rarely benefits for being loyal to a methodology for purity's sake.
