Paul,
I have created methodologies for companies around the world and I usually start the discussion from my website and in particular my methodology site (http://home.comcast.net/~projectmgmt). I have worked with Method1, RUP, and other methdologies throughout the years and have observed the following:
1) Most methdologies are created at a much higher maturity level than the current company maturity level (yes, you can teach quantum physics to 3rd graders...but why?)
2) Most are too complicated. I have a very easy quick reference guide I have used over the years to help define your process (phases), define roles, define the success criteria for each phase, define activities normally taking place during the phase (with flexibility to account for the unseen), and define deliverables. I don't like to give a company 50 templates when 15 will do with the flexibility to have others to make work easier. If a project team member needs a Phd. to follow a methodology, you are defeating the purpose of the methodology. It should be a guide to increase the efficiency of delivery, not a hinderance.
3) Many are aimed at the wrong audience. The methodology should help the team perform, not serve as a source of negative reviews from management. It should be a guideline for success, not a benchmark for negative actions or appraisals.
If purchased or built in this light, it can be a great experience.
