In 30+ years of contracting and developing stuff ... I have never worked on a project where any one system at any organization was used 100% ... we basically used Hybrid methodologies (Waterfall, Agile, Prince 2, etc.) ... and never focused on doing a project in any certain way the whole way through to delivery ... we worked in various roles and did what we had to do to get some system completed.

We have always started out on some Waterfall method to document the major requirements, business rules, visions and understandings and then worked on the project from there ... Team and Project methodologies, which usually varied.

You might be interested in a new, fully-reusable design paradigm / patten / framework, I call Interaction Profiling.  Check out my BPM.com article at this link.  I really do believe it can save large Corporations literally millions in both development and maintenance costs.  I admit being somewhat biassed, as the designer of the technique, but I have developed a fully functoinal prototype that really does substantiate my cost savings estimates.  You can also check out my web site, MidlandMicro.com, if you have the time and sufficient interest after reading through the BPM.com post.  All of the design details are presented there.  Enjoy!  ;)
