HighCeremonyMethod is a characterization MartinFowler used in UmlDistilled for SoftwareProcesses with lots of formal meetings, FormalReviewProcess, FormalTesting, artifacts (see YouArentGonnaReadIt), etc.
[Please note that Martin Fowler, though deserving of much respect and credit for lightweight methodologies, is still not the final word in process methodology. A grain of salt here, people. The same note applies to all discussion of methodology here on the C2.]
