Base Model
- Consider five size categories for all IT projects: Extra Small, Small, Medium, Large, and Extra Large. (ed. This is one or two more categories than prior art I have discovered so far – sml)
- "Size" means the complexity and risk as impact on the end-user community.
- The Size Category determines the release processes that must be followed. That is the sole purpose of this tool.
- Determine sizing score by considering a concrete set sizing criteria, or decompositions. (ed. Decomposition of Risk, PMBoK – sml)
- Still figuring out if these should be summed, averaged, or some other math.
Phases
- If you can break a project down into discrete phases of lesser impact, you can reduce the amount of required process and complexity.
- A "phase" is only a phase if it can result, on its own, in a discrete improvement to the product or service.
- You can reduce scope by eliminating non-dependent phases.

I found some tid bits on Wikipedia in the ITIL section that may or may not be helpful (high level)
Release categories include:
Major software releases and major hardware upgrades, normally containing large amounts of new functionality, some of which may make intervening fixes to problems redundant. A major upgrade or release usually supersedes all preceding minor upgrades, releases and emergency fixes.
- Minor software releases and hardware upgrades, normally containing small enhancements and fixes, some of which may have already been issued as emergency fixes. A minor upgrade or release usually supersedes all preceding emergency fixes.
- Emergency software and hardware fixes, normally containing the corrections to a small number of known problems.
Releases can be divided based on the release unit into:
Delta Release: a release of only that part of the software which has been changed. For example, security patches.
- Full Release: the entire software program is deployed—for example, a new version of an existing application.
- Packaged Release: a combination of many changes—for example, an operating system image which also contains specific applications.
