Since ITIL does not tabulate all the role definitions anywhere, not even the glossary (except possibly on the ridiculously expensive ITIL Live - who'd know?), once again the IT Skeptic provides a public service in the same way as our cross-reference list of ITIL V3 processes. Here is

the IT Skeptic's Unofficial Unauthorised List of ITIL V3 Roles

[Updated 2009/4/16: added SFIA cross reference and some questions]
[Updated 2009/10/7: added five more roles - thanks JRD! "By far the best list I've found!"]
[Updated 2009/10/23: added comments about the Glossary]

In the ITIL ref column: SS=Service Strategy (book), SD=Service Design, ST=Service Transition, SO=Service Operation, CSI=Crime Scene Investigation
the numbers refer to sections in the book.

In the SFIA column, the four-character codes refer to SFIA skills. See SFIA for de-code.

....but wait! I only count about 15 or 16 process managers in there and zero process owners.

ITIL tells us that every process has an owner so add another twenty-something owners (depending on who is counting the ITIL processes).

Does every process have a Manager role? ("There may be several Process Managers for one Process... The Process Manager Role is often assigned to the person who carries out the Process Owner Role, but the two Roles may be separate in larger Organisations.") If so there are another ten-or-so manager roles to be added to this list too.

That would bring us to about 90 roles in ITIL V3.

Keep in mind that these are roles not headcount positions. Sometimes they are more just actors (e.g. SS) than formalised roles (e.g. SD) - ITIL does not distinguish. I left out some that were clearly an actor, e.g. "Customer" or "Application Service Provider"

The mapping from roles to SFIA isn't good as skills are not the same thing as roles. Suggestion welcome for other role models to map to.

Questions:

1. Is the SS Product Manager different from the CSI Service Manager?
2. Are the ST and CSI "Service Owner" roles the same thing? The books don't cross-reference each other
3. The glossary definition of "Service Manager" bears no resemblance to CSI Service Manager. SS's Product Manager isn't in the glossary at all. In fact most roles aren't.
4. Why does SFIA recognise "Software Development Process Improvement" but not CSI? (although it recognises the other four ITIL V3 books)
