Should Change Manager be dedicated? PIR question?

[davidlet]

I am wondering if Change Manager has to be a full time role, per the ITIL v2 book, it is suggesting this role to be full time based so that change review will be addressed properly, but in reality I don't think it is necessary to be a full-timer perhaps IT service manager could do this as part time job. Here, I assume the IT org is not big, and the RFC ticket is not that many...can anyone clarify?

Another question is that PIR is for post change review or before the change application? my understanding is that it should be reviewed in a pre-defined timeframe after the implementation, but someone in the forum said PIR is used before the implementation which is incorrect i think, if it is used before change implementation, i would call it a change testing...is my understanding correct?

Thanks

davidlet,

I don't remember the ITIL books saying that any role has to be full-time and there is even a book (pre v2) that discusses ITIL in a small organization and discusses possibly comfortable combinations of roles.

What you have to do is recognize any potentially conflicting goals between roles assigned to a single person and make sure thy are addressed to protect the interests of the service. It's not terribly difficult so long as you see it clearly.

I hate acronyms. Presumably you are referring to post-implementation review. If so, it seems self-explanatory to me. The review you might hold just before implementing a change would be a pre-implementation review (PIR). Not the same thing atall.

The reality is you do what seems best for you, not necessarily what someone says on the forum. ITIL is guidance not rules. If you understand the guidance you don't need to worry about any rules but the ones you write for your own organization.

Afterthought: you might want to use both and thus have PIR and PIR^.

The scope and time requirements for the Change Manager role should be determined only based on your specific environment.

PIR should be conduct after Change has been implemented... hence the word "Post". Reviewing changes before they are deployed into production can typically take several iterations and involve different stakeholders and groups. Call them peer reviews or technical review, or BA review... sky is the limit.
