using ISO20000 to start off ITIL

[zoe]

Folks I am just starting on a long road to implement ITIL or at least some of ITIL. My analytical mind told me to benchmark where we are now and try and define the gaps. I bought the BSI ISO20000 workbook / assessment with the view of benchmarking the as it is position.

I have just got my hands on the work book.

Looking at the first two sections chapter 3 and 4 which are
requitements for a management system and
the PDCA cycle / stage.

The guide says I need to carry out these baseline activities against each process.

considering my purpose and where the organisation is at the moment I don't see much point in carrying out these assessments on a framework that currently doen't have a formal defintion.

I would instead like to dive into chapter 5 planning and implementing new or changes services. Because this can be generic against the general change management. chapter previous 3 and 4 need a specific process.

I think it would be appropriate to review the implementation of ITIL process using chapters 3 and 4 after I have implemented something to audit.

Any thoughts on this logic please?
