Good morning,

I am currently trying to analyse the amount of effort, in man days, for implementing a ChM process across our organisation. I have broken down ChM using the mapped COBIT control objectives, to show some of what is involved in ChM. Although I can make an educated estimate of how much time would be involved in, say, putting together the policy and procedures, I am struggling with getting my head around how I would show the amount of effort involved in a BAU task such as approving or reviewing a change. I understand that this would obviously be different for every organisation, but I was just wondering if anyone has any ideas, or has done similar?

Thanks in advance,
Davey

It takes as long as it takes

As I have done this thrice and since I know CoBIT

120 man hours to search t he company gather data for writing the policy, process procedures et al this include doing thing like seeing twhat is done currently in incident/problem etc
40 man hours to draft a policy - first draft
80 - 120 hours - 2nd draft to include get comments from senior people
20 - 4 man hours on presentation and other road show work
40 - 80 man hours final draft

I gave my self 3 months to get this done

Thanks for your response John. I had currently allocated the following: -

Change Standards and Procedures - 45 man days
Impact Assessment, Prioritisation and Authorisation - 15 man days
Emergency Changes - 10 man days
Change Status Tracking and Reporting - 10 man days
Change Closure and Documentation - 5 man days

This adds up to just under 3 months, so seems to tie in well with what you said.

To put the process together and implement it, yes. I took that to be what your post also suggested. Apologies if I have misread.

Also, I have broken each area down in to the ammount of effort required by me and by my IT colleague who I will need to work with. There are no business inputs at the moment. For example, the 45 man days for Change Standards and Procedures is split as 36 days for me and 9 days for IT.
