I am kind of in the same position as you, although I have been using otrs in production for abt 1 year now.
 
The question you ask is (i think) one of the 10 "Dont's" in anty ITSM implementation, but for the case of otrs+itsm I see no problem with implementing the following;
 
Ticket system, no problem.
Catalog Items, no problem.
 
The servives and location, I would wait with, to get an clear view of how to implement.The way otrs itsm works, is that you mainly make manual links between different objects, so you will always be able to link up to the different services and locations at a later time.
 
 
good luck!

Subject: [itsm] Where to start ?


Hi,

I've been searching about for an open source cmdb for a while, and I'm also looking to switch to a decent helpdesk/ticketing system.

I've been playing with OTRS for a few weeks and then I see ITSM is released.

Great, I'm keen to get started.
Where do I start ?

Do I define locations first, or services, or computers and hardware ?
It would seem that getting it wrong during design will be something I'll regret.

I need OTRS right now, so I can't wait to learn the nuances of ITSM.
If I deploy OTRS and research ITSM on a separate system, will I be able to add my ITSM to my existing OSTR later ?

Can anyone offer some advice ?

Thanks
