There are cases where you can achieve success with a tactical implementation of a service request catalog.
If your company is small enough, and you set your
expectations appropriately you can get a tactical service request catalog project to work; particularly if it's a small deployment to your
IT staff. For example, the storage team may deploy a service request
management tool for requests from the application development group. This would be a sensible small project. Keep it small enough and you can get some success; the issue I've seen is that the ROI is not there, so it's hard to get funded.
The other way to succeed is to keep the catalog wide but super simple. Here are a few tips:
- Use a tested accelerated deployment methodology. If you don't have to invent it, it will save you a lot of time. Your vendor should have one or your consultant.
- Use standard, pre-packaged content. This saves you from the laborious effort of creating descriptions, pictures, forms, data models, messages, portals, etc, etc.
- Keep complex scripts out of the first roll out. This enables you to use lower cost internal resources to maintain the catalog.
- Don't touch or change back end workflow. In fact, it's easier if you don't integrate with the existing stuff. You can always do that later. This issue is even true for the "pre-integrated" vendors; the catalog products are separate enough from the back end that you end up with a field mapping exercise along the way, error messages, etc, etc. Lots of discussion about the types of issues all over the net.
In other words, the faster and cheaper you go, the more likely you will succeed. The problem with this approach is that it's not really doable at the Global 2000 enterprise level. But it's doable in smaller organization, or divisions.
Finally, as you evaluate your catalog software vendor, you ought consider this:
When I'm ready to expand the scope of my request management deployment,
will they scale with me - or will I need to migrate to another enterprise-class
product?
When we are ready to do a Service Catalog compatible with ITIL V3,
will it get me there or do I need to throw out all my work? Can the service request definitions be used as components of my service portfolio to drive consumption and cost visibility?
