Peeling Back the Service Catalog
I’ve written several times about the service catalog. It’s one of those things that is as powerful as it is confusing. Developing a service catalog is an evolutionary project. As with any project that should be done in phases, where you start depends upon what your needs are.
Let’s start by looking at the benefits of the service catalog:
- Do you have a pressing need to understand the impact to services when an infrastructure or application change is made?
Prioritize your inventory by first capturing services that underpin business processes. You will not get the complete picture of how a change to infrastructure or an application affect a business service until you’ve built a service relationship model within a CMDB and can capture the service components end-to-end, but at this step you should be capturing business owner, business criticality – which can be helpful in determining the risk of the change or the prioritization of an incident. - Do you want to facilitate a common understanding of services with your business communities?
Expose the catalog of services to the business with the following attributes captured:
- Service Description
- What’s included with the service
- Hours of Operation
- Critical Operating Windows
- Service Costs (optimally at a level of granularity where, when possible, the customer is able to influence that cost by controlling number of users or utilizaiton).
- Service Levels – what can the business or end user population expect for availability, performance, response time on incidents or response time on requests.
- Are you trying to provide an easy, predictable mechanism for your end users to get standard requests fulfilled?
You’ll want to work on a Service Request Catalog which allows for data collection, and approval and fulfillment methods that are underpinned by service levels to the customer and internal operational level agreements.
Determine where your priorities lie to understand the right approach. The catalog can be a powerful tool when implemented correctly!
