What is a “Service Catalog”? Ask this question to 10 people and y0u may get 20 answers. And the answers vary from a documented resume-like list of IT capabilities to a list of requestable items that IT can provide to an end-user. As IT vendors and consulting organizations, we’ve done nothing but contribute to the overall confusion around the service catalog. The only thing we’ve been able to convey with any consistency is that if you are an IT service provider (whether internal to an organization or an external third party) it’s important to have one. That’s were the common theme around service catalog ends, I’m afraid.
So let’s break it down from an ITIL perspective:
Question 1: What is a Service?
A service is something that provides “value” to customers by facilitating outcomes customers want (an email service that is up and running 24 x 7 with the ability to send and receive messages, filter spam and guarantee deliver – or pick another customer facing service where you can clearly articulate a desired business outome) without the specific ownership of costs or risks (because the customer is not a technology expert, they are a subject matter expert for their business area…this does not mean that they don’t pay for the service…it means that as the technology expert The IT service provider has a better opportunity to understand and control the costs and risks than they can hope to…therefore they’ve put the ownership of this in your more capable hands).
Question 2: What is a business service and what is an infrastructure service?
A business service is an IT service that DIRECTLY supports a business process. Benefits Administration for example is a business service that allows the a business unit to track and manage corporate benefits, benefit entitlements and the subscription choices of employees. In a water delivery system, think of the faucet being the business service. When I turn the cold water faucet on I get cold water. When I turn the hot water faucet on I get hot water.
An infrastructure service is an IT Service NOT DIRECTLY used by the business, but is required by the IT service provider so that they can provide business services. For example, in order for the Benefits Administration Business service to perform it’s required functions it needs to be supported by server administration services, storage services, directory services, or communications services. Think of the infrastructure services being the plumbing and the water heater in your home and the wells, or reservoirs, pumping stations and the municipal piping that deliver water to your home.
Question 3: What is a Service Catalog?
A Service Catalog is a database or structured document with information about all Live Service or services planned for delivery. It is used to support the sales and delivery of IT Services. The Service Catalog includes information about deliverables of IT Services, contact points, prices, ordering and request processes. The portion of the service catalog that is visible to business customers are only the Business Services. Both Business and Infrastructure services are visible to the IT organization.
Question 4: What is a Service Request?
A Service Request is the action of subscribing to a service or turning on, off or altering some underlying aspect or capability of a service. For example, if Email is my business service I may be able to make the following requests:
- Add or remove mailbox
- Add or remove a mail user
- Grant or restrict rights to access a mailbox to a user
- Extend the amount of space in a mailbox
Question 5: What is an Actionable Service Catalog?
It is an electronic version of the Service Catalog described in Question 3, constructed in such a way to allow you to search services, service levels, service contacts, make requests related to services. It provides both a communication vehicle (linking realtime service level metrics, or alerts to service changes, for example) and an automated service request mechanism to allow for self-service.
