Defining the service model

After you have decided on a business goal for service impact management, decomposed your business processes, and created a service catalog, you are ready to define the actual service model.

Defining the service model involves establishing a list of all the IT resources that must be represented in the service model. This information must include the following details:

• The name or component identification pattern of each resource
• Its location or site

You can use this information later in the design phase and when creating service model components or CIs.

The first step in developing a service model is to design its logical architecture. To do this, you must analyze the IT environment and identify the following details:

• Resources that constitute the service model
• Event sources for the resources and their characteristics
• Functional relationships and dependencies between various resources that can affect services
