The technical service catalogue
This part of the service catalogue holds details of services from an IT
perspective, including a service description in IT terms along with details of the key components or configuration items (CIs) that make up the service and the relationship between them. It describes in technical terms the supporting services listed in the business service catalogue and explains the interrelationships and interdependencies between them. It should also include, if only by cross reference, details of relevant operational level agreements (OLAs) and underpinning
contracts (UCs). It will ideally include information on key personnel who are
either responsible for or provide some kind of technical authority in respect of the service. The technical service catalogue is neither intended for nor usually made available to customers.
As with the business service catalogue, it is easy to put too much detail into
the technical service catalogue. The important point in its design is to have a clear understanding of how the technical service catalogue will be put to use,
remembering that more information generally means a higher maintenance and management cost. Listing all the technical staff who support a service might have some use, but people come and go, change roles, get promoted and so on, and this kind of detail easily gets out of date.
