Configuration Management

Configuration Management

• Objective of case study Configuration Management is to develop CMDB that serves IT support organization, including network service support in the best possible way 
• Every infrastructure component should be linked to a larger system providing a meaning for the existence of the individual component. Systems should be linked to services that they provide for end users
• Choosing the right level of detail for Configuration Items (CIs) is a matter of achieving a balance between information availability, the right level of control, and the resources needed to support it 

Configuration Management – CMDB structure 1/3

CMDB structure was decided to be split into four main categories :
 Group, Service Catalog, Software and Documents

Configuration Management – CMDB structure 2/3

Group: Contains hardware and system CIs, which are organized to office folders according to their actual physical location
Exception was made for workstations, which are placed to country level because automatic scans would require too much administrative work
Folder structure has four levels Group, Region, Country and Office
Service Catalog: Contains the descriptions of IT services offered by Konecranes IT
Service catalog has two levels: Services and Sub-services. Services are more general services that would be easier to understand for end-users
Example: The whole Hyvinkää LAN forms an infrastructure system

The system is placed also in the Hyvinkää-folder in the CMDB
The network components that form the Hyvinkää are linked to Hyvinkää LAN system
Hyvinkää LAN system is linked to the LAN sub-service in the Service Catalog
LAN sub-service is linked to the main service Data communications

Configuration Management – CMDB structure 3/3

Software: Contains the software library for IT software used at case study corporation
Documents:  Contains all CI related documents. For example technical documentation, service descriptions, helpdesk instructions for each service, architectural descriptions and agreements etc.
