Service Assets and Configuration Management
Overview of Assets
Asset is something that has financial value with a depreciation rate attached to it. It has a cost and organization uses it for its asset value calculation.
It does not have direct impact on delivering services. Anything such as servers, buildings, blackberries, switches, routers etc. comes under assets.
Configuration Items (CIs)
Configuration item is a subset of service assets and have direct impact on delivering services. All servers, networks, applications that have impact on production are known as configuration item.
Building is an asset but not CI. Document is a CI not an asset.
Hence Service Assets and Configuration Management (SACM) deals with maintaining up-to-date and verified database of all assets and CIs which are also made available to other service management processes.
Configuration Manager is the process owner of this process.
SACM uses Configuration Management System (CMS) which contains one or more Configuration Management Databases (CMDB).
CIs are categorized into six as shown in the following diagram −

Organization CIs are internal to an organization but independent of the service provider.
CIs which are delivered by individual projects are known as Internal CIs.
External CIs refer to external customer requirements and agreements, releases from supplier and external services.
These CIs are required to deliver end-to-end service across a Service Provider Interface (SPI).
