SSG 14: Configuration Management

Version 1.0 April 2019

What can an organisation do to get the best out of its assets? Some assets can be configured in multiple ways, and these configurations can vary over time. This creates operational, maintenance, planning and supply chain challenges but to name a few. Configuration management identifies, records and manages the functional and physical attributes of assets, software and related documentation including the links between the components of a system. It is integral to asset creation and acquisition and is closely aligned with the principles of systems engineering.

This SSG covers the 5 key elements of configuration management:

Configuration management and planning
Configuration identification
Configuration control
Configuration status accounting
Configuration verification & audits
