Configuration management is about collecting and maintaining useful information. In IT service management (ITSM), this means knowing about everything from hardware and software through to documentation and people – all of which is used to deliver services. We collect and hold data about those items, including information on how they are connected together.
Configuration management itself is way older than ITSM, with its roots firmly in old-fashioned engineering. Although we don’t know the equivalent term in Ancient Chinese, Egyptian, or Mayan, I guarantee that configuration management was being done in those times. They all must have understood the principles in order to get the Great Wall, the Pyramids, and Stonehenge right. And those creations look relatively simple compared to the bridges, ships, and railroads that mechanical and civil engineer Isambard Kingdom Brunel and his successors were building – and crucially also maintaining – in the 19th century.
