Configuration Management explained
Configuration Management is often thought of as the key process with the ITIL framework. It is a critical process without which the effort involved in establishing and maintaining the other processes is largely negated.
Configuration Management includes the identification, recording and reporting of (all) IT components and the relationships between them.
The definition highlights the critical element of understanding relationships between Configuration Items. Through understanding CI relationships we have a much higher chance of understanding the impact of failure of a CI (incident and problem) as well as the potential negative impact of change to a CI.
Incident, Problem and Change Management are therefore, highly operational processes that benefit from a well defined Configuration Management process.
