Raiseaticket Change Management provides a structured process for planning, reviewing, approving and implementing operational or IT changes - so that work which could affect a live service is agreed and recorded before it happens rather than explained afterwards.
Changes can be linked to incidents, service requests and affected configuration items. That traceability is the part that pays off later: when something breaks, the question is almost always "what changed?", and the link between the incident and the change that preceded it is what answers it.
Because unplanned change is a common cause of incidents, and because approval that happens in conversation cannot be reviewed afterwards. Recording reason, risk and rollback in advance forces the thinking to happen before the work, and leaves a record that stands up when someone asks who agreed to what.
No. Change management is a premium add-on. The free plan covers the helpdesk itself; change management sits alongside asset management as capability for internal IT teams running services rather than answering customer questions.
