Definition
Change control provides a defined workflow for evaluating proposed changes before they are implemented. It typically includes impact assessment, responsibilities, approvals, implementation activities, required updates and closure evidence. In regulated environments it helps prevent unintended consequences.
Why it matters
Change control matters because even necessary changes can create unintended effects on products, processes, documentation, training, validation or compliance. A formal review and approval process helps identify those impacts before implementation.
Capture the reason, affected item or process, intended outcome and enough context for reviewers to understand the request.
Describe the proposed change
1
Evaluate effects on quality, compliance, documents, training, validation, suppliers, systems and other controlled processes before approval.
Assess impact and risk
2
Route the change to the relevant decision-makers and document the approval, conditions or rejection.
Review and approve
3
Complete the approved tasks, update controlled information and coordinate communication or training needed for the new state.
Implement controlled actions
4
Confirm that the intended change was implemented correctly and that required evidence or dependent actions are complete.
Verify implementation
5
Record the effective state, final evidence and links to affected records so future audits or investigations can reconstruct what changed and when.
Close with traceability

Process explained
Controlling change from request to closure
Change Control provides a disciplined path from proposed change to approved implementation. The process should show what is changing, why it matters, who assessed the impact and whether documents, training, validation or follow-up are needed before the change is considered complete.
A structured process for evaluating and controlling safety, operational and compliance risks before significant technical, organizational or process changes are implemented.
