Change control is the system that makes sure changes to facilities, equipment, processes, materials, suppliers, specifications, documents and computerised systems are evaluated before they happen. A change request describes what will change and why; a multidisciplinary review assesses the impact on product quality, validation status, regulatory filings, documentation and training; and QA approves or rejects it.
Once approved, the change is implemented through defined actions — updating SOPs, retraining staff, revalidating equipment, notifying regulators where needed — and each action is verified. A post-implementation review then confirms the change achieved its purpose without unintended effects.
Why it matters in GMP
ICH Q10 names change management as one of the four elements of the pharmaceutical quality system, and EU GMP, WHO GMP and Revised Schedule M all require a formal change control system. Uncontrolled changes are a frequent root cause of deviations and a common inspection observation.
- Classify changes by risk so effort matches impact.
- Check the impact on validated systems, documents, training and regulatory filings.
- Track every action to closure with evidence.
- Review effectiveness — not just completion.
How Swat iQua Suite handles it
Swat iQua Suite gives change control the same four-person chain as deviations — initiator, reviewer, approver and decision-taker must all differ — with an optional per-site e-signature on approval. Change actions are verified by someone other than their owner, extension requests can only move dates forward, and a hard overdue gate stops late actions being verified without an approved extension. After closure, an effectiveness review is carried out by someone other than the initiator.
