Change Control is part of a company’s GMP Quality Management System (QMS) and ensures that the validation of the manufacture, testing, and release of healthcare and pharmaceutical products is not jeopardised through altering and “improving” some of the approved operating conditions.
Throughout the lifetime of a product it is unreasonable to expect a complex series of manufacturing activities to remain unaltered. However, it is equally unreasonable to allow uncontrolled changes to manufacturing process steps, equipment, methods, and specifications to be implemented without due consideration to wider implications, as this may impact on the final product quality and ultimately patient safety.
The change control process is a series of formal assessments of a potential or proposed change, where the initiator details the nature, scope, purpose, and justification for a planned change. This is assessed by all relevant departments and the impact on different areas of the business is determined. Once the full extent of the impact and actions are known a change can be permitted or rejected.
