Change control is one of the most critical pillars of pharmaceutical quality systems. Whether the change involves equipment, raw materials, documentation, processes, utilities, or computerised systems, every modification must be evaluated, justified, and implemented in a controlled manner. For quality teams and students pursuing the Quality Assurance and Quality Control Diploma, mastering this process is essential for ensuring compliance, product integrity, and patient safety.
This step-by-step guide breaks down the core components of a compliant and effective change control workflow used throughout the pharmaceutical industry.
Step 1: Initiate the Change
A change begins with a clear, well-documented request. This includes describing what needs to be modified, why it is necessary, and identifying the potential scope.
At this stage, teams gather background information, reference current procedures, and ensure the change aligns with regulatory and operational expectations. Strong documentation is key from step one in this process.
Step 2: Conduct a Quality Impact Assessment
Before approving any modification, organisations must determine whether the proposed change could affect product quality, safety, identity, strength, or purity. A quality impact assessment examines upstream and downstream processes, equipment interactions, and batch release implications.
This step often requires cross-functional collaboration. Quality, production, engineering, validation, and regulatory teams may all contribute insight to ensure the assessment covers every possible impact.
As explored in the AAPS Quality Assurance program, impact assessment examines processes.
Step 3: Perform a Risk Assessment for Manufacturing Changes
Once impact is established, teams move into a structured risk assessment for manufacturing changes. The goal is to identify potential failure modes, analyse their likelihood and severity, and determine risk mitigation strategies.
Tools such as FMEA, Ishikawa diagrams, or hazard analyses help teams visualise risks and prioritise controls. The assessment determines whether the change requires validation, additional monitoring, or enhanced testing before full implementation.
Step 4: Approve and Plan the Change
After the risk is evaluated, the change control board or designated quality authority reviews the proposal. Approval criteria include compliance readiness, resource availability, technical feasibility, and completeness of the plan.
At this stage, teams create a detailed execution strategy outlining:
- Required documentation updates
- Validation or qualification activities
- Training requirements
- Timelines and responsibilities
- Success criteria
As highlighted in our Quality Assurance Training in Ontario, a well-structured plan prevents disruptions and ensures consistent execution.

Step 5: Implement the Change
Implementation begins only once approvals are final. Activities may include equipment installation, updating batch records, modifying SOPs, performing validation runs, or training staff. It is essential to document every action taken within manufacturing records and quality systems.
Clear communication helps avoid unplanned downtime or deviations during this phase.
Step 6: Conduct a Post-Implementation Review
When the change is complete, a post-implementation review verifies that expected improvements were achieved and that no unintended consequences emerged. Teams review process data, deviation reports, CAPA trends, and batch outcomes.
If the change performs as planned, documentation is finalised and archived for future audits. If issues arise, corrective actions or further adjustments may be required before officially closing the change.
Quality Control Training in Ontario emphasizes verifying that expected improvements were achieved.
