Brief Description
The Installation Qualification (IQ) Protocol for the Automatic Capsule Filling Machine is prepared to confirm that the machine has been properly installed according to the approved design and manufacturer’s requirements. It describes the machine, its major components, utilities, safety features, calibration requirements, material of construction, drawings, documents, and related SOPs. The protocol also includes an installation checklist to verify electrical connections, equipment anchoring, identification, wiring, and servicing space. The machine has production and non-production zones with systems for capsule loading, powder/tablet filling, rejection, locking, ejection, and cleaning. Required utilities include three-phase electricity and compressed air. Safety features such as emergency switches, door interlocks, pressure interlocks, and password protection are identified. Any deficiency is documented with corrective action. After completion, the IQ data and discrepancies are reviewed, and the final report is approved by Production, Engineering, Quality Assurance, and Head Operations.

1. Brainstorming:
The brainstorming diagram identifies the possible reasons why Installation Qualification (IQ) for the Automatic Capsule Filling Machine was not performed. It organizes potential causes under key areas such as Documentation, Team & Responsibility, Verification, Utilities & Safety, and Planning & Compliance. Major concerns include pending protocol approval, unclear responsibilities, poor coordination between QA, Engineering, and Production, non-execution of the installation checklist, incomplete verification of major components, utilities, safety features, calibration requirements, material of construction, and supporting documents. It also highlights planning gaps, schedule pressure, missing SOP identification, and failure to prepare deficiency reports and the final IQ summary.
The brainstorming approach helps the investigation team collect and classify possible causes before selecting the most probable root cause. This supports a systematic deviation investigation and helps define appropriate corrective and preventive actions to ensure the capsule filling machine is properly installed, documented, and qualified before routine GMP use.
2. 5 Why Analysis:
The 5 Why Analysis was performed to identify the underlying reason why the Installation Qualification (IQ) of the Automatic Capsule Filling Machine was not performed. The analysis starts with the immediate issue—the IQ protocol was not executed—and then progressively examines why the approved protocol was unavailable, why its review and approval were delayed, and why the required supporting documents were not prepared on time. The analysis ultimately identifies inadequate project planning and poor coordination between Engineering, Quality Assurance, Production, and other stakeholders as the likely root cause. This resulted in delayed preparation and approval of the IQ protocol and, consequently, failure to execute the qualification activity at the required stage.
The uploaded IQ protocol specifically requires an approved protocol, defined responsibilities, execution by a multidisciplinary team, installation checks, document verification, and final review/approval. This 5 Why analysis helps support appropriate CAPA, responsibility assignment, scheduling, and stronger qualification controls.
3. Impact Assessment:
The Installation Qualification (IQ) of the Automatic Capsule Filling Machine has an important impact on the safety, quality, and reliability of capsule manufacturing. The IQ confirms that the machine is installed correctly as per the approved design, manufacturer’s requirements, and GMP expectations. Proper verification of major components, electrical connections, compressed air supply, safety features, calibration requirements, and material of construction helps reduce the risk of equipment failure and product quality problems. The identified safety features, such as emergency switch, door interlock, vacuum pressure interlock, air pressure interlock, and password protection, help protect the operator and batch. Any installation deficiency or discrepancy is recorded and addressed through corrective action. Completion of IQ provides documented evidence that the machine is suitable for further qualification activities. Therefore, successful IQ has a positive impact on equipment performance, operator safety, product quality, and GMP compliance. The machine can proceed to the next qualification stage after approval of the IQ report.
For the Automatic Capsule Filling Machine, the uploaded IQ protocol does not specifically define CPPs and CQAs. It does, however, identify the machine functions, major components, utilities, safety features, and calibration requirements that can affect capsule filling.
