Using DQ/IQ/OQ/PQ in a New Model
Apply DQ/IQ/OQ/PQ
DQ, IQ, OQ, and PQ refer to Design Qualification, Installation Qualification, Operational Qualification, and Performance Qualification, respectively. These terms can play a vital role in validation processes in different fields today. Here is a short guide on how to implement them using the new model.
Design Qualification (DQ): DQ enables the determination of whether the equipment or system design is appropriate. It consists of an examination of design specifications, functional requirements, and legal requirements. It is necessary to confirm that the design meets the standards and satisfies the end users.
Installation Qualification (IQ): The Installation Qualification stage consists of confirming that the equipment or system has been installed the right way per the manufacturer’s specifications and recognized best practices in the industry. The process checks the placement of the equipment, connections and utility supplies, and calibration and alignment of the equipment. During this stage, the installation is documented as per the requirements put forward during the process.
Operational Qualification (OQ): In this stage, the process is aimed at confirming the effectiveness of the equipment or system in functioning. This includes conducting performance and operation tests, carrying out mock operations, as well as checking the critical operational parameters that are critical. During this process, data should be collected, adjustments made, and results recorded.
PQ – Performance Qualification: PQ tests how well the equipment or system performs during real operation. This means that PQ is about testing whether the equipment can give consistent results within specified parameters. Conduct tests, collect the results, perform the analysis, and document the results.
In order to implement the DQ/IQ/OQ/PQ in a different way, it is essential to create a full Validation Plan. Collaboration with all the concerned parties such as producers, QA departments, and governmental bodies is needed in order to ensure compliance with regulatory requirements. Records of validation activities and their protocols, results, and corrections undertaken should be kept.
Moreover, regular audits and revalidations must be conducted when required.
