Validation and Qualification of Equipment
Start with the big picture
Qualification is a type of validation focused on equipment, systems, and facilities: it provides documented evidence that they are installed and function correctly before production use. Validation addresses whether a process consistently produces results meeting predetermined specifications and quality attributes. The lesson follows the equipment-qualification lifecycle, from the Validation Master Plan (VMP), which sets scope, approach, schedule, and responsibilities, through qualification and recordkeeping to ongoing control. It also introduces regulatory expectations and explains why calibration, maintenance, testing, and requalification matter. Requalification or revalidation may be needed after critical changes or at time-based intervals. Together, these practices help maintain reliable equipment performance and reduce the risk of batch failures and related quality consequences.

- Identify DQ, IQ, OQ, and PQ as the four qualification stages.
- Explain the purpose of a Validation Master Plan.
- Describe the role of documentation, calibration, maintenance, and testing.
- Recognize when requalification or revalidation may be needed.
