SQA SQA Validation and Qualification 3

Question 1

What is 'concurrent validation' and when is it typically used?

Accepted Answer

Validation performed during routine commercial production, used when limited batches are available due to rare products or urgent medical need

Answer

Validation studies that run in parallel with prospective validation activities

Answer

Validation of two different processes or products being run simultaneously

Answer

Validation performed simultaneously across multiple manufacturing sites

Question 2

What is the purpose of a Validation Summary Report?

Accepted Answer

To document all validation results, confirm acceptance criteria were met, and provide a conclusion about the validated state of the system or process

Answer

To plan all future validation activities for the upcoming year's schedule

Answer

To list all equipment requiring qualification in the facility prioritized by risk

Answer

To report significant validation deviations directly to regulatory agencies

Question 3

What is Design Qualification (DQ) in equipment or system qualification?

Accepted Answer

Documented verification that the proposed design of a facility, equipment, or system is suitable for its intended purpose

Answer

The first phase of operational testing performed after equipment installation is complete

Answer

A review of equipment engineering drawings conducted by the internal engineering team

Answer

A supplier audit performed to verify the manufacturer's quality during fabrication

Question 4

In analytical method validation, what does 'linearity' refer to?

Accepted Answer

The ability of a method to produce results directly proportional to the concentration of analyte within a defined range

Answer

The ability of a method to detect very small differences in concentration between samples

Answer

The consistency of results produced when the same sample is tested multiple times

Answer

The method's freedom from interference by co-eluting or overlapping chromatographic peaks

Question 5

What is 'Continued Process Verification' (Stage 3 of FDA's process validation lifecycle)?

Accepted Answer

Ongoing monitoring of process performance during commercial manufacturing to ensure the process remains in a validated state

Answer

Executing the required third batch of a prospective validation study

Answer

Annual re-execution of all process validation protocols to confirm continued compliance

Answer

Periodic audits of the manufacturing process conducted by the internal quality team

Question 6

What does a 'risk-based approach to validation' mean in pharmaceutical practice?

Accepted Answer

Directing validation effort toward systems and processes with the greatest potential impact on product quality and patient safety

Answer

Eliminating validation requirements entirely for processes classified as low risk

Answer

Performing the absolute minimum validation required to reduce costs and timelines

Answer

Using only automated testing tools for all validation activities to reduce human error
