What are the components of a quality system inspection technique (QSIT)?

The FDA's QSIT focuses on evaluating four major subsystems of a quality management system:

1. Management Responsibility
   Assesses leadership's role in quality, including setting policies, assigning responsibilities, allocating resources, and conducting management reviews.

2. Design Controls
   Evaluates the adequacy of product design processes to meet user needs and regulatory requirements. Includes design inputs, outputs, reviews, verification, validation, and transfer.

3. Corrective and Preventive Actions (CAPA)
   Focuses on processes for identifying, investigating, and resolving quality issues. This includes root cause analysis, implementing corrective actions, and verifying their effectiveness.

4. Production and Process Controls
   Reviews manufacturing controls like process validation, equipment maintenance, material management, and environmental conditions to ensure consistent product quality.

What is a QSIT inspection?

A QSIT (Quality System Inspection Technique) inspection is an FDA methodology for assessing compliance with the Quality System (QS) regulation (21 CFR Part 820). It evaluates how well a manufacturer’s quality system functions, focusing on key processes within four subsystems:

1. Management Responsibility
2. Design Controls
3. Corrective and Preventive Actions (CAPA)
4. Production and Process Controls

Unlike a checklist, QSIT uses a hierarchical, process-based approach. Inspectors assess interconnections between subsystems, selecting processes to audit based on risk and the firm's history. This systematic method ensures that the quality system is effectively implemented and meets regulatory requirements.
