Key Points
- Used to confirm that outputs meet written standards, specifications, or requirements.
- Can occur at receipt, during execution, or before final acceptance.
- Often uses checklists, measurements, and sampling to detect defects.
- Results may trigger acceptance, rejection, rework, or updates to the defect log.
Example
The quality engineer examines completed wiring panels against the project specifications and safety codes, using a checklist to confirm labeling, torque settings, and component ratings before authorizing installation sign-off.
