All Information
The terms Validation and Verification are often confused, especially in management systems such as food safety (HACCP). Both processes are critical in ensuring the effectiveness and reliability of any management system.
- Verification: Ensures planned tasks are being performed as intended.
- Validation: Scientifically proves that processes achieve their intended goals under real-world conditions.
Both processes are essential for a robust management system and high production efficiency.
Validation
Validation confirms through scientific evidence that a process or step effectively achieves the desired outcome.
Example:
For a metal detector in a food production facility, validation involves:
- Performing periodic maintenance and calibration tests to ensure the device works efficiently.
- Training staff to operate the device and ensuring their competency.
- Ensuring product characteristics (e.g., size, density) align with the detector’s capabilities.
- Documenting all steps with evidence such as calibration certificates, training records, and test results.
Validation answers: “How does it work?”
Verification
Verification ensures that activities and processes are being executed as planned.
Example:
For a metal detector in a food production facility, verification involves:
- Using test samples containing specific metal sizes to ensure the detector triggers an alarm.
- Checking periodically if the detector functions as intended.
Verification answers: “Does it work?”
