Conformance
In a quality management system, conformance means producing outputs that stay within the allowable range of variation defined for a specific quality requirement.
Key Points
- Focuses on meeting specified tolerances rather than exceeding requirements.
- Acceptable variation is defined by quality metrics, specifications, and control limits.
- Verified through inspections, testing, measurement, and quality control checks.
- Nonconforming results trigger corrective action, potential rework, or change requests.
Example
On a construction project, concrete must achieve 4000 psi strength with a tolerance of +/- 5%. Test results between 3800 and 4200 psi are considered conforming. Batches outside this range are nonconforming and require rework or rejection per the quality plan.
PMP Example Question
Which situation best demonstrates conformance in a quality management system?
- Project reports consistently stay within the tolerance bands defined by the quality metrics.
- The team adds extra features to delight the customer without an approved change request.
- The project manager demands zero variability by requiring every output to hit the exact target value.
- The team rejects all items that are slightly outside the nominal value, even if within the specified tolerance.
Correct Answer: A — Meeting defined tolerances
Explanation: Conformance is about delivering results that fall within the acceptable limits of variation set by the quality requirements; option A reflects that.
