How to write an effective nonconformity statement

Quality auditor with a clipboard on site
In short: An effective nonconformity statement has three parts: the requirement, the objective evidence observed, and a clear statement of how the evidence fails to meet the requirement. It should be factual, concise and understandable without the auditor present.

What are the three parts of a nonconformity?

  1. Requirement — the clause, procedure or contract condition
  2. Evidence — what was seen, heard or reviewed, with references
  3. Statement — how the evidence does not meet the requirement

What is an example?

Requirement: Procedure QP-07 requires calibration of all measuring equipment every 12 months. Evidence: Micrometer M-114 in Cell 3 was last calibrated 18 months ago (record CAL-2021-044). Nonconformity: Measuring equipment was not calibrated at the defined interval.

What should auditors avoid?

  • Opinions and vague words such as “poor” or “inadequate”
  • Recommending solutions in the finding
  • Findings without traceable evidence

Key takeaways

  • Use requirement, evidence and statement.
  • Be factual and specific.
  • Let the auditee own the solution.

Frequently asked questions

What is the difference between a major and minor nonconformity?

A major nonconformity affects the system’s ability to achieve intended results; a minor one is an isolated lapse.

Should auditors suggest corrective actions?

Generally no; auditors identify the gap and the auditee determines the action.

What is an observation?

A potential issue or improvement opportunity that is not a nonconformity.
