Audit findings: How to write nonconformities

Audit findings- how to write nonconformities_blog post feature image

This article covers some useful examples of how to write clear, objective nonconformities during an internal audit or supplier audit.  

Auditing expert Peter Sebelius walks through real-world audit scenarios, demonstrating how to reference requirements correctly and avoid common pitfalls—such as making assumptions or drawing subjective conclusions.  

The video above is a sneak peak of Peter’s online course on ISO 13485 Internal Auditing, where you can find even more practical tips and hands-on training for conducting effective audits. 

What is a nonconformity?

It is very important that audits are objective, which means that the audit evidence must be evaluated objectively against the audit criteria to determine if the auditee conforms to the requirements (conformity) or does not conform (nonconformity). 

So, simply put. A conformity is the fulfilment of a requirement, whereas nonconformity, means nonfulfillment of a requirement.  

The difference between conformity and compliance

If the audit criteria for the audit are selected from statutory and regulatory requirements, the audit findings should be referred to as compliance or non-compliance.  

When referring to standards, the auditee is either conforming or nonconforming. However, the Medical Device Regulation and the In-Vitro Diagnostic Medical Device Regulation are examples of statutory regulatory requirements, and in these cases, the terms compliance or non-compliance should be used. 

What to keep in mind when collecting audit evidence and compiling audit findings

The auditor should always maintain objectivity and refrain from jumping to conclusions. If there is no objective evidence that the auditee is not conforming to the audit criteria, a nonconformity should not be written.

Internal auditor

The auditor’s job is to collect sufficient audit evidence to be able to determine if the auditee is conforming or not. The auditor should not have any personal opinions on how the auditee runs its organisation, nor should he or she guess or assume anything. 

One sure way of ensuring that the auditor does not become subjective is to follow the method for writing nonconformities that is described in the examples below.

Nonconformity examples: Writing nonconformities to 5.2 in ISO 13485

The 5.2 requirement states:

Top management shall ensure that customer requirements and applicable regulatory requirements are determined and met.

The auditing scenario

During the audit, let’s say that the auditor learns that the auditee is developing a software that will process personal data for EU customers. The management representative confirms that they have not considered the General Data Protection Regulation, or short GDPR, that apply in this case. This means that the applicable regulatory requirements have not been determined

How to write the nonconformity

When writing the nonconformity, use the following steps:  

  1. use the requirement text,
  2. remove any unnecessary text, including the section number, and
  3. negate the sentence.  

Applying these steps to the situation above will result in the following nonconformity: 

5.2 Top management has not shall ensured that customer requirements and applicable regulatory requirements are determined and met.

The only information that the auditor has at this time is that the auditee has not considered the GDPR. So, anything else in the requirement should be removed.  

What about ensuring GDPR requirements have been met? Could, or even should the nonconformity include this requirement too? At this time, there is no evidence to show that the auditee did not meet GDPR requirements. It is, of course, unlikely, but the auditee might, for example, have implemented more rigorous data protection procedures that would meet or exceed GDPR requirements without having determined that GDPR apply.  

Thus, the only thing that should be kept in the description of the nonconformity is that the auditee has not ensured that the applicable regulatory requirements have been determined.  

This goes back to not jumping to conclusions. The final description of the nonconformity is:  

Top management has not ensured that applicable requlatory requirements are determined.

No more, no less than that.

Nonconformity examples: Writing nonconformities to 5.3 in ISO 13485

Section 5.3 is also about management responsibility and includes items a) through e) but this example will focus on d), which reads:

Top management shall ensure that the quality policy:… d) is communicated and understood within the organization;

The auditing scenario

During the audit, the auditor asks a few people in the organisation what the quality policy means to them, and they say that they don’t understand it.  

When the quality policy is shown to them, staff member C say that it is only applicable to the quality department. So, the auditor can conclude that the quality policy is not understood within the organisation.

How to write the nonconformity

Again, the section number will be removed and the sentence negated by replacing shall with has not. At this time, the auditor does not know if management has communicated the quality policy or not so “communicated and” should be removed. This results in the following nonconformity:  

Top management has not ensured that the quality policy is understood within the organization.

The important thing is to not expand the nonconformity to comprise more aspects than there is evidence for. Remember, just because the staff doesn’t understand, it doesn’t mean it wasn’t communicated.

Nonconformity examples: Writing nonconformities to 4.2.5 in ISO 13485

Next example is from section 4.2.5 and relates to records. The requirement reads:

4.2.5 … Records shall remain legible, readily identifiable and retrievable.

The auditing scenario

During the audit, the auditor notices that the thermally printed cleaning record from dishwasher EQ002 from the 4th of May 2019 has faded and that the last three rows cannot be read.

How to write the nonconformity

As always, start with the requirement, remove the section number and any irrelevant words, and add “have not”. This results in the nonconformity:

Records have not remained legible.

Writing conformities

If the auditor is required to document conformities as well, the same approach can be applied, usually with the addition of some evidence. If we assume that the situation above with the faded cleaning record had been copied to a paper where the text remained legible, the conformity could read: 

When examining the cleaning record for the EQ002 dishwasher from 4th of May 2019, records were found to remain legible, identifiable, and retrievable

Basically, the conformity is made up of the conformity description together with audit evidence.

Final words on writing nonconformities

Sticking to this way of writing nonconformities is key to getting it right. When a different approach to writing nonconformities is applied, it is likely that the nonconformity can be seen as subjective.
