ENV729 Nonconformity and Corrective Action
Nonconformities

As discussed, during the Check step of the PDCA, the organization should be able to identify nonconformities (NCs) of the EMS. NCs can be:
- real and known or potential and suspected only;
- major or minor;
- urgent or requesting a long term approach;
- symptomatic or asymptomatic;
- operational or documentary
They can be related to any document, aspect, activity, process within the EMS.
Searching the cause for a Nonconformity
The 5 Whys Analysis can help to find root causes for NCs. Watch this video (1:30) with a concrete illustration of what it is:
However, here is an interesting critic of the 5 Whys Analysis. 5 Whys may not solve all NCs…
Corrective actions

Once the cause is known, the organization must respond appropriately and correct the NC. The response must be:
- Aiming to control and fix the NC and face the consequences by mitigating the negative impacts
- Reviewing the NC and determining whether actions can eliminate the root cause of the NC
- Implementing actions via a plan
- Reviewing the effectiveness of any corrective action plan
- Modifying the EMS, if necessary
The NC can be closed if it is corrected.
Additionally, a preventing action plan can be implemented to avoid the NC from occurring again. otherwise, a follow-up of the preventive action plan will be necessary.
Monitoring action plans

Through follow-ups, the organization will:
- Evaluate the performance of the action plans;
- Close the NCs; or
- Consider modifying and improving the action plan;
- Document the follow-up (name of the person in charge, date, observations, evidence, findings, etc.).
All these corrective actions improve the performance of the EMS through a continual process.
To Do list

- List all the NCs
- Find their root cause(s)
- Address the root cause(s) via a corrective action plan
- Monitor the performance of the corrective action plan
- Close NCs and improve the corrective action plan
- Consider preventive action plans
