Clause 10 is where intention meets accountability. It requires your organization to determine and select opportunities for improvement and implement necessary actions to meet customer requirements and enhance customer satisfaction. This sounds aspirational, but the standard backs it up with specific requirements: you must handle nonconforming output, conduct corrective actions when problems occur, and systematically pursue continual improvement. A shop can have beautiful documentation and good intentions but fail at Clause 10 if it does not close the loop on problems. A nonconformance is discovered but nothing changes; it happens again a few months later. A corrective action is launched but never verified to ensure it actually fixed the problem. An opportunity for improvement is identified but sits on a list without priority or resource allocation. This pattern is common and is why auditors pay close attention to Clause 10. They want to see evidence that when a problem is found, it is addressed and prevented from recurring.
Handling nonconforming output, covered briefly under Clause 8, receives detailed attention here. When a part or service is found to not meet requirements, your procedure should specify how to evaluate it: Can it be used as-is (conformance after all)? Can it be reworked to conformance? Should it be scrapped? Does it require customer notification or approval? The decision should be documented along with the justification and who approved it. If a part is scrapped, the root cause should be investigated. Why did a conformance failure happen? Was it a one-time operator error, or does it indicate a systemic problem? A single error might not warrant investigation; repeated errors in the same operation warrant an investigation and likely a corrective action. When you use the QMS2GO manufacturing guide, you can structure your nonconformance handling and corrective action process so it is consistent, documented, and actually closed rather than left in limbo.
Corrective Action: Getting to Root Cause
The most misunderstood aspect of corrective action is that finding a root cause requires structured thinking. Many shops treat root-cause analysis superficially: "The part failed because the operator made a mistake" stops the investigation at the symptom and misses the actual root cause. Why did the operator make a mistake? Was the procedure unclear? Was the operator inadequately trained? Was the tool worn and producing off-tolerance parts? Was the procedure itself inadequate for the current customer requirements? These are the deeper questions that identify actual root causes. A common methodology is the Five Why technique: when you have identified one cause, ask "why" to dig one level deeper, and repeat until you reach a cause where an action can prevent recurrence. Another methodology is 8D (8 Dimensions), which is more rigorous and is often required in automotive and aerospace contexts. The methodologies matter less than the discipline: structured root-cause analysis beats guessing. Corrective actions should be targeted at the root cause, not the symptom. If the root cause is inadequate training, the corrective action is to retrain; it is not to replace the operator. If the root cause is inadequate procedure, the corrective action is to revise the procedure and retrain people to the new version.
Verification: Did It Actually Work?
A corrective action is not complete until you verify that it actually fixed the problem. This means that after implementing the corrective action, you should track the relevant metric or process to confirm that the problem does not recur. If the corrective action was to revise a machining procedure to tighter tool-change intervals, you should track scrap rate in that operation for weeks or months to confirm that the new intervals are preventing the previous failures. If the corrective action was to retrain an operator, you should observe that operator and review inspection results from parts they produce to confirm they are now performing at standard. Verification should be documented in your corrective action record. Many shops launch corrective actions but never verify them, so they repeat in six months without realizing the original corrective action failed. The best corrective actions are also institutionalized—after verification, the change becomes permanent. The new procedure becomes the standard; the new training becomes part of onboarding for all new employees in that role; the new tool-change interval becomes the routine practice rather than an exception.
Continual Improvement as Strategic Discipline
Beyond reactive corrective action, Clause 10 requires your organization to pursue continual improvement. This means systematically identifying opportunities to enhance processes, reduce costs, improve safety, increase customer satisfaction, or accelerate delivery. Some improvement opportunities come from data analysis under Clause 9: you notice that a particular operation accounts for most of your scrap, so you prioritize improving that operation. Some come from employee ideas: a machinist proposes a fixture design that would reduce setup time. Some come from customer feedback: a customer mentions that they wish you could deliver faster or offer a lower minimum. Some come from external benchmarking: you learn that competitors are achieving better scrap rates and study how. Continuous improvement is not a one-time project; it is a cultural practice where everyone is encouraged to spot problems and suggest solutions.
Many of the best improvements come not from the quality department but from production floor employees who know the work intimately. A shop that creates a simple channel for ideas—a suggestion box, a standing agenda item in production meetings, or a recognition program for implemented ideas—often finds that employees generate more improvement ideas than management can resource. The discipline is then deciding which ideas to prioritize and resource, implementing them, and verifying the results. Some organizations use a structured approach like Kaizen events (intensive workshops focused on a specific process over a few days) or lean methodologies that emphasize continuous incremental improvement. Others use a less formal approach but still require that ideas go through a simple evaluation and tracking process. What matters is that improvement is intentional and not accidental, that progress is measured, and that the organization learns from its efforts.
