Quality control and ISO 9001 in production
How the quality system connects to your daily work
Quality is not something that only happens in a laboratory or with a quality department — it happens on the floor, every time you check a measurement, notice a deviation or follow a work instruction. Many manufacturing companies control their quality work according to a quality management system, and the most widespread in the world is the international standard ISO 9001, which is administered in Denmark by Danish Standard.
§What is a quality management system?
A quality management system is the company's overall way of planning performing controlling and improving its work so products and services meet customer requirements and legislation. It is not just paperwork — it is the work processes checklists control points and deviation reports you encounter in your daily work as a production worker.
§ISO 9001 – the international standard
ISO 9001 is an international standard for quality management that sets requirements for how a company establishes, implements, maintains and continuously improves its quality management system. The standard is based on a number of quality management principles, and companies can be certified by an independent certification body if they meet the requirements.
- 01Strong customer focus — the product must meet the customer's and the law's requirements
- 02Management commitment — management must take the lead and allocate resources
- 03Process-oriented approach — work is seen as interconnected processes, not isolated tasks
- 04Løbende forbedring — fejl og afvigelser bruges til at blive bedre, ikke kun til at bebrejde
- 05Fact-based decision-making — decisions are made based on data and measurements, not gut feeling.
§How you mark it as a producer
In your daily life, the quality system shows itself as concrete tools: work instructions that describe how a task should be carried out; control forms where you record measurements and results; and a fixed procedure for what should happen when you discover a deviation. Traceability is central — it must always be possible to see who did what, with which materials and under which checks, if a question about a product later arises.
| Step | What's happening |
|---|---|
| 1. Discover | You see or measure something that deviates from the requirement. |
| 2. Record | The deviation is noted with what, where and how much |
| 3. Insulate | The affected products are marked or set aside so they are not sent on |
| 4. Examine | The cause is found — was it the machine, material, or method? |
| 5. Correct | Action is taken: adjustment rework rejection or information to the customer |
| 6. Prevent | A change is made so the deviation does not repeat |
§Certification and audit
A company that is ISO 9001-certified is continuously audited — both by internal auditors and by the external certification body. An audit is a systematic review of whether the company actually does as it says in its procedures. As a producer you may experience being asked by an auditor how you perform a task or where you find an instruction — it is a completely normal part of working in a certified system.
§Why it matters for you
A good quality system does not make work bureaucratic for the sake of bureaucracy — it makes clear what is expected and it catches faults before they become expensive or dangerous. When you follow the instructions and report deviations you are an active part of the system that keeps the company's quality up.
“Quality is not a control at the end of the line — it is something that is built into every single step along the way.”
