ISO 9001
An international standard for a quality management system, against which a business can be audited and certified.
What it means in business
ISO 9001 sets out requirements for how a business manages quality: knowing what customers need, controlling its processes, keeping records, and improving. A certification body audits the business against it and can certify it. It is about the system, not about approving individual products.
Example
A component supplier gets ISO 9001 certified because large customers ask for it. It documents its processes, trains staff and holds internal audits, and the certification body audits it each year. This is an illustration of normal business use rather than a quoted case study.
How to use it correctly
Decide why you want it, whether customer demand or better control, and choose an accredited certification body. Build the system around how work is really done so the documents are used.
Common confusion
ISO 9001 certification does not mean the products meet a technical standard: product approvals such as BIS marking are separate. It is also not a one-time award, since it is reviewed through regular audits.
