ISO 9001
The international standard for quality management systems, requiring documented procedures, continuous improvement, and risk-based thinking.
Definition
ISO 9001:2015 is the world's most widely used quality management system (QMS) standard, published by the International Organization for Standardization. It defines requirements for documented procedures, competent personnel, measured performance, and continuous improvement. Over 1 million organizations across 170+ countries are ISO 9001 certified. The standard mandates that an organization maintain 'documented information' (SOPs, work instructions, forms, records) for processes that affect product or service quality.
Why it matters
ISO 9001 certification is often a prerequisite for supplying major customers, government contracts, and regulated industries. It's also a defensible audit framework — if your SOPs are aligned with ISO 9001 clauses, you're automatically meeting requirements for many customer quality audits. The 2015 revision moved the standard toward risk-based thinking and away from prescriptive documentation, but documented procedures remain a cornerstone.
