Quality & standardsISO 9001 Quality Management

What is ISO 9001?

ISO 9001 is the world’s most widespread management standard: it sets requirements for a quality management system that ensures the organisation consistently delivers products and services meeting customer and regulatory requirements, and improves continuously.

The standard is built on process orientation, risk-based thinking and PDCA. Certification is done through accredited certification bodies with annual audits. ISO 9001:2026 was published on 16 September 2026 and supersedes ISO 9001:2015 (with Amendment 1:2024 on climate considerations), which remains valid for the length of the transition. The transition must be complete by 30 September 2029, and from 31 March 2028 no new accredited certificates can be issued against the 2015 edition.

The pitfall is building the system for the auditor instead of for operations: a quality system that only lives in documents passes audits but prevents no defects.

CAPA

CAPA (Corrective and Preventive Action) is the quality system’s process for handling deviations: corrective actions remove the root cause of an error that has occurred, so it doesn’t recur; preventive actions remove the risk before the error occurs.

SOP

An SOP (Standard Operating Procedure) is a documented work instruction that describes how a task is performed correctly: steps, responsibility, equipment and critical control points. SOPs are the backbone of quality management and a basic requirement in ISO 9001 contexts.

Audit

An audit is a systematic, independent examination of whether a management system meets the requirements, and whether it is complied with in practice. Internal audits are performed by the organisation itself; external audits by customers (2nd party) or certification bodies (3rd party).

PDCA

PDCA (Plan-Do-Check-Act) is the fundamental improvement cycle: plan a change with a hypothesis, carry it out on a small scale, check the result against the expectation, and act — standardise if it worked, adjust if not. The cycle repeats.

From concept to practice

The methods only work when they are anchored in daily routines and leadership behaviour. The operations check shows in 4 minutes where your operations stand, and what the next step is.
