ISO 9001 is an international standard published by the International Organization for Standardization (ISO) that defines requirements for a Quality Management System (QMS). It provides a framework to help organizations consistently deliver products and services that meet customer and applicable legal and regulatory requirements and to enhance customer satisfaction. With over one million certifications issued in 189 countries worldwide it is the most widely used quality management standard. ISO 9001 demonstrates that an organization has established effective processes and trained personnel to deliver flawless products or services on time.
The standard is designed with a general structure that can be applied to any organization regardless of sector type or size. It is suitable for all industries including manufacturing services healthcare education public sector and nonprofit organizations. The current version of the standard is ISO 9001:2015 which was most recently reviewed and confirmed in 2021. It is indicated that a new revision is under development and expected to be published in 2026.
ISO 9000 Family of Standards
ISO 9001 is part of the ISO 9000 family of standards which address various aspects of quality management and include some of ISOs most well-known standards. One of the key standards in this family ISO 9000 defines the fundamental concepts and terminology of quality management. ISO 9001 is the only standard within this family that can be certified although certification is not mandatory. Another standard in the family ISO 9004 provides guidance on how to make an implemented Quality Management System more successful by focusing on improving existing processes and offering best practice insights.
Quality Management Principles
The ISO 9001 standard and all other quality management standards in the ISO 9000 family are based on seven fundamental quality management principles. These principles provide a foundation to help organizations improve their performance and achieve sustainable success. The principles are as follows:
- Customer Focus: The primary focus of organizations should be on meeting customer requirements and striving to exceed expectations. Increasing customer satisfaction is seen as the key to long term success.
- Leadership: Top management must establish unity of purpose and direction to enable the organization to achieve its quality objectives and create the necessary environment to reach them. Leadership commitment is critical to the effectiveness of the QMS.
- Engagement of People: Competent empowered and involved people at all levels increase the organization’s capacity to create value. Involving employees in processes enhances motivation and productivity.
- Process Approach: When activities are understood and managed as interrelated processes consistent and predictable results are achieved more effectively and efficiently.
- Improvement: Successful organizations focus on continual improvement. This principle enables organizations to adapt to changing internal and external conditions and create new opportunities.
- Evidence Based Decision Making: Decisions based on the analysis and evaluation of data and information are more likely to produce desired results.
- Relationship Management: Organizations manage relationships with interested parties such as suppliers and partners to achieve sustainable success. Strong supplier relationships enhance quality and efficiency.
Structure and Requirements of the Standard
ISO 9001:2015 follows the High Level Structure (HLS) known as Annex SL to facilitate compatibility with other ISO management system standards. This common structure makes the integration of different standards such as ISO 14001 (Environmental Management System) and ISO 45001 (Occupational Health and Safety Management System) more effective and efficient. The standard consists of ten main clauses. The first three clauses are introductory while the last seven contain the requirements for a QMS.
The clauses containing the core requirements are as follows:
- Clause 4: Context of the Organization: This section addresses the need for the organization to understand itself in order to implement the QMS. It includes identifying internal and external factors relevant interested parties and their expectations defining the scope of the QMS and determining processes and their interactions.
- Clause 5: Leadership: Leadership requirements emphasize that top management must play an active role in implementing the QMS. Top management is expected to demonstrate commitment to the QMS establish a quality policy and define organizational roles responsibilities and authorities.
- Clause 6: Planning: This clause covers actions designed to help the organization achieve its quality objectives and continually improve the effectiveness of the system. It includes addressing risks and opportunities and setting quality objectives.
- Clause 7: Support: This addresses supporting elements necessary for the operation and maintenance of the QMS such as resources competence awareness communication and documented information.
- Clause 8: Operation: This covers the planning implementation and control of processes necessary to meet customer requirements and enhance customer satisfaction. It includes the design development production and delivery of products and services.
- Clause 9: Performance Evaluation: This specifies the need for the organization to monitor measure analyze and evaluate the performance and effectiveness of the QMS. Internal audits and management review are key elements of this clause.
- Clause 10: Improvement: This emphasizes the importance of continually enhancing the effectiveness of the QMS based on the results of performance evaluation and other data sources. It addresses the management of nonconformities and corrective actions.
A risk based thinking approach has been integrated throughout the standard. This approach ensures that risk is systematically addressed within a quality management system and helps organizations identify potential issues in advance to allocate resources to areas of greatest need.

The certification process typically includes the following steps:
