ISO 9001:2000 Quality Management System Requirements
General
General: The design and implementation of an organization’s quality management system is influenced by varying needs, particular objectives, the products provided, the processes employed, and the size and structure of the organization.
This International Standard can be used by internal and external parties, including certification bodies, to assess the organization’s ability to meet customer requirements.
Process-Based Approach
Process-Based Approach: This international standard promotes the adoption of a process approach for developing, implementing, and improving the effectiveness of a quality management system.
One advantage of the process approach is the continuous monitoring of the binding sites between individual processes within the system of processes and their combination and interaction. When used in a quality management system, this approach emphasizes the importance of:
- Understanding and meeting requirements
- Considering processes in terms of value-added
- Obtaining results of process performance and effectiveness
- Continually improving processes based on objective measures
NOTE: Additionally, you can apply the “Plan-Do-Check-Act” (PDCA) methodology to all processes. PDCA can be briefly described as:
- Plan: Establish the objectives and processes necessary to deliver results following customer requirements and organizational policies.
- Do: Implement the processes.
- Check: Monitor and measure processes and products against policies, objectives, and product requirements, and report results.
- Act: Take action to improve process performance continually.
Relation with ISO 9004
Relation with the International Standard ISO 9004:
ISO 9001 specifies requirements for a quality management system that organizations could use for internal application, certification, or contractual purposes. It focuses on the effectiveness of quality management in complying with the quality management system requirements.
ISO 9004 provides guidance on a wider range of objectives of a quality management system than ISO 9001, especially for continuous performance improvement and overall organizational effectiveness. ISO 9004 is recommended as a guide for organizations whose top management needs to go beyond ISO 9001’s requirements, pursuing continuous performance improvement. However, it is not intended for certification or contractual purposes.
Compatibility with Other Management Systems
Compatibility with other management systems:
ISO 14001:1996, to improve the compatibility of the two standards for the benefit of the user community.
This International Standard does not include requirements specific to other management systems, such as those particular to environmental management, occupational health and safety management, financial management, or risk management. However, this International Standard enables an organization to align or integrate its quality management system with related management system requirements. It is possible for an organization to adapt its existing management system(s) to establish a quality management system that meets this International Standard’s requirements.
Purpose and Scope
1.1 General
1.1 General: This International Standard specifies requirements for a quality management system applicable when an organization:
- Needs to demonstrate its ability to provide products that consistently meet customer and applicable regulatory requirements.
- Intends to achieve customer satisfaction through the effective implementation of the system, including processes for continual improvement and ensuring compliance with customer and applicable regulatory requirements.
NOTE: In this International Standard, the term “product” applies only to the product intended or requested by the customer.
1.2 Application
1.2 AplicaciĆ³n: All requirements of this International Standard are generic and intended to be applicable to all organizations, regardless of type, size, or product provided. Where any requirement of this International Standard cannot be applied due to the organization’s nature and its product, its exclusion can be considered.

2 Normative references:
The International Standard quoted below contains provisions that, by reference in this text, constitute provisions of this International Standard. As the referenced standard is dated, subsequent amendments or revisions of the above International Standard do not apply. However, it is recommended that parties to agreements based on this International Standard consider applying the most recent edition of the International Standard listed below. Members of IEC and ISO maintain registers of International Standards in force at the time.
- ISO 9000:2000, Quality Management Systems – Fundamentals and Vocabulary
3 Terms and Definitions
3 Terms and definitions:
For this International Standard, the terms and definitions given in ISO 9000:2000 apply.
The following terms used in this edition of ISO 9001 to describe the supply chain have been changed to reflect the vocabulary currently in use:
———————— Organization ———————— Customer
The term “organization” replaces the term “supplier organization” used in ISO 9001:1994 and refers to the unit applying this International Standard. Similarly, the term “supplier” is currently used instead of “subcontractor.”
Throughout this International Standard, wherever the term “product” appears, it can also mean “service.”
