ISO 9000
ISO 9000 is a family of standards for quality management systems. ISO 9000 is maintained by ISO, the International Organization for Standardization and is administered by accreditation and certification bodies. Some of the requirements in ISO 9001 (which is one of the standards in the ISO 9000 family) includea set of procedures that cover all key processes in the business;
monitoring processes to ensure they are effective;
keeping adequate records;
checking output for defects, with appropriate and corrective action where necessary;
regularly reviewing individual processes and the quality system itself for effectiveness; and
facilitating continual improvement A company or organization that has been independently audited and certified to be in conformance with ISO 9001 may publicly state that it is "ISO 9001 certified" or "ISO 9001 registered." Certification to an ISO 9000 standard does not guarantee the compliance (and therefore the quality) of end products and services; rather, it certifies that consistent business processes are being applied.
Although the standards originated in manufacturing, they are now employed across a wide range of other types of organizations. A "product", in ISO vocabulary, can mean a physical object, or services, or software. In fact, according to ISO in 2004, "service sectors now account by far for the highest number of ISO 9001:2000 certificates - about 31% of the total." [1]
ISO 9001 certification does not guarantee that the company delivers products of superior (or even decent) quality. It just certifies that the company engages internally in paperwork prescribed by the standard. Indeed, some companies enter the ISO 9001 certification as a marketing tool
ISO 9000 family
ISO 9000 includes the following standards:ISO 9000:2000, Quality management systems – Fundamentals and vocabulary. Covers the basics of what quality management systems are and also contains the core language of the ISO 9000 series of standards. A guidance document, not used for certification purposes.
ISO 9001:2000 Quality management systems – Requirements is intended for use in any organization which designs, develops, manufactures, installs and/or services any product or provides any form of service. It provides a number of requirements which an organization needs to fulfill if it is to achieve customer satisfaction through consistent products and services which meet customer expectations. It includes a requirement for the continual (i.e. planned) improvement of the Quality Management System, for which ISO 9004:2000 provides many hints. This is the only implementation for which third-party auditors may grant certification. It should be noted that certification is not described as any of the 'needs' of an organization as a driver for using ISO 9001 (see ISO 9001:2000 section 1 'Scope') but does recognise that it may be used for such a purpose (see ISO 9001:2000 section 0.1 'Introduction').ISO 9004:2000 Quality management systems - Guidelines for performance improvements. covers continual improvement. This gives you advice on what you could do to enhance a mature system. This standard very specifically states that it is not intended as a guide to implementation. There are many more standards in the ISO 9001 family (see "List of ISO 9000 standards" from ISO), many of them not even carrying "ISO 900x" numbers. For example, some standards in the 10,000 range are considered part of the 9000 family: ISO 10007:1995 discusses Configuration management, which for most organizations is just one element of a complete management system. ISO notes: "The emphasis on certification tends to overshadow the fact that there is an entire family of ISO 9000 standards ... Organizations stand to obtain the greatest value when the standards in the new core series are used in an integrated manner, both with each other and with the other standards making up the ISO 9000 family as a whole".
Note that the previous members of the ISO 9000 family, 9001, 9002 and 9003, have all been integrated into 9001. In most cases, an organization claiming to be "ISO 9000 registered" is referring to ISO 9001.
