Document Review In ISO 9000 Standards

The ISO 9000 Standard requires that documents be reviewed.

Previously the implication was that the review was a

check by potential users that the document was fit

for purpose before it was offered for approval. It

could be construed that for a document to receive

approval it must be checked and therefore ‘review

and approval’ in this context are one and the same

and the requirement is in this instance enhanced

rather than relaxed.

A review is another look at something. Therefore

document review is a task that is carried out at any

time following the issue of a document.

This requirement responds to the Continual Improvement principle.

Reviews may be necessary when:

- Taking remedial action (i.e. Correcting an error)

- Taking corrective action (i.e. Preventing an error recurring)

- Taking preventive action (i.e. Preventing the occurrence of an error)

- Taking maintenance action (i.e. Keeping information current)

- Validating a document for use (i.e. When selecting documents for use in

connection with a project, product, contract or other application)

- Taking improvement action (i.e. Making beneficial change to the

information)

Reviews may be random or periodic. Random reviews are reactive and arise

from an error or a change that is either planned or unplanned. Periodic reviews

are proactive and could be scheduled once each year to review the policies,

processes, products, procedures, specification etc. for continued suitability. In

this way obsolete documents are culled from the system. However, if the

system is being properly maintained there should be no outdated information

available in the user domain. Whenever a new process or a modified process

in installed the redundant elements including documentation and equipment

should be disposed of.

Managing processes In ISO 9001 Standard

The standard requires the organization to manage the identified processes in accordance with the requirements of ISO 9001. The first stage in managing a process is to establish what it is you are trying to achieve, what requirements you need to satisfy, what goals you are aiming at; then establish how you will measure your achievements. The next stage is to define the process you will employ to deliver the results. Managing the process then involves managing all the inherentcharacteristics of the process in such a manner that the requirements of customers and interested parties are fulfilled by the process outcomes. This means:Managing the process inputsManaging the workManaging the physical resourcesManaging the financial resourcesManaging the human resourcesManaging the constraintsManaging the outputs
Process management is therefore much more than managing activities and therefore when describing processes, one needs more than a flow chart of activities. The chart is a diagrammatical representation of a process but only one aspect. One can also add numerical data to the charts to indicate resources, cycle times, delays, costs etc. but the intangible factors of the human environment cannot be reduced to numerical data to add to the charts.
The notes to clause 4.1 of ISO 9001 need some explanation. It is stated that the processes needed for the management system include management activities, provision of resources, product realization and measurement. This note could cause confusion because it suggests that these are the processes that are needed for the management system. It would be unwise to use this as the model and far better to identify the processes from observing how the business operates. The term provision of resources should be Resource Management, which is thecollection of processes covering financial, human and physical resources.
Product realization is also a collection of processes such as design, production, service delivery, etc. Measurement is not a single process but a sub-process within each process. Grouping all the measurement processes together serves no useful purpose except it matches the standard – a purpose of little value in managing the organization.
The second note refers to outsourcing processes although it is difficult to imagine that management activities, product realization or measurement would be outsourced in its entirety. It is likely that market research; design, product verification, equipment calibration and other specialized services may be outsourced. While outsourcing comes under purchasing, it is correct to point out that the organization should control any outsourced processes. The supplier of the process is usually referred to as a subcontractor because they provide services to the organization’s requirements not their own. Control of subcontractors is covered by clause 7.4 but in meeting clause 7.4.3, you need to treat suppliers and subcontractors differently.

ISO 9000 Series and Six Sigma

ISO (International Organization for Standardization) 9000 series standards were first published in 1987, revised in 1994, and re-revised in 2000 by the ISO. The 2000 revision, denoted by ISO 9000:2000, has attracted broad expectations in industry.
As of the year 2001, more than 300,000 organizations world-wide have been certified to the ISO 9000 series standards. It embodies a consistent pair of standards, ISO 9001:2000 and ISO 9004:2000, both of which have been significantly updated and modernized. The ISO 9001:2000 standard specifies requirements for a quality management system for which third-party certification is possible, whereas ISO 9004:2000 provides guide- lines for a comprehensive quality management system and performance improvement through Self-Assessment.
The origin and historical development of ISO 9000 and Six Sigma are very different. The genesis of ISO 9000 can be traced back to the standards that the British aviation industry and the U.S. Air Force developed in the 1920s to reduce the need for inspection by approving the conformance of suppliers’ product quality. These standards developed into requirements for suppliers’ quality assurance systems in a number of western countries in the 1970s. In 1987 they were amalgamated into the ISO 9000 series standards.
Independent of ISO 9000, the same year also saw the launch of Six Sigma at Motorola and the launch of Self-Assessment by means of the Malcolm Baldrige National Quality Award in USA. Both Six Sigma and Self-Assessment can be traced back to Walter A. Shewhart and his work on variation and continuous improvement in the 1920s. It was Japanese industry that pioneered a broad application of these ideas from the 1950s through to the 1970s. When variation and continuous improvement caught the attention of some of the American business leaders in the late 1980s, it took the form of the Malcolm Baldrige National Quality Award, on a national level, and of Six Sigma at Motorola.
Some people are wondering if the ISO 9000:2000 series standards make Six Sigma superfluous. They typically refer to clause 8 of ISO 9001: “Measurement, analysis, improvement.”
It requires that companies install procedures in operations for the measurement of processes and data analysis using statistical techniques with the demonstration of continuous improvement . They also partly refer to the ISO 9004:2000 standards that embody guidelines and criteria for Self-Assessment similar to the national quality awards.
The author firmly believes that Six Sigma is needed regardless of whether a company is compliant with the ISO 9000 series. The two initiatives are not mutually exclusive and the objectives in applying them are different. A Six Sigma program is applied in organizations based on its top-line and bottom-line rationales. The primary objective for applying the ISO 9000 series standards is to demonstrate the company’s capability to consistently provide conforming products and/or services. Therefore, the ISO 9000 series standard falls well short of making Six Sigma superfluous.
The ISO 9000 series standards have from their early days been regarded and practiced by industry as a minimum set of requirements for doing business. The new ISO 9000:2000 stan
dards do not represent a significant change to this perspective. Six Sigma on the other hand, aims at world-class performance, based on a pragmatic framework for continuous improvement.
The author believes that Six Sigma is superior in such important areas as rate of improvement, bottom-line and top-line results, customer satisfaction, and top-level management commitment. However, considering the stronghold of ISO 9000 in industry, Six Sigma and ISO 9000 are likely to be applied by the same organization, but for very different purposes.
