Quality Assurance In ISO 9001 Standards

Quality assurance, according to the ISO 9001 Standard, is a way of managing that prevents non-conformance and thus “assures quality”. This is what makes ISO 9001 Standardsdifferent from other standards: it is a management standard, not a product standard. It goes beyond product standardisation: it is standardising not what is made but how it is made.

To use the ISO 9001 standards to dictate and control how organisations work was to extend the role of standards to new territory. To take such a step we might have firstly established that any such requirements worked — that they resulted in ways of working which improved performance. Yet the plausibility of this Standard, and the fact that those who had an interest in maintaining it were (and still are) leading opinion, prevented such enquiries. In simple terms the Standard asks managers to say what they do, do what they say and prove it to a third party. ISO 9000 (2008) paragraph 1: “The requirements specified are aimed primarily at achieving customer satisfaction by preventing non-conformity at all stages from design through servicing.” To put it another way, the Standard asserts that preventing non-conformance achieves customer satisfaction. But does it? Of course it matters to customers that a product works. But there is no guarantee that the Standard will ensure even that.

Furthermore, customers take a total view of an organisation — how easy it is to do business with — in respect of all things of importance to each and every customer. ISO 9000 requires managers to “establish and maintain a documented quality system as a means of ensuring that product conforms to specified requirements”. Loosely translated this is “say what you do”. Management is supposed to “define and document its policy for quality . . . including its commitment to quality”. What management would not declare its commitment to quality? But would they know what it means? Would they argue (as they should) that quality management is a different and better way to do business, or would they believe that ISO 9001 Standardswill take care of quality?

The ISO 9000 Standards encourages managers to think of “quality” and “business as usual” as separate and distinct. It helps managers avoid the revelation that quality means a wholly different view of management. Instead, the organisation “shall appoint a management representative who, irrespective of other responsibilities, shall have defined authority and responsibility” [for ISO 9000]. At a practical level this means only one executive might decide he or she had better learn a thing or two about quality.

However, would being responsible for ISO 9001 standards lead to learning about quality or simply enforcing the ISO 9000 regime in an organisation? Key to the regime is auditing. The Standard requires organisations to conduct internal quality audits to “verify whether quality activities comply with planned arrangements”. This can be loosely translated as “do you do as you say?” and the purpose of the audit is to see that you do. It was not until the 1994 review that the words were changed to “quality activities and related results”. It was a Standard which was rooted in the philosophy of inspection: fifteen years after its initial promulgation the promoters sought to extend the focus to results. But results or improvements assessed by what means? Inspection. By the time the Standard was adopted world-wide, quality thinking had moved a long way from the philosophy of inspection. It is now understood, at least by a few, that quality is achieved through managing the organisation as a system and using measures which enable managers to improve flow and reduce variation (which we explore in chapters 5 and 7).

The defenders argue that there is nothing stopping a company having ISO 9000 and implementing methods for managing flow and reducing variation, but where are such companies? Few of the companies we researched, formally and informally, knew anything about this thinking. The Standard does not talk about it; moreover, the Standard effectively discourages managers from learning about it by representing quality in a different way. According to ISO 8402 (quality vocabulary), quality is: “The totality of features and characteristics of a product or service that bear on its ability to satisfy stated or implied needs.” Everything we have learned about ISO 9000 suggests that the people who created this definition were thinking about the things which need to be controlled, those things which “bear on its ability . . .”. The builders of the Standard assumed that customer needs would be listed in contractual agreements between the supplier and customer. ISO 9000 has a “make” logic — procedures for “how you do what you do” — and a “control” logic — check to see that it is done. It is a relic of the era when contractual agreements were perceived to be an important device for regulating the behaviour of suppliers.

In these ways, ISO 9000 standards encouraged “planning for quality”. Planning for quality sounds plausible, but it assumes many things: that the plan is the right plan, that it is feasible, that people will “do it”, that performance will improve. It is an approach which, paradoxically, leads to poor decisions. Planners of quality systems, guided by ISO 9000 standards , start with a view of how the world should be as framed by the Standard. Understanding how an organisation is working, rather than how someone thinks it should, is a far better place from which to start change of any kind.

ISO 9001 Standard For Quality

The International Organization for Standardization, ISO, is a non-governmental agency that publishes and develops standards for the public and private sectors. From mechanical engineering and technology to agriculture, the ISO 9000 Standards establishes benchmarks and guidelines for quality products and services. ISO 9001 quality standards are a highly regarded and internationally recognized set of standards that are used in businesses, nonprofit groups and government organizations.

Since 1947, the ISO has published more than 17,500 standards. Many of these standards are specific for a product or process. In 1979, the ISO established the quality management and quality assurance committee. This committee established international quality management guidelines. The first guidelines published in 1986 were referred to as ISO 8402. These standards were updated and replaced with the ISO 9000 family of quality management systems standards. The latest round of quality standards fall under the ISO 9001:2008 title.

ISO quality standards include technical requirements, customer service levels, continual improvement requirements and documentation of key systems and processes. Quality is assured through strict process monitoring, checking for defects and routine internal and external reviews. Conformance with the rules and regulations of the ISO standards results in a company being publicly labeled as ISO 9001 certified or ISO 9001 registered.

Companies and organizations that adopt ISO quality standards increase their visibility as a quality-focused company. The public recognition as an ISO 9001 certified company could lead to increased access to contracts, especially for the government and to higher prestige in an industry. For some businesses, ISO 9001 certification is seen as a competitive advantage, while in other industries compliance is a requirement for continued operation.

The ISO claims that implementation of ISO standards increases a company’s return on investment, increases market share and profits and improves operational results. Societal benefits are improved health and safety, corporate compliance with legal requirements and reduced environmental impact.

The ISO quality standards and audits confirm compliance with the processes and business framework for a company to produce quality goods and services. Audits and reviews do not certify the actual products or services provided by a company, only the business methodology and quality systems that are designed to ensure quality. It is also a misconception that the ISO standards for quality only apply to manufacturing and physical goods. The ISO standardsare also applicable to the service industry.

Advantages Of ISO 9001 Standard

Successful firms are good at two things: increasing sales and reducing costs. However, these two things may prove irrelevant if the quality of the product or service is poor. ISO 9001 Standard is concerned with improving the quality of operations which can affect both top and and bottom line growth. Implementation of ISO 9001 Standard affects the entire organization by providing a transition to both a new common language and a new way of thinking about continuous process improvement. Here’s how you can bring the benefits of ISO 9001 Standard to your organization.

1. Obtain management buy-in. The most important step to any quality initiative is to obtain management commitment. This will increase both the visibility and awareness of your efforts.

2. Create an implementation team. This should include a representative from all functional areas of the organization including marketing, finance, planning, production and design. Also be sure to assign a Management Representative. This should be your strongest upper-level advocate for the success of ISO 9001 Standard implementation.

3. Communicate the goals of the program and provide training. This should include employees as well as major suppliers. The communication should be concise, tied to improving the success of current goals and objectives, and in a language in which employees are familiar with.

4. Map out the most critical processes of the current system. Use an organizational flow chart to show how information flows from the placement of an order to delivery. Compare this flowchart with the ISO 9001 system (see Resources for a link to Management Standards) and identify areas for improvement.

5. Create an implementation plan based on opportunities for improvement found in Step 4. The plan should be thorough and specific. Document each change in the process flowchart. If you already have documentation supporting your processes, use it. However, if you identify an area which lacks documentation, this should be viewed as an opportunity. Documentation is the lifeblood of continuous improvement. If you don’t already have one, create a documentation control system which manages the creation, approval, distribution, storage and disposal of documents.

6. Report out on improvements, create metrics to track improvements and repeat the process.ISO 9001 Standard is about continuous process improvements, and the success of the program is a function of both commitment and the achievement of this goal.

History and Evolution of ISO 9000 Standards

Pre ISO 9000
During World War II, there were quality problems in many British industries such as munitions, where bombs were exploding in factories during assembly. The solution adopted to address these quality problems required factories to document their manufacturing procedures and to prove by record-keeping that the procedures were being followed. The standard was BS 5750, and it was known as a management standard because it specified not what to manufacture, but how the manufacturing process was to be managed. In 1987, the British Government persuaded the International Organization for Standardization (ISO) to adopt BS 5750 as an international standard. The international standard was named ISO 9000.

ISO 9000: 1987 Version
ISO 9000:1987 had the same structure as the British Standard BS 5750, with three ‘models’ for quality management systems, the selection of which was based on the scope of activities of the organisation:
• ISO 9001:1987 Model for quality assurance in design, development, production, installation, and servicing was for companies and organisations whose activities included the creation of new products
• ISO 9002:1987 Model for quality assurance in production, installation, and servicing had basically the same material as ISO 9001 but without covering the creation of new products.
• ISO 9003:1987 Model for quality assurance in final inspection and test covered only the final inspection of finished product, with no concern for how the product was produced.
ISO 9000:1987 was also influenced by existing U.S. and other Defense Standards (MIL SPECS), and so was well-suited to manufacturing. The emphasis tended to be placed on conformance with procedures rather than the overall process of management—which was likely the actual intent.

ISO 9000:1994 (Year 1994 Revision)
ISO 9000:1994 emphasised quality assurance via preventive actions, instead of just checking final product, and continued to require evidence of compliance with documented procedures. As with the first edition, the down-side was that companies tended to implement its requirements by creating shelf-loads of procedure manuals, and becoming burdened with an ISO bureaucracy. In some companies, adapting and improving processes could actually be impeded by the quality system.

ISO 9000:2000 (Year 2000 Revision)
ISO 9001:2000 combines the three standards 9001, 9002, and 9003 into one, called 9001. Design and development procedures are required only if a company engages in the creation of new products. The 2000 version sought to make a radical change in thinking by placing the concept of process management front and centre (”Process management” was the monitoring and optimising of a company’s tasks and activities, instead of just inspecting the final product). The Year 2000 version also demands involvement by upper executives, in order to integrate quality into the business system and avoid delegation of quality functions to junior administrators. Another goal is to improve effectiveness via process performance metrics — numerical measurement of the effectiveness of tasks and activities. Expectations of continual process improvement and tracking customer satisfaction were made explicit.

ISO 9000:2008 (Year 2008 Revision)
The new ISO 9001:2008 was published on 15 November 2008. ISO 9001:2008 uses the same numbering system as ISO 9001:2000 to organise the standard. As a result, the new ISO 9001:2008 standard looks very much like the old standard. No new requirements have been added. However, some important clarifications and modifications have been made.

As with the release of previous versions, organisations registered to ISO 9001:2000 will be given a period to transition to the ISO 9001:2008 standard, assuming changes are needed.

ISO 9000 — a way of managing for conformance
Quality assurance, according to the Standard, is a way of managing that prevents non-conformance and thus “assures quality”. This is what makes ISO 9000 different from other standards: it is a management standard, not a product standard.

Quality characteristics in ISO 9000 Standards

Quality characteristics in ISO 9000 Standards

Any feature or characteristic of a product or service that is needed to satisfy customer needs or achieve fitness for use is a quality characteristic. When dealing with products the characteristics are almost always technical characteristics, whereas service quality characteristics have a human dimension. Some typical quality characteristics are given below.

Product characteristics

1. Accessibility Functionality Size

2. Availability Interchangeability Susceptibility

3. Appearance Maintainability Storability

4. Adaptability Odour – Strength

5. Cleanliness Operability -Taste

6. Consumption Portability – Testability

7. Durability Producibility Traceability

8. Disposability Reliability – Toxicity

9. Emittance Reparability Transportability

10. Flammability Safety – Vulnerability

11. Flexibility Security – Weight

Service quality characteristics

1. Accessibility Credibility – Honesty

2. Accuracy Dependability Promptness

3. Courtesy Efficiency - Responsiveness

4. Comfort Effectiveness Reliability

5. Competence Flexibility – Security

These are the characteristics that need to be specified and their achievement controlled, assured, improved, managed and demonstrated. These are the characteristics that form the subject matter of the product requirements referred to in ISO 9000. When the value of these characteristics is quantified or qualified they are termed product requirements. We used to use the term quality requirements but this caused a division in thinking that resulted in people regarding quality requirements as the domain of the quality personnel and technical requirements being the domain of the technical personnel. All requirements are quality requirements – they express needs or expectations that are intended to be fulfilled by a process output that possesses inherent characteristics. We can therefore drop the word quality. If a modifying word is needed in front of the word requirements it should be a word that signifies the subject of the requirements. Transportation system requirements would be requirements for a transportation system, Audio speaker design requirements would be requirements for the design of an audio speaker, component test requirements would be requirements for testing components, and management training requirements would be requirements for training managers. ISO 9000 requirements are often referred to as quality requirements as distinct from other types of requirements but this is misleading. ISO 9000 is no more a quality requirement than is ISO 1000 on SI units, ISO 2365 for Ammonium nitrate or ISO 246 for Rolling Bearings. The requirements of ISO 9000 are quality management system requirements – requirements for a quality management system.


ISO 9000 Standards – Design and development

ISO 9000 Standards – Design and development

Planning the design and development of a product means determining the design objectives and the design strategy, the design stages, timescales, costs, resources and responsibilities needed to accomplish
them. Sometimes the activity of design itself is considered to be a planning activity but what is being planned is not the design but the product.

The purpose of planning is to determine the provisions needed to achieve an objective. In most cases, these objectives include not only a requirement for a new or modified product but also requirements governing the costs and product introduction timescales (Quality, Cost and Delivery or QCD). Remove these constraints and planning becomes less important but there are few situations when cost and time is not a constraint. It is therefore necessary to work out in advance whether the objective can be achieved within the budget and timescale. One problem with design is that it is often a journey into the unknown and the cost and time it will take cannot always be predicted. It may
in fact result in disaster and either a complete reassessment of the design objective or the technology of the design solution. This has been proven time and again with major international projects such as Concorde, the Channel Tunnel and the International Space Station. Without a best guess these projects would not get off (or under!) the ground and so planning is vital firstly to get the funding and secondly to define the known and unknown so that risks can be assessed and quantified.

Design and development plans need to identify the activities to be performed, by whom they will be perform and when they should commence and be complete. One good technique is to use a network chart (often called a PERT chart), which links all the activities together. Alternatively a bar chart may be adequate. There does need to be some narrative in addition as charts in isolation rarely conveys everything required.

Design and development is not complete until the design has been proven as meeting the design requirements, so in drawing up a design and development plan you will need to cover the planning of design verification and validation activities. The plans should identify as a minimum:
- The design requirements
- The design and development programme showing activities against time
- The work packages and names of those who will execute them (Work
packages are the parcels of work that are to be handed out either internally or to suppliers)
- The work breakdown structure showing the relationship between all the parcels of work
- The reviews to be held for authorizing work to proceed from stage to
stage
- The resources in terms of finance, manpower and facilities
- The risks to success and the plans to minimize them
- The controls that will be exercised to keep the design on course
Planning for all phases at once can be difficult as information for subsequent phases will not be available until earlier phases have been completed. So, your design and development plans may consist of separate documents, one for each phase and each containing some detail of the plans you have made for subsequent phases.
Your design and development plans may also need to be subdivided into
plans for special aspects of the design such as reliability plans, safety plans, electromagnetic compatibility plans, configuration management plans. With simple designs there may be only one person carrying out the design activities. As the design and development plan needs to identify all design and development activities, even in this situation you will need to identify who carries out the design, who will review the design and who will verify the design. The same person may perform both the design and the design verification activities, however, it is good practice to allocate design verification to another person or organization because it will reveal problems overlooked by the designer. On larger design projects you may need to employ staff of various disciplines such as mechanical engineers, electronic engineers, reliability engineers etc. The responsibilities of all these people or groups need to be identified and a useful way of parcelling up the work is to use work packages that list all the activities to be performed by a particular group. If you subcontract any of the design activities, the supplier’s plans need to be integrated with your plans and your plan should identify which activities are the supplier’s responsibility. While purchasing is dealt with in clause 7.4 of the standard, the requirements also apply to design activities.
