The Similarity between ISO 9001 and BS 7799-2

The Similarity between ISO 9001 and BS 7799-2
BS 7799-2:2002 is a specification for an Information Security Management System (ISMS). It is shortly to be upgraded to the status of a full
International Standard, and published as ISO/IEC 27001. The normative part of this standard has four sections and an annex . The requirements of the four sections are associated with the PDCA cycle. The annex defines all the controls that must be considered for generating the SOA. Thus the structure of BS 7799-2:2002, as will be ISO/IEC 27001, can be simply described as:
A PDCA framework;
An SOA.
ISO 9001:2000 is a specification for a Quality Management System (QMS). The normative part of this standard has five normative sections,
numbered 4 – 8. All of these requirements must be met in order to claim conformance with the standard, save for section 7 (Product Realisation),
where the standard states in paragraph 1.2 “Where exclusions are made, claims of conformity to this International Standard are not acceptable unless
these exclusions are limited to requirements within clause 7, an such exclusions do not affect the organisation’s ability, or responsibility, to provide
product that meets customer and applicable regulatory requirements”.
In Table 2 we relate the requirements of sections 4, 5, 6 and 8 to the PDCA framework. We treat section 7 as an SOA.
The BS 7799-2:2002 standard gives instruction on how the controls documented in BS 7799-2 Annex A are to be determined as being applicable or nonapplicable. In particular, if the control is applicable it must be justified in terms of the results of a risk assessment.
The controls listed in Section 7 of ISO 9001 may be excluded with justification. Thus, Section 7 of ISO 9001 may be treated in exactly the same manner as BS 7799-2 Annex A provided that applicable quality controls are also justified by
reference to a risk assessment. Conversely for an integrated MS, information security controls that are declared to be non-applicable should also be
justified as not applicable by reference to a risk assessment, in order to bring the two standards into line. Interestingly, this requirement was present in
BS 7799-2:1999 but was dropped in the 2002 revision.
The amalgamation of these two approaches in an integrated MS should not be seen as a disadvantage. The justification of non-applicable information security controls greatly simplifies the task of determining, given a change of threat or
business practice, whether a non-applicable control has now become applicable. The justification of Product Realisation controls by way of a reference to a risk assessment serves to remind us that, for many organisations, quality controls are not uniform across the whole organisation but are commensurate with the degree of risk involved.
For example, in the software business, a fixed price assignment with tight timescales to produce a bespoke software system has a greater risk than a
time and materials contract to supply programming staff, and the quality controls applied to management planning and reporting of the two projects would be very different.

Quality Planning

Whenever the term “product” is used within the ISO 9001 standard, it refers to both tangible goods and intangible services. The ISO 9001 standard is meant to be generic which means that it is suitable for all kinds of organization, whether commercial or otherwise. The purpose of the quality management system model that is being propagated by the standard is the fulfillment of customer requeirements and expectations in order to induce high levels of customer satisfaction. An unsatisfied customer is essentially a customer whose requirements or needs, and expectations of the level of services being granted upon him/her have not been met. We are all customers because we buy products all the time. So we know what it means to be a dissatisfied customer. The common reaction is to never to go back to that seller and look for other alternatives. A successful organization is one which understands what it takes to meet customer requirements in order to satisfy their needs and expectations. A specific process is thus necessary to resolve any customer complaint or dispute. This process should be geared towards satisfying the customer’s needs and expectations. The parameters of this process should be referenced from the terms of the sale and purchase. This is why it is necessary to review the customer’s requirements before committing to the sales contract. It is necessary that the customer understands what he/she is paying for and it is equally necessary for the organization to understand what it is supposed to deliver. When your organization has these processes in place, then the only thing to do next is to continually measure the effectiveness and subsequently take actions to continually improve the whole process.

Concept of quality – historical background

Concept Of Quality – Historical Background
The concept of quality as we think of it now first emerged out of the Industrial Revolution. Previously goods had been made from start to finish by the same person or team of people, with handcrafting and tweaking the product to meet ‘quality criteria’. Mass production brought huge teams of people together to work on specific stages of production where one person would not necessarily complete a product from start to finish. In the late 1800s pioneers such as Frederick Winslow Taylor and Henry Ford recognized the limitations of the methods being used in mass production at the time and the subsequent varying quality of output. Taylor established Quality Departments to oversee the quality of production and rectifying of errors, and Ford emphasized standardization of design and component standards to ensure a standard product was produced. Management of quality was the responsibility of the Quality department and was implemented by Inspection of product output to ‘catch’ defects. Application of statistical control came later as a result of World War production methods. Quality management systems are the outgrowth of work done by W. Edwards Deming, a statistician, after whom the Deming Prize for quality is named.
Quality, as a profession and the managerial process associated with the quality function, was introduced during the second-half of the 20th century, and has evolved since then. Over this period, few other disciplines have seen as many changes as the quality profession.
The quality profession grew from simple control, to engineering, to systems engineering. Quality control activities were predominant in the 1940s, 950s, and 1960s. The 1970s were an era of quality engineering and the 1990s saw quality systems as an emerging field. Like medicine, accounting, and engineering, quality has achieved status as a recognized profession.
