Quality Management Systems
ISO 9000:2000 - Quality Management Systems Fundamentals and Vocabulary
ISO 9001:2000 - Quality Management Systems Requirements- Implementation of the most commonly used Quality Management System provides an organisation with a set of processes to ensure a common sense approach to the management of the organisation, such as consistency and improvement of working practices.
ISO 9004:2000 - Quality Management Systems Guidance
ISO 19011:2000 - Quality Management Systems Auditing
ISO 1000 series of QMS supporting standards
The term 'ISO 9000' is often used incorrectly. Properly used, it is the individual standard, ISO 9000:2000 - Quality Management Systems Fundamentals and Vocabulary.
When an organization is ISO 9001 registered (or 'certified'), it means that an auditor has checked and confirmed that it meets the requirements laid out in ISO 9001:2000. This is the only Standard in the family for which a third-party can issue registration. The logo opposite is the one displayed by the organizations that have gained registration through BSI.
Environmental Management Systems
ISO 14001:2004 - Environmental management systems - Requirements with guidance for use- An Environmental Management System provides a framework for managing environmental responsibilities of an organisation. They are based on standards that specify a process of achieving continuously improved environmental performance and compliance with legislation.

Information Security Management Systems
BS ISO/IEC 27000 – Fundamentals and vocabulary (to be published 2007/8)
BS ISO/IEC 27001 – Information security management systems – Requirements (published 2005)- An Information Security Management System (ISMS) is a systematic approach to managing sensitive information of an organisation so that it remains secure. It encompasses people, processes and IT systems.
BS ISO/IEC 27002 – Code of practice for Information security management (currently known as BS ISO/IEC 17799 but will be altered by ISO to 27002 in 2007)
BS ISO/IEC 27003 – Implementation guidance (to be published 2007/8)
BS ISO/IEC 27004 – Metrics and measurement (to be published 2007/8)
BS ISO/IEC 27005 – Information security risk management (to be published 2007/8)
The standard is currently published in the UK as three parts:
BS ISO/IEC 17799 (formerly BS 7799-1) Information technology. Specification for information security management.- This part is a code of practice that can be used by an organisation as a starting point for developing practices specific to their needs. It can be used to establish an organization’s guidelines and general principles for initiating, implementing and improving information security standards and effective security management practices, perhaps identified in a risk assessment
BS ISO/IEC 27001 (formerly BS 7799-2) Information technology. Security techniques. Code of practice for information security management- This part states requirements for implementing and operating an Information Security Management System. It provides a foundation for third-party audit and is written in a style that conforms with other management system standards, such as ISO 9001(Quality) and ISO 14001(Environment). It also introduces the Plan-Do-Check-Act (PDCA) process model as part of a management system approach to developing, implementing, and improving the effectiveness of an organisation's ISMS within the context of its overall business risks.
BS 7799-3 Information security management systems. Guidelines for information security risk assessment- gives guidance to support the requirements given in BS ISO/IEC 27001 regarding all aspects of an information security management system (ISMS) risk management cycle. This includes assessing and evaluating the risks, implementing controls to treat the risks, monitoring and reviewing the risks, and maintaining and improving the system of risk controls.
BS 7000 series- This is a series of standards for the management of design and can support the design of manufactured products, of services, of construction projects, for planning obsolescence in all stages of the life of products, and for managing inclusive design. There are currently seven standards in the series.
BS 7000-1:2008 Design management systems. Guide to managing innovation- Describes how senior executives within organizations can plan their products and services a significant time into the future - for three product/service generations. Research has revealed that organizations that evolve a framework for long-term innovation react faster to threats or surprises, are more likely to take effective action, and are better at sustaining the momentum of change. This standard puts forward a comprehensive framework and outlines how key issues might be tackled.
BS 7000-2:2008 Design management systems. Guide to managing the design of manufactured products- The success of business enterprises is built largely on their products, services and corporate reputations. Design has a critical influence on the conception and delivery of products that closely match the customers' needs and aspirations. This standard gives guidance on managing the design of manufactured products, and is relevant to all types of product and for every stage of manufacture from raw material through fabrication, delivery and use to ultimate disposal. It sets out the tasks and responsibilities in implementing an effective design policy for senior management, project managers, design managers and designers.
BS 7000-3:1994 Design management systems. Guide to managing service design- Service design is the formative stage of a service. It should be used to meet the reasonable and foreseeable requirements of the potential users of the service whilst using the available resources with economy. The concepts, principles and quality system elements described in BS 7000-3 are applicable to all forms of service, whether solely of a service character or in combination with the manufacture and supply of a tangible product. This can be shown as a continuum ranging from a situation where the service is directly related to a product to a situation where there is little product involved. The standard gives guidance on the management of the design of service at all levels, for all design organizations and all types of service.
BS 7000-4:1996 Design management systems. Guide to managing design in construction- This document gives guidance on management of the construction design process at all levels, for all organizations and for all types of construction projects. It is intended for those who work in, or interact with, the construction industry. Where general management principles are given, they may be adapted to suit any size of design organization or construction project. The guidance given covers the management of design activities throughout the life-cycle of a construction project, from the point when the client initiates a project.
BS EN 62402:2007 Obsolescence management. Application guide (previously BS 7000-5:2001)- Obsolescence affects all products and it impacts upon all stages of the life of products. The objective of obsolescence management is to ensure that obsolescence is managed as an integral part of design, development, production and in-service support in order to minimize cost and detrimental impact throughout the product life cycle. This Standard gives guidance for establishing a framework for obsolescence management and for planning a cost-effective obsolescence management process that is applicable through all phases of the product life cycle. It can be applied to all products that include electronic, electrical and electro-mechanical components, although its use can be extended to include other products and processes.
BS 7000-6: 2005 Design management systems. Managing inclusive design. Guide- Provides a comprehensive framework to help all enterprises, public sector and not-for-profit organizations introduce a professional approach to inclusive design. It concentrates on the management, not the practice, of inclusive design. It contains guidance at organization and project levels.
BS 7000-10:2008 Design management systems. Vocabulary of terms used in design management- Defines terms used in design and its management, and includes those that may have particular meanings when used in different areas of industry and commerce. It has been prepared to assist those who have a responsibility for or an interest in design and its management.
