TC 3 BACKGROUND

AC/7/2004 System approach in IEC standardization

Need to include system aspects in IEC standardization as result of changes in the market place

A need to achieve a certain change of culture in the technical (sub-)committees TC’s with System function (TCS’s); and TC’s with Product function (TCP’s)

Relations between TCS’s and TCP’s – reciprocity – mutual recognition of roles

TC 3 THE SYSTEM APPROACH

The system approach concept

concept that considers that functional and structural engineering, system-wide interfaces and compositional system properties become more and more important due to the increasing complexity, convergence and interrelationships of technologies

TC 3 THE SYSTEM APPROACH

A system and its environment

3(Cape Town/Secretariat)6: 9

TC 3

TC with System function (TCS)

Specifies the overall performance independent of methods of implementation

Specifies requirements on components from the system perspective

When specifying the requirements on the components referring to product standards if existing

Informs the relevant TCP if none exists Develops solutions in such cases in co-operation

with relevant TCP (published as a product standard or a system/component standard)

THE SYSTEM APPROACH

3(Cape Town/Secretariat)6: 10

TC 3

TC with Product function (TCP)

Specifies products independently of all possible applications

Refers to system standards, when applicable Provides information to TCS’s on proper

application, proper referencing, etc Discusses the requirements with the TCS’s in

order to meet the system requirements. This may be done by Introducing requirements in existing standards Creating a suitable class of product for the required

component Creating a new standard

Interpretation for documentation

A “system standard” would be a specification of the properties and components of a Documentation System usable for specified kind of objects

A “product standard” would be a specification of a specific aspect of the documentation system or the properties of a system for a delimited branch or technology (sub-system) usable within the overall system.

The IEC/ISO Documentation system?

TC 3

Objective of the documentation system

To provide a coherent set of standard concepts and specifications that governs a user to produce information/documentation of any kind of industrially produced object, fulfilling general and specific requirements for information during the whole life cycle of that object (including records for its existence after the life cycle end).

Components of the documentation system

Concepts and terms Specifications for preparation of documentation

structuring of documentation (“information model”) document kinds identification, classification, etc

Specifications for maintenance of the information document management change management archiving

Specifications for distribution/delivery of documentation Separate documentation on-site documentation

Etc.

Questions for discussion

Does an approach of this kind add value to our work?

Do we need an overall description of the system in which our standards are supposed to fit?

How far are we today? What more would we need to do?

Possible continuation

A new series of publications: IEC-ISO 82nnn: IEC/ISO Documentation system Part 1: Principles and rules Part 2: TR Application example for XYZ Part 3: TR Application example for PQR Part n: …

Develop idea as Stage 0 work NWIP with rough overall structure and a more

detailed structure for Part 1 ?
