1. ISO/IEC JTC 1/SC 7
Working Group 42
- Architecture
Johan Bendz

2. ISO/IEC JTC 1 – Standardization in the field of Information Technology
JTC1 is the ISO and IEC* joint technical committee for IT-related standards
Mission statement:
Develop, maintain, promote and facilitate IT standards required by global markets meeting business and user requirements concerning:
design and development of IT systems and tools
performance and quality of IT products and systems
security of IT systems and information
portability of application programs
interoperability of IT products and systems
unified tools and environments
harmonized IT vocabulary
user friendly and ergonomically designed user interfaces
* International Electrotechnical Commission

3. ISO/IEC JTC 1 - Structure
Exemples of subcommittees are:
SC 06 "Telecommunications and information exchange between systems"
SC 07 “Systems and Software Engineering”
SC 22 "Programming languages, their environments and system software interfaces"
SC 27 "IT Security techniques"
SC 29 "Coding of audio, picture, multimedia and hypermedia information"

4. ISO/IEC JTC 1/SC 7 – Systems and Software Engineering
Exemples of working groups arer:
WG 2 - Development of standards for the documentation of software and systems.
WG 6 - Development of standards for software products evaluation and metrics for software products & processes.
WG 7 - Development of standards on Life Cycle Management.
WG 10 - Development of standards and guidelines covering methods, practices and application of process assessment …
WG 19 - The development of standards to enable the integration of business and IT system specifications, and to facilitate the provision of software and system engineering tools and techniques to implement information systems.

5. ISO/IEC JTC 1/SC 7 – WG 7 – Life Cycle Management
Exemples of standards produced are :
ISO/IEC 12207: Software Life Cycle Processes
ISO/IEC 15288: Systems Life Cycle Processes
Swedish experts have been instrumental in the development of these standards
ISO/IEC has formed the basis of the FMV process orientation since 2000

6. ISO/IEC JTC 1/SC 7 Working Group 42 – Architecture
A new WG within SC7, constituted by ballot closing
Convener – Johan Bendz, Sweden
Secretariat managed by SIS i Stockholm
Initial project:
Joint review (w/ IEEE) of ISO/IEC IEEE Recommended Practice for Architectural Description of Software-Intensive Systems

7. ISO/IEC JTC 1/SC 7/WG 42 – WG Number and Title
Proposal:
WG 42 – Architecture
Rationale:
The number 42 is explained to be “the answer to everything” in neo-classic literature. The concept of Architecture is known to have similar aspirations.

8. ISO/IEC JTC 1/SC 7/WG 42 – Terms of Reference
Proposal:
The life cycle management of standards created to facilitate the development and use of architecture-related concepts, models and methods for systems and services.
The architectures addressed may pertain to a range of systems and services at different levels of abstraction or complexity. Examples of these may be
Enterprises (businesses)
Technical system elements (product aggregates)
Individual software components (products)

9. ISO/IEC JTC 1/SC 7/WG 42 – Terms of Reference
Rationale:
The engineering discipline of Systems Architecture (or Systems Architecting) has evolved side by side with other engineering disciplines pertinent to software and systems.
There have been concerns that even though architecture holds promise to deliver added value to the life cycle management of systems and services, the concepts associated with architecture are not used in a consistent fashion and their relationships to seemingly similar concepts in other engineering disciplines is not clear or well understood.
It is in the interest of SC7 to accommodate architecture as a discipline and to provide standards in this particular area of growing importance to industry and World trade. The Architecture discipline addresses the management of key properties of systems and services, required to ensure e.g. integrity, interoperability and reusability, and is therefore very much in line with the respective scopes of JTC1 and SC7.

11. ISO/IEC JTC 1/SC 7/WG 42 – Work Meetings
WG 42 will convene co-located with WG 7:
Interim Meeting - October 2006 – Seoul, Korea
Annual Plenary - May 2007 – St. Petersburg, Russia
Interim Meeting - October 2007 – Montreal, Canada
Annual Plenary - May 2008 – Berlin, Germany

12. ISO/IEC JTC 1/SC 7/WG 42 – Work Program
WG 42 will at first address the following issues:
Project #1: The joint revision of ISO/IEC IEEE 1471
Step 2 of the “Fast-Track” procedure
Document structure ISO/IEC 42000
IS/TR on ”ISO/IEC Architecture Belief System”
IS/TR on Concepts and Terminology for Architecture Practices
TBD
WG 42 is NOT about standardized architectures for specific domains

13. ISO/IEC JTC1/SC7/WG42 – 42000 document series
WG 42 will publish standards on Architecture in the series.
Proposed document structure:
ISO/IEC TR – Architecture – Concepts and Terminology
ISO/IEC TR – TBD
ISO/IEC STD – New # of ISO/IEC (IEEE 1471)
ISO/IEC STD TBD
