Appendix: link to main standards
Architecting complex systems

Some of the processes involved in architectural design are mentioned in at least two standards:

• ISO/IEC/IEEE 15288 (Systems and Software Engineering – System lifecycle processes) ;

• ISO/IEC/IEEE 42020 (Enterprise, Systems and Software – Architecture-related processes).

We won't provide an overview of these standards, just a brief introduction, and we'll refer to them directly to position the various activities introduced.

The standard ISO15288 defines a set of engineering processes that support the life cycle of artificial systems. However, it does not explicitly define systems engineering or a systems engineering process (or approach),...
