Purpose : The purpose of the System Architectural Design Process is to identify which system requirements should be allocated to which elements of the system.

Activities : 6.4.3.3.1 et 6.4.3.3.2

List of outcomes : As a result of successful implementation of the System Architectural Design Process:
a) a system architecture design is defined that identifies the elements of the system and meets the defined requirements;
b) the system’s functional and non-functional requirements are addressed;
c) the requirements are allocated to the elements of the system;
d) internal and external interfaces of each system element are defined;
e) verification between the system requirements and the system architecture is performed;
f) the requirements allocated to the system elements and their interfaces are traceable to the customer’s requirements baseline;
g) consistency and traceability between the system requirements and system architecture design is maintained; and
h) the system requirements, the system architecture design, and their relationships are baselined and communicated to all affected parties;
i) human factors and ergonomic knowledge and techniques are incorporated in system design; and
j) human-centred design activities are identified and performed.

NOTE The System Architectural Design Process in this International Standard is a specialization of the Architectural Design Process of ISO/IEC 15288. Users may consider claiming conformance to the 15288 process rather than the process in this standard.
