Delivery Process: ENG.3 System architectural design
The purpose of the System architectural design process is to identify which system requirements are to be allocated to which elements of the system.

Activity diagram: ENG.3 System architectural design ENG.3.BP1: Define system architectural design ENG.3.BP2: Allocate System Requirements. ENG.3.BP3: Define Interfaces. ENG.3.BP4: Develop verification criteria. ENG.3.BP5: Verify System Architectural Design. ENG.3.BP6: Ensure consistency and bilateral traceability of system requirements to system architectural design. ENG.3.BP7: Communicate system architectural design. Assess Generic Practices Capability Level 5 Assess Generic Practices Capability Level 4 Assess Generic Practices Capability Levels 1,2 and 3

As a result of successful implementation of this process:

ENG 3.1 a system architectural design is defined that identifies the elements of the system and meets the defined systems requirements

ENG 3.2 the system requirements are allocated to the elements of the system

ENG 3.3 internal and external interfaces of each system element are defined

ENG 3.4 verification between the system requirements and the system architectural design is performed

ENG 3.5 consistency and bilateral traceability are established between system requirements and system architectural design

ENG 3.6 the system requirements, the system architectural design, and their relationships are baselined and communicated to all affected parties

Key Considerations

NOTE : Definition of system architectural design includes development of verification criteria. Verification criteria define the qualitative and quantitative criteria for verification of a requirement. Verification criteria demonstrate that a requirement can be verified within agreed constraints.
