4 Definíciók SYSTEM A collection of interacting items organized to accomplish a specific function or set of functions within a specific environment [Automotive SPICE V3.1] set of elements (1.32) that relates at least a sensor, a controller and an actuator with one another [ISO26262] NOTE 1 The related sensor or actuator can be included in the system, or can be external to the system. NOTE 2 An element of a system can also be another system. ELEMENTS [ISO26262] system (1.129) or part of a system including components (1.15), hardware, software, hardware parts (1.55), and software units (1.125) COMPONENTS [ISO26262] non-system (1.129) level element (1.32) that is logically and technically separable and is comprised of more than one hardware part (1.55) or of one or more software units (1.125) NOTE A component is a part of a system.

11 SYS.3 System Architectural Design process description PURPOSE: establish a system architectural design and identify which system requirements are to be allocated to which elements of the system, and to evaluate the system architectural design against defined criteria. PROCESS OUTCOMES: 1. a system architectural design is defined that identifies the elements of the system; 2. the system requirements are allocated to the elements of the system; 3. the interfaces of each system element are defined; 4. the dynamic behavior of the system elements is defined; 5. consistency and bidirectional traceability are established between system requirements and system architectural design; and 6. the system architectural design is agreed and communicated to all affected parties.

12 SYS.3 System Architectural Design BP BP.1 BP.2 BP.3 Develop system architectural design. Develop and document the system architectural design that specifies the elements of the system with respect to functional and non-functional system requirements. [OUTCOME 1] Allocate system requirements. Allocate the system requirements to the elements of the system architectural design. [OUTCOME 2] Define interfaces of system elements. Identify, develop and document the interfaces of each system element. [OUTCOME 3] BP.4 Describe dynamic behavior. Evaluate and document the dynamic behavior of the interaction between system elements. [OUTCOME 4] BP.5 Evaluate alternative system architectures. Define evaluation criteria for the architecture. Evaluate alternative system architectures according to the defined criteria. Record the rationale for the chosen system architecture.

13 SYS.3 System Architectural Design BP BP.6 Establish bidirectional traceability. Establish bidirectional traceability between system requirements and elements of the system architectural design. [OUTCOME 5] BP.7 BP.8 Ensure consistency. Ensure consistency between system requirements and the system architectural design. [OUTCOME 1, 2, 5, 6] Communicate agreed system architectural design. Communicate the agreed system architectural design and updates to system architectural design to all relevant parties.
