5.3.10.8 Enabling System Implementation, Integration, and Evaluation Concept

Process module: System Development

Responsible: System Architect (when using process module System Development)

Activity: Preparing Enabling System Implementation, Integration and Evaluation Concept

Participating: System Integrator, Hardware Developer, Logistics Manager, Software Architect, Safety Manager

Purpose

The »Enabling System Implementation, Integration, and Evaluation Concept defines the realization and completion process for an enabling system. It provides particularly the »System Integrator and the »Inspector with guidelines for their tasks.

The concept describes procedures, tools and environments for installation, integration and tests of system elements and enabling systems in detail. At system level, the integration is based on the units developed within the scope of hardware and software development and the implementation of external units identified in the architecture. Depending on the complexity of the realization process or the heterogenity of the enabling system to be developed, the concept may cover the entire system development or deal exclusively with the higher hierarchy levels down to unit level. In the latter case, an individual concept will be prepared for the development of Hardware and »Software Units.

The contents of the enabling system implementation, integration and evaluation concept shall be consistent with the corresponding architecture. The design decisions made shall be implemented in a suitable manner. With respect to organization and framework conditions, the concept is determined by specifications in the Project Manual. For the scheduling of the integration and evaluation process, the concept shall be coordinated with the »Integration and Evaluation Plan System Elements in the »Project Plan.

The »System Architect is responsible for the preparation of the concept. He will be supported by the system integrator, who is finally reponsible for the completed system.

Integration and evaluation require a balanced strategy with regard to acquirer specifications, available integration and demonstration assets and the minimization of redundancies regarding the necessary compliance demonstration activities.

Normally, the environment to be used will be described in this concept. However, if an environment is required for the long-term support of the system life cycle, the environment shall be realized as independent »Enabling System.

Depending on the evaluation specifications, the test products for the individual system elements will be prepared.

5.3.10.8.6 Safety and Security Relevant System Elements and Safety and Security Measures

For every system element (the system itself or the system elements that will emerge during the decomposition), it shall be determined if it has a risk potential, how high is this risk potenital with regard to functional safety and security, to which safety and security level (sometimes also called criticality level, assurance level or evaluation assessment level) it belongs and whether the execution of a »Safety and Security Analysis is required. The safety and security requirements to be fulfilled will be derived from the specification of the system element.

System elements critical for system safety and security are elements which are of critical importance for fulfilling the safety and security requirements, i.e., the risk assessment/danger potential of which exceeds a prespecified threshold level.
