Overview
Figure 33: Process module System Development
Purpose
The »Process Module System Development defines the basic skeleton of system development which is the basis for additional process modules as Software Development and Hardware Development. The software and »Hardware Unit s defined in the system architecture will be realized in the process modules Software Development and Hardware Development. In addition off-the-shelf products or results from subcontracts can be integrated during the system integration.
For this purpose, the process module includes activities and products required for creating a system and the appropriate »Enabling System. The system is subdivided into the system elements »Segment and software, hardware and »External Unit . The enabling systems support the systems during the life cycle phases and ensure the operation of the system within the respective operational environment.
(In accordance with »ISO/IEC 12207 ) The system is defined as a uniform whole, capable of fulfilling specified requirements or achieving certain objectives. It is the subject matter of the order agreed between acquirer and supplier. This means that a segment or a »Software Unit may be the subject matter of an order and, thus, of the system.
In the »Overall System Specification, the system development requirements are derived from the user requirements, which are part of the »Contract, defined more precisely and transfered to the system, the enabling system and the logistic support. Based on the requirements, the system architecture, the »Enabling System Architecture and the appropriate »System Specifications will be prepared. Similarly, integration - including the assembly and quality assurance for the integration procedures - is defined in parallel to the system design. Based on these integration concepts, the system and the enabling systems will be integrated from the system elements. The system elements characterize the actually developed products, e.g., an automobile, aircraft or database.
