5.3.10 System Design

The »Discipline System Design includes »Work Products and »Activityies supporting the architectural design and defining a suitable development process.

In the V-Modell, the architectural design is developed at two hierarchy levels - the level of the system or »Enabling System and the unit level. The preliminary design and the design decisions are documented in specific architectural documents. The development process and the integration and evaluation process are specified in the appropriate implementation, integration and evaluation concepts.

Architectural documents and implementation, integration and evaluation concepts are closely connected. It must be possible to develop all system, hardware and »Software Elements identified in the architecture by using the respective implementation, integration and evaluation concept. In addition, system architecture and integration architecture must be consistent in order to ensure the correct implementation of architectural decisions.

The discipline System Design includes an additional product especially for migration projects - the so-called »Migration Concept. This concept specifies the mapping of the legacy system and the new system and the execution of the migration.
