|4 Regulations Submodel System Development
4 Regelungen Submodell Systemerstellung
While the three submodels Quality Assurance (QA), Project Management (PM) and Configuration Management (CM) describe the accompanying activities in a development project, the development itself is realized in submodel System Development (SD).
The structure of submodel SD is based on activities on two levels, i. e.
In these two levels, the step of the requirements analysis and the step of the design are differentiated.
- System (Segment) level and
- level of software and hardware units (SW Units/HW Units).
From the point of view of the system development process, these levels help in the early activities to get from abstract descriptions to software and hardware, and in the later activities they help to get from the software and hardware level to the overall System.
The following concepts and explanations have a central meaning for the understanding of the remainder of these regulations:
The formulations of the regulations assume that normally all developments are incremental. This means that the regulations of submodel SD- System Development attempt to show that a System is developed in increments (and possibly delivered and operated in increments as well).
SD1 - System Requirements Analysis
SD2 - System Design
SD3 - SW/HW Requirements Analysis
SD4 - Preliminary SW Design
SD5 - Detailed SW Design
SD6 - SW Implementation
SD7 - SW Integration
SD8 - System Integration
SD9 - Transition to Utilization
