Increasingly complex demands on functionality and quality of software
systems and higher application dynamics require a fundamental change in
the software development process. A shift from personnel intensive
individual software development to capital intensive industrial
software production must take place. This could only be achieved by
utilizing tools supporting the development process and by planned
design and production of generally applicable and reusable components.
The AUGUSTA system (Ada Units Generalization Utility and Systems
Tailoring Assistant) concentrates on the aspect of reusability. It
allows the instantiation of programs from generic components and the
composition of complete application systems based on an equally generic
application structure. Furthermore, the AUGUSTA approach postulates a
special process model including a particular concept for user roles
according to their experience and tasks in the software construction
process.

This paper explains how the AUGUSTA system would support software
development based on component integration, prototyping and reuse. It
demonstrates the approach using an example from the domain of electric
power plants.
