To test the expectation that model-based development improves control of costs and complexity in the development of software-intensive systems, Altran conducted a global study in cooperation with the Technical University of Munich. The results of this study reveal changes in costs, time, and quality due to the application of model-based techniques.

This presentation discusses:

• Specific results that indicate a considerable gain in efficiency using model-based software development
• Factors that distinguish efficient from inefficient software development using models
• The “frontloading effect,” in which efficiency is increased by early entry into testing

This presentation focuses on the development process for the on-board Scania Driver Support system.
