Method and arrangement for performance prediction of an information technology system

The invention consists essentially in the fact that already in the design phase reliable tests carried out by an automatic generation of a comprehensive performance prototypes in the real target environment of the system. For this purpose, the system design in a special notation, such as UML to enrich important performance information. A generator program then automatically generates the source code of the components involved, which are then transferred to the respective target platforms and systems, and where it activates (deployment) are. In addition, test scenarios can be generated with which the finished prototype system can be tested. The main advantage of the invention lies in the automatic, fast, flexible, efficient and consistent generation of an extensive prototypes, which would be impossible with manual prototypes. This allows for early and integrated design of hardware and software, thereby reducing the risks cost and time of a particular system / product development.
