Cross-Domain Dependency Modelling - How to achieve consistent System Models with Tool Support

Embedding and integrating functionalities from different domains has led to a significant increase in information that developers have to deal with. It is hardly possible to oversee implications of activities like change requests since influenced components from other domains are difficult to identify. This calls for an approach that supports product developers with methods and tools helping to analyse, control and primarily build up complex systems and the interdependencies between their comprising models from various domains. The focus of the presented approach, developed in the project ISYPROM, is the integration and connection of different partial models, used in product development. In doing so, implications of changes become evaluable, potential errors can be identified and information presented to the developer can be reduced. Special emphasis has been put on models describing requirements, functionalities, product structures and especially their interdependencies. Methods and tools focus on usability, information reduction and quality aspects.
