This diploma thesis focuses on the difference between management and engineering. These two disciplines use different models, which obviously have different fields of expertise and due to this specialization use a different language each with their own terminology and idioms - especially engineering.
The goal of this diploma thesis is to combine management and engineering processes in using one model. Therefore a meta-model, which is then mapped onto an existing process model, is developed. This meta-model has defined processes and defined interfaces between management and engineering. There are also defined requirements and deliverables for both - management and engineering.
The second part of this diploma thesis covers the application and integration of the proposed extension into already existing processes and projects of a small development team. The application and integration are tested in a case study, which is performed in a software development project in an academic context. As a result, the team and also companies, who use this extension, would have one model, which covers the whole procedure, starting from the idea for a new product to the final rollout. All these steps are covered in this model and ensure a certain level of quality.
