Today, modern software systems are often component-based. In addition to numerous advantages, this also brings some disadvantages. One of them is that the teams involved often work in different issue management systems. Therefore, it is a challenge to communicate related issues across components in the different teams. Problem. Although Gropius, as a cross-component issue management system, offers a solution to this problem, no company is currently using it. Therefore, it must be made easier for them to get started with Gropius. Objective. Some of the functions of Gropius are to be integrated directly into the user’s issue management system, with which the user is already familiar. The objective here is to create and evaluate the concept as well as a prototype of this idea. Method. To do this, a browser extension is used to manipulate the display of webpages from issue management systems such as GitHub and Jira, and to integrate additional functionality from Gropius into it. The creation of a concept, as well as the evaluation of it and the prototype is carried out in close cooperation with stakeholders. Result. In the evaluation of the elaborated concept, as well as the implemented prototype, it became clear that the idea is evaluated as helpful by the experts and that an integration of the Gropius functions into the issue management system used by the experts is desired. Conclusion. The main contributions of this thesis are the detailed requirements, a concept and a prototype for the Gropius Browser Extension as well as the evaluation of the concept and the prototype through an expert survey.
