In this 7.5 HEC B-level thesis in Computer Science, a service desk web application is designed for Swedish government agencies with integrated major incident reporting functionality to the Swedish Civil Contingencies Agency (Myndigheten för samhällsskydd och beredskap). There are several advantages to integrating the major incident reporting procedure into the regular incident management process - information would no longer have to be duplicated, and the problems of untraceability and under-reporting could additionally be solved. The proof-of-concept application was designed and partially developed with ASP.NET Core (MVC) web framework and Bootstrap front-end framework. The user interface was evaluated with heuristic evaluation by the author and two master’s students in Information Security at Luleå Technical University. Although the proposed software and interface design may have left room for improvement, it did highlight the societal need for an efficient and responsible incident management process and the general benefits of integration.
