This thesis is structured into two main parts: the theoretical and practical segments of the development of a web application for managing the error reporting process. In the initial section of the thesis, technologies, and tools used during the construction of the application are described in detail. Furthermore, illustrative diagrams are provided to elucidate the functioning of the application. This theoretical section culminates with a SWOT analysis, providing us with a comprehensive insight into the internal strengths and weaknesses of the application, as well as external opportunities and challenges that the application encounters. Moving forward, we focus on the practical aspect of the work - the implementation of the web application is presented, which constitutes the core of the practical segment of this master's research. Finally, the thesis concludes with user instructions designed to facilitate users' utilization of the application. The application has been successfully implemented in more than thirty Croatian hospitals and has more than four hundred satisfied users.
