This thesis project, conducted in collaboration with Scandinavian Airlines (SAS), investigates how safety-critical internal systems can be designed to enhance usability and user experience through an examination of the Aerodrome Approval system at SAS. Employing a research-through-design approach and utilizing heuristic evaluations, semi-structured interviews, contextual inquiries, and a redesign process, several guidelines for improving usability and user experience have been identified. Key insights reveal that optimizing login functionalities can enhance security and role-specific access, thereby reducing errors and improving the user experience. Consistency in design elements and adherence to standards play a critical role in usability, aiding in error prevention and improving system navigation efficiency. Additionally, effective strategies for error prevention, such as contextual warnings tailored to specific conflicts, help maintain workflow efficiency and prevent user fatigue, whereas ensuring a balanced and timely presentation of information is essential to prevent information overload while still ensuring access to critical data. The project illustrates how multiple usability principles are interconnected yet sometimes conflicting and emphasizes the need to further investigate safety-critical internal systems to a broader extent to be able to identify more generalizable design guidelines in the future.
