The interest in the complex relationship between the behaviour of users and the design of interactive system has been significantly increased as the digital technology has advanced. This has led to usability becoming one of the key elements in user-centred interaction design. Systems need to be designed in a usable way; efficient, use-enhancing, flexible and learnable and the design should also meet the user’s needs and aspirations. This thesis aimed to develop a more usable prototype of the Maintenance Ground Support System (MGSS), using prototyping and a user-centred design approach. The prototype was developed using an adaptation on the evolutionary software development process that consisted of four iterative steps. The prototypes were created, tested and evaluated with surrogate and end-users. The design of the prototype is based on a customizable and simple dashboard application that supports multiple user needs and requirements, in a familiar environment where the user can feel confident and be in control. Based on usability testing, the prototype was concluded to be more efficient, understandable as well as easier to use than the existing system.
