The design process is a user centered process and the new design is based on the user’s needs, routines and the workflows where {CAPS} is used as a tool. The new design should increase the usability and streamline the user’s workflows. In the analysis the user’s needs is mapped by user research, where the users are observed using the existing system. The key findings are that the users work in several workspaces, they use a lot of time navigation to different screens, and there is no help memorizing data. The user needs and observations are mapped into the actual requirements for the design. Different solutions are discussed and the most suitable, a solution, where all changes can be done from one page and where workspaces are incorporated, is chosen. A conceptual design is created to fulfill the requirements and a prototype is implemented. The prototype is evaluated by conducting some usability tests and an expert evaluation. These evaluations show that the new user interface generally meets the requirements and points out some issues for the further development. Also a small test comparing the prototype and {CAPS} were performed, and this test clearly shows improvement in the time used completing a task using the prototype." }
