Redesign of the collaborative planning system

This thesis deals with the development of a new design for a collaborative planning system, used both commercially, and in the Hydronaut shuttle mission planning. The system, called CommonTongue, allows for the creation of a hierarchy of tasks, each having its own set of associated data. The goal is to visualize that data and allow the user to efficiently plan their events in collaboration with other users online. During the course of the thesis, CommonTongue was examined from the perspective of a new user, with three rounds of user tests being used as the basis for the final design. The findings of these examinations were then used to identify fundamental design issues, which negatively impacted the performance of the system. These issues were addressed with a redesign of the main application view and the main interface used to modify data in the system. The interface changes follow fundamental design principles, and aim to make the system intuitive and readable.
