This thesis was in collaboration with Saab AB Aeronautics and aimed to investigate the information requirements at Saab AB, and then to write at least one software specification for something that could facilitate planning and/or evaluation of flight missions. Today, different support systems are used at Saab AB to help with planning and evaluation of flight missions. The most commonly used is the Mission Support System, but systems external to Saab AB such as applications for tablets are also used. Through semi-structured interviews and an analysis of the interviews based on the Grounded Theory approach several ideas for what could be done to facilitate planning and/or evaluation emerged. Two ideas were looked closer at; a statistical overview over missions implemented in the Mission Support System and an integration of an external program called SkyDemon and the Mission Support System. The statistical conclusions could help with getting an easier overview over one or several missions, which facilitates evaluation and how to forward information about the mission. To integrate SkyDemon with the MSS is something that tries to fulfill the wishes about accessibility and having everything at the same place, making the planning of missions run easier and faster.
