Framgångsfaktorer vid konceptutveckling.

Sammanfattning: Saab Dynamics is a business unit of Saab AB that offers solutions, services and products for military operations. In Saab Dynamics product portfolio the rocket launcher Carl-Gustaf is included. Carl-Gustaf is a portable, recoil free and reusable weapon system. Saab Dynamics also manufactures ammunition to Carl-Gustaf which can be varied between with explosive effect, smoke grenades, illuminating and fine caliber. To respective type of ammunition there is dummy grenades which has the same appearance, weight and loading procedure with the difference that the grenade is inert.  Initiation to the study came from an identified need to update the fuze on Drill Round 545C. The project was made on Saab Dynamics facility in Karlskoga and the purpose was to generate feasible concepts of the fuze, including to generate production documentation of the final concept. Since a concept development process was going to be executed it was considered relevant to investigate how this process should be performed at the company. From this the question at issue has been formulated.  Which success factors can be identified at a concept development process at Saab Dynamics? In addition, a sub-goal with the study is to produce production documentation to the updated fuze of Drill Round 545C according to ISO 22081 and manufacture a physical prototype.  The study is split into two parts, a qualitative study with purpose of answering the issue, and a concept study with purpose to produce the final prototype. Through interviews with employees and a literature study, success factors have been identified. A total of five success factors was found, together with some specific situations where they have significant matter. The success factors are: Communication, Group Composition, Openness in the group, Process fitted according to the specific project and Focus on boundaries between sub-projects. The concept study was performed through a systematical method for construction and design, with distinct activities and decision points. Four concepts were generated from the method, where all of them was manufactured through additive manufacturing and tested. All of the concepts fulfilled the requirements and by decision matrixes a final concept was decided. From the chosen concept a physical prototype and production documentation was created. This concept fulfilled the set goals and thereby the result of the concept study is assumed successful. Reflections were made after the concept study regarding the success factors, as some of them would have positively affected the concept development process. In future investigations, evaluations of the current working methods at Saab Dynamics are recommended as this study had limitations to not evaluate these. The report also emphasizes the importance of spreading the knowledge and experience that exists, as a possible area of improvement.
