Saab is a global company that primarily operates in the defense industry. The study is conducted at the Project office within the Development Department at Saab Dynamics. In a GAP analysis carried out by Saab Dynamics, one of the company's processes has proved to be unclear. The process that has been noted as problematic concerns how Saab Dynamics receives, reviews and approves and stores technical documentation that accompanies incoming deliveries. The study aims to clarify how the Development Department and the Purchasing Department collaborate on the work step and clarify how quality assurance of required documentation takes place in the current situation and how it can be improved. In the study, theory of total quality management, organizational theory as well as processes and Lean have been used. The case study has a qualitative approach as the focus aims to get a holistic view of the working methods on a specific process at Saab Dynamics that has been studied. The method used to collect data is documentation review and interviews of employees at the company. The result describes an unclear division of responsibilities regarding the work step between the Purchasing and Development Department and there is no clear process for quality assurance of required documentation. In order to have an efficient process, Saab Dynamics needs to eliminate the variation and waste that currently exists. Finally, an implementation proposal is presented for a standardized process for the work step.
