Over the years, DSI-AS has developed a quality management system (QMS) based on ISO 9001:2015 which is specifically adapted to our main areas of activity in aerospace and information security. The QMS permeates all aspects of DSI's management structure and core project life cycle processes ranging from pre-development and requirements analysis to design, implementation, verification and supporting processes, as well as of course quality assurance. Through the application of the QMS, a high level of organisational clarity and effective project control are achieved.
