DIN EN 9277:2015-12

Systems engineering is increasingly being used to develop and implement complex technical systems. Systems engineering considers the system as a whole and in all situations of its lifecycle. It provides a framework for combining various technical disciplines (electronics, data processing, mechanics, ergonomics and so on) and some enterprise functions (design, production, logistics, tests and so on) without necessarily intervening in these disciplines and functions. It aims for the overall optimization of the solution in a field of constraints (costs, schedule, performance, strategy, and so on) established by the Programme management and guarantees consistency between all components of the solution (functional and physical interfaces). EN 9277 is intended to help the acquirer and the organization to establish management requirements for SE activities and to help the supplier to construct the elements of the management plan. This standard applies to the various levels of the product tree for the products that can be considered as systems: - in the general case of a supplier, which with the help of one or more suppliers, develops a system on behalf of an acquirer; - in the case of an integrated team (sharing of SE roles, responsibilities and risks). This document constitutes a guide illustrating the requirements and possible responses for SE management. It can be used as a checklist which should be adapted or completed according to the specific context of each project. The standard addresses current challenges of the programmes such as the multi-projects approach, the multi-disciplinary approach, new methods of acquisition, the increasing complexity of systems to be acquired, the evolving aspects of the system and its incremental development, the complexity of the management of projects in terms of organization, and the evolution of the industrial sectors. In this document the system considered comprises a target system and elements (products, processes, etcetera) needed for developing, producing and using it, in other words a range of end products and products supporting the lifecycle of the target system. The case where the system is only an element of the service provided (no system is acquired, service only) is not addressed in this document. The AeroSpace and Defence Industries Association of Europe - Standardization (ASD-STAN) has been declared responsible by the European Committee for Standardization (CEN) for preparing European Standards (EN) for the aerospace sector. This document has been prepared by ASD-STAN, Technical Section General. The responsible German standardization committee is 131-05-01 AA "Grundlagen und Managementverfahren (Spiegelausschuss zu ISO/TC 20/SC 14)" ("Basic principles of management processes (Mirror committee of ISO/TC 20/SC 14)") at DIN Standards Committee Aerospace (NL).
