Systems engineering is an interdisciplinary approach and a set of practices that ensure the implementation of successful systems. Systems engineering is inseparably linked to project management and enterprise management. The systems engineer, first and foremost, plays the role of the task manager, leading up to the engineers of various specialties consistent requirements and constraints from various of stakeholders (users, investors, suppliers, regulators, etc.), as well as the main engineering decisions (architecture ).
Systems engineer is the one who is responsible for ensuring that feasibility studies, technical assignments, private technical tasks, programs and test procedures, operational and other documents that serve as tasks for a wide range of specialists, consistently describe the system. While improvement and development of some characteristics of the system in the course of its life cycle would not worsen other characteristics.
