What is Systems Engineering Systems engineering is a discipline that concentrates on the design and application of the whole(system)as distinct from the parts.It involves looking at a problem in its entirety,taking into account all the facets and all the variables and relating the social to the technical aspect. Systems engineering is an iterative process of top-down synthesis,development,and operation of a real-world system that satisfies,in a near optimal manner,the full range of requirements for the system.
