Systems Engineering Is...
Systems engineering consists of two significant disciplines: the
technical knowledge domain in which the systems engineer operates, and systems
engineering management. This book focuses on the process of systems engineering
Three commonly used definitions of systems engineering
are provided by the best known technical standards that apply to this subject.
They all have a common theme:
° A logical sequence of activities and decisions that transforms an
operational need into a description of system performance parameters and a
preferred system configuration. (MIL-STD-499A, Engineering Management, 1
May 1974. Now cancelled.)
° An interdisciplinary approach that encompasses the entire technical
effort, and evolves into and verifies an integrated and life cycle balanced set
of system people, products, and process solutions that satisfy customer needs.
(EIA Standard IS-632, Systems Engineering, December 1994.)
° An interdisciplinary, collaborative approach that derives, evolves,
and verifies a life-cycle balanced system solution which satisfies customer
expectations and meets public acceptability. (IEEE P1220, Standard for
Application and Management of the Systems Engineering Process, [Final
Draft], 26 September 1994.)
In summary, systems engineering is an interdisciplinary engineering
management process that evolves and verifies an integrated, life-cycle balanced
set of system solutions that satisfy customer needs.
