• System is collection of inter-related components.System is collection of inter-related components.

• Engineering means designing of complex objectives. Engineering means designing of complex objectives.

• Therefore SYSTEM ENGINEERING is defined as Therefore SYSTEM ENGINEERING is defined as collection of inter-related components for designing of collection of inter-related components for designing of complex objectives & then to achieve that objectives. It complex objectives & then to achieve that objectives. It denotes different things to different people.denotes different things to different people.
