Definitions of System

Definition
• A complete system includes all
equipment, related facilities, material,
software, services, and personnel
required for its operation and support to
the degree that it can be considered a
self-sufficient unit in its intended
environment

Definitions: MIL-STD-499
• A composite of equipment, skills, and
techniques capable of performing and/or
supporting an operational role

EIA/IS-632 Definition of a
system
• An integrated composite of people,
products, and processes that
provide a capability to satisfy a
stated need or objective
