3 Definitions Open Systems (DOD/SEI) An open system is a collection of interacting software, hardware and human components, designed to satisfy stated needs, with the interface specification of components fully defined and available to the public, maintained according to group consensus and in which the implementation of components are conformant to the specification. COTS (summary from Federal Acquisition Regulations) Customarily used for nongovernmental purpose and has been sold, leased or licensed to the general public Exists a priori (in a catalogue or price list) 3-T Sangiolo 8/7/2001
