engineering
- The design of a complete system including hardware and
software as distinct from the design of a single
component.
- A logical sequence of activities and decisions
transforming an operational need into a description of
system performance parameters and a preferred system
configuration. (US DOD MIL-STD 499A)
- The application of scientific and engineering effort to:
a) Transform an operational need into a description of
system performance parameters and a system configuration
through the use of an iterative process; e.g. definition,
synthesis, analysis, design, test and evaluation, etc
b) Integrate related technical parameters and assure
compatibility of all physical, functional and program
interfaces in a manner which optimises the total system
definition and design and
c) Integrate reliability, maintainability, safety, human
and other such factors into the total engineering effort.
(US DOD MIL-STD 881A)
