[+] Transform
an operational need into a description of system performance
parameters and a system configuration through the use of an
iterative process of definition, synthesis, analysis, design,
test, and evaluation.
[+] Integrate
related technical parameters and ensure compatibility of all
physical, functional, and program interfaces in a manner that
optimizes the total system definition and design.
[+] Integrate
reliability, maintainability, safety, survivability, human
engineering, and other such factors into the total engineering
/ production effort to meet cost, schedule, supportability,
and technical performance objectives.
