The Systems Engineering Process

Systems engineering relates primarily to the design and
development of systems with an emphasis on;
– transforming an operational need into a description of system
performance parameters.
– an iterative process of functional analysis, synthesis, optimization,
definition, design, test and evaluation
– ensuring that there is physical, functional, and program
compatibility between elements of the system
– integrating performance, producibility, reliability, maintainability,
manability, supportability, and other “-ilities” into a comprehensive
engineering effort


Systems engineering is not an engineering discipline per
se, but the amalgamation of many technical and nontechnical disciplines.
Systems engineering is “Designing for the Life Cycle”.
