Model-Based Systems Engineering

a system of which he or she is a component. Input of human components of systems is crucial to the design process for generating requirements, but rarely for designing systems. • Private and public foundations issue grants to support “applied” research that neither science nor society knows how to “apply.” There is certainly a place for pure science, but much research should be done within the context of an overall system design so that when the research is finished society and science know where it will fit and can be used. • Systems are designed and built to solve overly simplified problems and thus create more problems than they solve. • Systems are designed and built to solve problems, and society then finds that the system proponents cannot prove that they have accomplished anything! This seems to be especially true for social systems. • Acquisition of large-scale, complex systems seems typically to involve huge cost and schedule overruns and disastrous performance shortfalls. How can these methodological errors be
