"The term "systems engineering" is a term with an air of romance and of mystery. The romance and the mystery come from its use in the field of guided missiles, rockets, artificial satellites, and space flight. Much of the work being done in these areas is classified and hence much of it is not known to the general public or to this writer. But one term that has defied classification limits is the term "systems engineering." One sees the term "systems engineering" in technical help-wanted advertisements in newspapers and magazines. For example, the New York Times advertisements have often mentioned it, and it is far from rare in the advertising carried by the magazine Scientific American. The term is also found among the course offerings of a few leading universities."
