“The pressure to generate the ideas and methods attributed to Systems Engineering stems directly from the needs of 20th century society. As our frontiers have disappeared, man has turned to technology to furnish the "good life" in a rapidly shrinking, crowded world. Our interdependence upon one another has increased in direct proportion to the population increase. The race to maintain or improve the operating efficiency of society has required that the systems and mechanisms that serve the society also become increasingly complex and interdependent.
Goode and Machal have provided statistics to illustrate the above. They note that the world population increased from 800 million in 1750, to 1200 million in 1850, and 2400 million in 1950. Maximum transportation speeds went from 40 mph in 1850, and 100 mph in 1900, to commercial transport speed of 350 mph in 1950 and supersonic transport planes of over 1200 mph in the 1960's. Our communication systems are a good indication of increasing complexity. U. S. telephones jumped from 350,000 in 1900, to 55 million in 1955.”

“It is hard to say whether increasing complexity is the cause or the effect of man's effort to cope with his expanding environment. In either case a central feature of the trend has been the development of large and very complex systems which tie together modern society. These systems include abstract or non-physical systems, such as government and the economic system. They also include large physical systems like pipe line and power distribution systems, transportation and electrical communication systems. The growth of these systems has increased the need not only for over-all planning, but also for long-range development of the systems. This need has induced increased interest in the methods by which efficient planning and design can be accomplished in complex situations where no one scientific discipline can account for all the factors. Two similar disciplines which emerged about the time of World War II to cope with these problems are called systems engineering and operations research.”

“Our future is dependent upon increasing cooperation and interdependence in a world tied ever more closely together by technologies of communications and travel.”

Context: Our future is dependent upon increasing cooperation and interdependence in a world tied ever more closely together by technologies of communications and travel. The emergence of a truly global civilization has been accompanied by the recognition of truly global challenges that require global responses that, as often as not, can only be led by the United States — and only if the United States restores and maintains its moral authority to lead.

“In a world in which training and functions of individuals and groups are growing more and more specialized the number of ways to accomplish any particular result increasing. Different design, different facilities, different equipment, different methods, and different organizational means are available to meet the needs of man. It is highly desirable that we have trained persons look at these varied possibilities to compare their effectiveness, and to point the way to sound engineering decisions. Systems Engineering Methods is directed towards the development of a broad systems engineering approach to help such people improve their decision-making capability. Although the emphasis is on engineering, the systems approach can also has validity for many other areas in which emphasis may be social, economic, or political.”

“As was rightly pointed out by Karl Polanyi in the 1940s, the 19th century laissez-faire regime can be thought of as one in which society is forced to conform to the needs of the market mechanism. "Instead of the economy being embedded in social relations, social relations are embedded in the economic system" in this laissez-faire regime. However, it was precisely because of this that the system gradually disintegrated from the early 20th century into economic and social chaos. "Since society was made to conform to the needs of the market mechanism, imperfections in the functioning of that mechanism created cumulative strains on the body social."”

“Societies grow into systems. The systems require management and are therefore increasingly wielded, like a tool or a weapon, by those who have power. The rest of the population is still needed to do specific things. But the citizens are not needed to contribute to the form or direction of the society. The more "advanced" the civilization, the more irrelevant the citizen becomes.”

“A new concept and a new method were needed. The concept from the engineering standpoint is the evolution of the engineering scientist, i. e., the scientific generalist who maintains a broad outlook. The method is that of the team approach. On large-scale-system problems, teams of scientists and engineers, generalists as well as specialists, exert their joint efforts to find a solution and physically realize it.
We are led to the concept of the system-design team, a small group of engineers or scientists, to lead a large project and organize the system effort. Such men have been variously called engineering scientists, system engineers, system analysts, or large-scale-system designers. The technique has been variously called the systems approach or the team development method. It is toward this man and his teammates that these discussions are directed. With the realization that not enough can be learned in all the required fields to make him a specialist, enough is introduced to make him aware of the language and problems of the specialist. This generalist is a new quantity in the engineering world, and his education must be begun.”

“Our well-founded claim, grounded on continuity, has greatly strengthened, during the same period, by the rapid advance of our population toward the territory — its great increase, especially in the valley of the Mississippi — as well as the greatly increased facility of passing to the territory by more accessible routes, and the far stronger and rapidly-swelling tide of population that has recently commenced flowing into it.”

“In the course of life, all such systems (i. e., the different evolutionary ridges) are somewhat functionally interdependent, as are components within each system (i. e., the different programs, schema, modules). Nevertheless, each system and system component has a somewhat distinct evolutionary history and time line. There is no single origin of religion, nor any necessary and sufficient set of functions that religion serves. Rather, there is a family of evolutionary-compatible functions that all societies more or less realize but that no one society need realize in full.”

“[In the year 1957] I have just returned from an exciting meeting of the American Society for Engineering Education where I heard a paper on the new discipline of systems engineering. It is no longer sufficient for engineers merely to design boxes such as computers with the expectation that they would become components of larger, more complex systems. That is wasteful because frequently the box component is a bad fit in the system and has to be redesigned or worse, can lead to system failure. We must learn how to design large-scale, complex systems from the top down so that the specification for each component is derivable from the requirements for the overall system. We must also take a much larger view of systems. We must design the man-machine interfaces and even the system-society interfaces. Systems engineers must be trained for the design of large-scale, complex, man-machine-social systems.”
