“Models are used essentially for evaluation and prediction purposes as well as for the analysis and study of the different parts of the system so that the systems engineer or designer may arrive at sound engineering decisions regarding the system design.”

“In the minds of many writers systems engineering is synonomous with component selection and interface design; that is, the systems engineer does not design hardware but decides what types of existing hardware shall be coupled and how they shall be coupled. Complete agreement that this function is the essence of systems engineering will not be found here, for, besides the very important function of systems engineering in systems analysis, there is the role played by systems engineering in providing boundary conditions for hardware design.”

“Within the past ten years there have appeared with increasing frequency books, articles, conferences, and monograms dealing with system engineering, system analysis, system design, the systems approach, the design of systems, system theory, and problems of systems engineering. The number of publications and the stature of their authors does not allow the dismissal of the subject as a passing fad. The breadth of engineering activity involved in even a cursory examination of recent publications is of interest… It is therefore obvious that whatever Systems Engineering may or may not be, it is non-sectarian and encompasses activities that are of concern in all phases of engineering. On the other hand undergraduate college offerings akin to Systems Engineering are rather limited and even graduate programs are not extensive.”

“Designed as a companion volume to the acclaimed Object-Oriented Analysis, this book focuses on the middle part of the software lifecycle: the activity of design. It shows readers how to apply object-oriented design, and how to tailor and expand the method to suit specific organization and project needs. Readers will explore the major issues in OOD; the role of OOD in the systems lifecycle; how to use graphical notation; strategies for creating design; and hints for evaluating the efficiency of a design created with OOD. For software engineers and other users undertaking real-world systems development projects and designing overall software architecture for systems will find this reference approach to improving systems design indispensable.”

“The purpose of "Engineering Cybernetics" is then to study those parts of the broad science of cybernetics which have direct engineering applications in designing controlled or guided systems. It certainly includes such topics usually treated in books on servomechanisms. But a wider range of topics is only one difference between engineering cybernetics and servomechanisms engineering. A deeper - and thus more important - difference lies in the fact that engineering cybernetics is an engineering science, while servomechanisms engineering is an engineering practice.”

“This report summarizes the activities of the M. I. T. Computer-Aided Design (CAD) Project from 1 December 1959 through 3 May 1967 in the development of a generalized 'system of software systems' for generating specialized problem-solving systems using high-level language techniques and advanced computer graphics. Known as the AED Approach (for Automated Engineering Design) the Project results are applicable not only to mechanical design, as an extension of earlier development of the APT System for numerical control, but to arbitrary scientific, engineering, management, and production systems as well.”

“Enterprise engineering is an emerging discipline that studies enterprises from an engineering perspective. The first paradigm of this discipline is that enterprises are purposefully designed and implemented systems. Consequently, they can be re-designed and re-implemented if there is a need for change. The second paradigm of enterprise engineering is that enterprises are social systems. This means that the system elements are social individuals, and that the essence of an enterprise's operation lies in the entering into and complying with commitments between these social individuals.”

“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.”

“[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.”

“With the subsequent strong support from cybernetics, the concepts of systems thinking and systems theory became integral parts of the established scientific language, and led to numerous new methodologies and applications -- systems engineering, systems analysis, systems dynamics, and so on.”
