Value Rational Engineering
Shuichi Fukuda, Adviser to System Design and Management Research Institute of Keio University
Early in the 20th century, our world was small and closed with boundaries. And, there were no appreciable changes.
erefore, we could foresee the future. ese days, however, we could apply mathematical rationality and solve problems
without any diculty.
As our world began to expand rapidly and boundaries disappeared, the problem of bounded rationality emerged.
Engineers put forth tremendous eort to overcome this diculty and succeeded in expanding the bounds of mathematical
rationality, thereby establishing the “Controllable World.”
However, our world continues to expand. erefore such an approach can no longer be applied. We have no other
choice than “satiscing” (Herbert A. Simon’s word, Satisfy + Suce).
is expanding open world brought us frequent and extensive changes which are unpredictable and diversication and
personalization of customer expectations.To cope with these situations, we need diverse knowledge and experience. us, to
satisfy our customers, we need teamwork.
ese changes of environments and situations transformed the meaning of value. It used to mean excellent functions
and exact reproducibility. Now, it means how good and exible we can be to adapt to the situations. us, adaptability is the
value today.
Although these changes were big, and we needed to redene value, a greater shift in engineering is now emerging. e
Internet of ings (IoT) brought us the “Connected Society,” where things are connected. ings include not only products,
but also humans.
As changes are so frequent and extensive, only users know what is happening right now. us, the user in this Connected
Society needs to be a playing manager–he or she should manage to control the product-human team on the pitch.
Moreover, this Connected Society will bring us another big shift in engineering. Engineering in this framework will
become Social Networking, with engineering no longer developing individual products and managing team products.
e Internet works two ways between the sender and the receiver. Our engineering has ever been only one way. us,
how we establish a social networking framework for engineering is a big challenge facing us today. is will change our
engineering. Engineers are expected to develop not only products, but also to dream society.
is book discusses these issues and points out that New Horizons are emerging before us. It is hoped that this book
helps readers explore and establish their own New Worlds.
