Systems engineering has been recognized for over 60 years as essential to the proper development of complex and complicated man-made systems. It has been applied to a wide range of technological projects involving design, development, construction and maintenance. Examples are automobiles, urban infrastructure, environmental controls, aircraft, spacecraft, software, hardware, and ships. Systems engineering is the discipline that integrates complicated systems, ensures operability, balance and integration, and defines systems success. One example of a complex system that clearly displays the hallmarks of skilled systems engineering is that of planet Earth and its external support systems (the sun, our galaxy, our moon, etc.). It is beautifully designed, optimally positioned within the solar system, and intricately balanced to enable and sustain life. System Earth has all the tailor-made features researchers have determined are necessary for a planet to be capable of supporting living things.
