"“The term is being applied to the creation of new systems by bringing together existing operational systems under a single umbrella and, presumably, creating or adapting links and interactions between the operational systems, which become subsystems of the higher level umbrella system.”"

“The world about us can be looked at in a variety of ways. One way is to see the world as made up from many interacting systems: weather, societal, economic, ecological, floral, faunal, tectonic plate, oceanic, and so on. This is very much a connected view of the world: nothing is isolated and totally independent; everything is part of something bigger, and everything comprises many interacting parts — subsystems.”

“The real world is made from open, interacting systems, behaving chaotically.”

“Soft systems viewpoints are those held by behavioural, management, social anthropology, social psychology and other science students concerned with observing the living world, and in particular the human world. Human activity systems are messy, in that they do not exhibit a clear need or purpose - if they can be said to exhibit purpose at all. Indeed, so complex is the real world of people that the idea of driving towards optimal solutions may be a non-starter - perhaps we should see if we can simply understand and concern ourselves with improving the situation.”

“System engineering is the art and science of creating effective systems, using whole system, whole life principles.”

“The Holy Grail of systems engineering, a generic systems methodology has been the subject of the author’s ongoing research for over 20 years.”

“There seem to be two fundamental schisms in thinking: the hard/soft and the open/closed.”
