Technology involves the organization and delivery of science for the presumed betterment of humankind. Management involves the interaction of the organization and the humans in the organization with the environment. Here we interpret environment in a very general sense to include the complete external milieu surrounding individuals and organizations. Hence systems engineering as a management technology involves three ingredients science organizations and their environments. Information and knowledge is ubiquitous throughout systems engineering and management efforts and is in reality a fourth ingredient. Systems engineering is thus seen to involve science organizations and humans environments technologies and information and knowledge. The process of systems engineering involves working with clients in order to assist them in the organization of information and knowledge to aid in judgment and choice of activities. These activities .
