Abstract : A series of diagrams depict the way automation has, historically, been introduced into existing organizations, emphasizing that automatic interchanges are the last to develop. The automation of air traffic control in the case of a flight path traversing adjacent control sectors is used as an example. The meaning of the total integration job is then developed in terms of levels of integration, hierarchical networks of systems, and organizational and functional interfaces by following down a systematic path through a series of diagrams through various levels to the 425L system. System specification documentation is developed with the aid of functional and physical configuration block diagrams of a typical L system as means of achieving integration. The requirement for continuous definition of interfaces, arising from the size, complexity and long lead times for modern systems, is brought out. Some implications both for and integration, in terms of top-level policy and interdependencies between systems, are discusse. The applicability of the discussion to both business systems and command and control systems is pointed out. (Author)
