Businessdictionary online, viewed Aug. 31, 2018 (Systems analysis: In a broad sense, a general methodology (not a fixed set of techniques) that applies a 'systems' or' holistic' perspective by taking all aspects of the situation into account, and by concentrating on the interactions between its different elements. It provides a framework in which judgments of the experts in different fields can be combined to determine what must be done, and what is the best way to accomplish it in light of current and future needs. Although closely associated with data or information processing, the practice of SA has been in existence since long before computers were invented)
