It is necessary to overcome the lack of precision in the meaning of the term ''information'' and the resulting lack of a method of developing an information requirement. This article proposes a generally applicable, prescriptive, and widely understood definition of management information. Based on Nadler's concept of system matrix, a Management Information Matrix is developed, composed of eight elements (function, inputs, outputs, process, environment, display media, human agents, and attention catalysts) and six dimensions (physical, time, value, control, interface and state). A regorous description of each cell of the prototype matrix is given. The effectiveness of the resulting framework in defining the information content of an M.I.S. output is evaluated. and a case study of its use is presented.
