In analyzing the managerial decisions at the central office of the Dufferin (Ontario) county board of education, this project sought to obtain the data needed to design an integrated management information system. A major component of the study was identifying users and their information needs and relating information to three different levels of decision-making: operational control, management (tactical) control, and strategic planning. Intensive interviews with board officials, superintendents, and elementary and secondary principals, along with the compilation of lists of major decision functions, provided the data for the study, which includes analyses of both board- and school-level decision-making. Among the results of the study were a systems analysis of the board's activities, an integrated, comprehensive list of functions and specific areas of decision-making, and the identification of information channels that contribute to decisions at the central office. Appended are lists of joint and individual decision functions of board members and principals, their information needs, and flow charts. (Author/WD)
