Abstract : An information system is concerned with the communication of concepts and data about the system itself and its environment. Most of its time and energy is spent in designing itself as a system, not in communicating status information or orders for action. Information-processing jobs are arranged hierarchically, and for each job level, there is a corresponding level of aggregation of the concepts and data used for information processing. High-level information is filtered through many lower levels, each of which introduces some degree of noise or bias into the system. Communication occurs both up and down the job hierarchy: messages passed downward generally include concepts and data that determine system operation; messages passed upward are usually indications of how effectively the system is developing or operating. The use of computers in information systems tends to increase specialization around the lower-level jobs, and, consequently, system communication and integration may be inhibited. Therefore, the introduction of computers into information systems must always begin at the lowest level of aggregation in the job hierarchy. Only those information-processing jobs whose rules can be standardized precisely are suitable for automation. (Author)
