Identifying subsystems in information systems analysis

摘要

The paper discusses five main criteria for the construction of subsystems of an information system. The criteria are flexibility/changeability, separability, comprehensibility, integrability and data usage and/or creation. Two procedures based on the data usage and/or creation criterion are described. These procedures are used to determine the composition of each subsystem, keeping the other four criteria in focus. An application of the methodology to a sample data is presented.
