Principles of Information Systems Analysis and Design

This book represents an entirely new approach to information systems development and its teaching. The authors have distilled successful theories of software engineering and business proceesses into a simple logical methodology which involves the use of three fundamental structures. It is shown how these structures, called black box, state machine, and clear box, can be used to form comprehensive and rigurous hierarchical descriptions of any business information process or information system. Of special interest ot those who are teacing or studying information systems development, this new work will also be of particular importance to those who are actively involved in business processes supported by information systems.
