Ready access to accurate and timely information for decision making is a paramount requirement for public sector managers to function effectively in a political environment where fiscal management comes under close scrutiny. This paper presents a methodology for use in developing an integrated network of systems to support the information requirements for economic management. Of particular importance is the concept of developing an information systems architecture that provides an overview of the systems network required to support fiscal management. The proposed architecture identifies the major component modules and the information linkages between these modules. This information architecture can also serve as a road map for systems implementation.
