A combined methodology for information systems analysis and design based on ISAC and NIAM

Abstract A Combined Methodology for information systems analysis and design is presented. The basis of the methodology is a hybrid of two existing methodologies, ISAC and NIAM. The business analysis and information analysis of ISAC are combined with the conceptualization process of NIAM, and thus the stronger parts of each methodology are combined to form a more inclusive, applicable methodology, while the weaker parts of the original methodologies are discarded.
