An integrated approach toward strategic information systems planning Pages 373-394

Within the competitive global environment, information has become a key resource for increasing a corporationʹs competitiveness by changing the nature or conduct of business. Accordingly, corporations are now seeking a method for information systems planning to maximize their strategic effectiveness. Strategic Information Systems Planning (SISP) refers to the process of creating a portfolio for the implementation and use of IS to maximize the effectiveness and efficiency of a corporation, so that it can achieve its objectives. An investigation of SISP, however, showed that only 24% of planned applications were actually developed (Int. J. Comput. Appl. Technol., 8 (1995), 61; MIS Quarterly, September (1988), 445). This figure clearly shows that enhancements are required for current SISP processes. In particular, this paper focuses on SISP methodologies, which provide support for overall SISP processes. The paper initially identifies four general SISP methodology problems: lack of support for Information Technology Architecture, under-emphasis on information technology opportunities, duration of SISP, and lack of support for business process reengineering. Next, it proposes an integrated SISP methodology which solves the above problems while retaining the advantageous qualities of current SISP methodologies. Finally, a case study is added to show how the methodology actually works in practice.
