Information system (IS) plans can vary in length and detail. One must, therefore, be able to tailor the existing planning methodologies to produce the desirable outputs. This article proposes a framework of demand-centric adaptive IS planning process and applies it to a case study that demonstrates how to adapt the methodology to produce an IS plan for a small commercial bank. Following the output-driven adaptive approach, the project was completed on time with expected quality. The project document provides the bank's management with guidelines for allocating their information resources to meet the current and future needs of business. # 2001 Elsevier Science B.V.
