Over the past few decades, the potential of information systems (IS) to support organizational activities and help them gain competitive advantage has been widely recognized. At the level of strategy, there is a genre of organizational activities dedicated to realizing this potential. Methods known broadly as strategic information planning have been constructed to support such activities in organizations but these methods have not lived up their promises. Meanwhile, the use of evolutionary approaches in the application of IS in organizations have also received some attention. This paper describes and analyzes a case study of the evolution of the IS strategy within LeaseHold NV, a Dutch global leasing company. The study reveals that no IS planning was used. Instead, concepts of organizational evolution are found to be useful in analyzing the development of the IS strategy at LeaseHold. © 2002 Elsevier Science Ltd. All rights reserved.
