This paper is a discussion on the problem of establishing information requirements in changing and ongoing business organisations. Attempts within existing software development paradigms to cope with business change are identified and discussed, and their problems concerning business change are highlighted. The alternative spiral of change model of tailorable information systems is proposed for thinking about establishing changing and ongoing information systems requirements. It is also proposed that information should be reconceptualised as tailorable. Such a reconceptualisation would allow us to explore ways of establishing information systems requirements that cope with business change. Deferred system’s design is proposed as a form of business software design and development that can cope with business change, as well as with the contextual and situational nature of tailorable information.
