This paper examines empirical evidence of support by managers for form
al rational as opposed to ad hoc approaches to IT strategy. The eviden
ce was gathered by a large scale survey of IT managers in the UK priva
te and public sectors. A heuristic conceptual model was used to place
organizations on a continuum for several aspects of IT strategy. The a
uthors found that most organizations appeared to subscribe to formal r
ationalism, but only in some aspects of strategy.
