This paper sets out to question established practice in the design and
implementation of information systems. It focuses on the systems deve
lopment process and the interactions that take! place between the vari
ous groups involved in that process. It will be argued that systems de
velopment activities are interest-based in nature to the extent that a
n 'unholy alliance' is struck between the interested parties. The usua
l methods applied to (medium-to large-scale) systems development are f
ormalised and mechanistic and tend to ignore the wider social and orga
nisational issues involved. This bias and partialness often results in
dysfunctional outcomes which have negative consequences for those usi
ng the systems and their organisations. The dysfunctional effects are
explored through a consideration of three recently considered case stu
dies. The authors identify a form of technical subterfuge whereby tech
nical experts, in an attempt to compensate for their own lack of chang
e management expertise, project a false image of their knowledge and i
ts representativeness of the wider context. We have referred to this p
henomenon as 'virtual know-how'. The paper concludes by suggesting tha
t creation of a change management space, that moves beyond merely tech
nical issues, is a necessary but badly neglected element of systems de
velopment practice. (C) 1998 Published by Elsevier Science Ltd. All ri
