Abstract
Research on the relationship between computers and organization structure has mainly focused on the probable impact of technology on features of structure, while the effects of structure on technology have been relatively little considered apart from the way ‘organizationally invalid’ systems cause conflict and resistance. In recent processual perspectives, the relationship between technology and organization is seen not as deterministic but as one of mutual influence, with the outcome both for the organization and the technology emerging from interaction among various stakeholders during system development and implementation. This article, using a longitudinal case study, shows how organization structures can impact on the development process so as to alter computer‐based systems to a design which is unintended but more consistent with existing organizational arrangements. It also discusses how systems specialists and managers can assess organizational invalidity, and offers a contingent framework for the courses of action to be taken if invalidity occurs.
