In this paper we explore the interplay between organisational identity and information systems (IS). More specifically, we examine how the appropriation of new IS may influence established patterns of identity enactment and inter-organisational practices. We report on findings from three in-depth case studies that depict the adoption and use of a new collaborative 3D modelling technology by a metal fabrication firm in the architecture, engineering, and construction (AEC) industry. We investigate the manner in which the new technology was associated with changes in the company’s practices, interactions, and organisational identity. Our study contributes to the scarce research on IS and organisational identity by emphasising the relational, practical, and dynamic nature of organisational identity.
