Over the past few decades, information technology (IT) has played a central role in transforming society and enabling the knowledge economy. Such transformation has also introduced new problems, leading to a growing need among organisations to adopt IT governance frameworks in order to provide assurance that their IT operations meet required standards and community expectations. However, the adoption of such frameworks is a complex phenomenon fraught with risks and challenges, and is yet to attract adequate research attention. This study explores factors influencing the success of IT governance frameworks adoption by proposing an integrated research model that draws upon the technology-organisation-environment (TOE) framework and the Delone and McLean’s information systems (IS) success model. Data were collected from 126 Australian organisations that have adopted IT governance frameworks through mail surveys and analysed using the partial least-squares (PLS) method. The findings demonstrate that ease of use, innovation compatibility, training and external pressures were significant to the success of IT governance frameworks adoption, assessed through user satisfaction; while ease of use, top management support, external support and user satisfaction were found significant to organisational performance. These findings are of relevance to researchers, practitioners and a broad range of organisational stakeholders, given the growing global importance and implications of IT governance frameworks adoption to organisations.
