Abstract

This research explored IT governance framework adoption, leveraging established IS theories. It applied both the technology acceptance model (TAM) and the technology, organization, environment (TOE) models. The study consisted of developing a model utilizing TOE and TAM, deriving relevant hypotheses. Interviews with a group of practitioners piloted a four-page Web-based survey, which was then deployed to large groups via social media and email.

Statistical analysis approaches included SPSS, Excel, and the primary tool SmartPLS, which leverages the second generation statistical approaches of structural equation modeling - partial least squares (SEM-PLS). This path modeling technique measured the relationships between the independent and dependent latent variables of the research model.

The results illustrated the strength of the model. The relevance of the core TAM model was validated. Hypotheses pertaining to the impact of perceived usefulness on intent were strongly supported. The aspect of ease of use was also supported. Hence, TAM was confirmed as an appropriate theory to provide insight into the adoption of IT governance frameworks. The study also found that organizational norms and support had a significant relationship with intent to adopt. The hypotheses that TOE factors influenced adoption were not strongly supported in this study. These aspects may nevertheless prove more material in a broader and less homogenous population.

The other finding was that organizations had implemented tailored frameworks, not a single standard framework. The majority had established governance in some areas, although not throughout, while very few indicated that there was none in place.
