The growth of small-to-medium businesses can have a detrimental impact on the efficiency of the employees in executing internal business processes. In many cases, particularly in this scenario, technology was called upon to remedy the situation. Through a canonical action research project, we investigated and analysed the technology adoption and diffusion issues that the professional construction management team of a small-to-medium-sized construction company was experiencing. During this action research project, literature suggested technology adoption issues, were confirmed. In addition new issues were identified and analysed. By means of a conceptualized figure, the changes in the understanding and relationships among mobile computing adoption and diffusion issues, experienced in this construction company, were illustrated. This study concludes by providing a theoretical framework that illustrates the mobile computing adoption and diffusion issues, as well as an explanation of significant issues that should be considered in the endeavour of successful mobile computing adoption and diffusion within a small-to-medium-sized construction company, based in Gauteng, South Africa.
