Purpose – To provide a case study in the implementation of mobile technologies in an operations management environment, and viewed through a model for technology acceptance. Design/methodology/approach – This is an assessment of the technology acceptance model(TAM) through action research, a practical implementation based upon understandings developed in the TAM. Findings – Provides fresh data to further develop the TAM, shedding light on some of the factors expounded within TAM, and their relationships. Research limitations/implications – This is not the empirical research required to fully validate the TAM, but is useful in terms of investigating its various features within a detailed case study. It is also useful in terms of the project management implications for the implementation of new technologies. Practical implications – Useful for those looking at the practical implementation of mobile technologies in an operations environment, and highlights the role of technology acceptance in the project management process. Originality/value – This paper fulfils an important role in helping to validate the TAM developed by other researchers.
