There is a shortage of evidence based research that provides organizations with the necessary information in support of their technology adoption decisions in relation to ITSM technologies. As such, this research study attempted to bridge the gap by offering insight on possible factors that could influence such decisions. An examination of relevant literature contributed to the foundation and development of the research questions, hypotheses, and assessed factors for this research effort. The study extended the predictors of Davis' (1989) TAM, perceived usefulness (PU), perceived ease of use (PEOU), to include the variables need, cost-effectiveness, and reliability as possible factors influencing IT decision-makers to adopt the information technology infrastructure library (ITIL), utilizing a quantitative research approach. The results showed that statistically significant relationships exist across the assessed factors, contributing to overall adoption decision. The implications of the study are that decision-makers faced with new technology adoption challenges have insight on possible factors that could impact their decision in addition to assessing how the technology fits within the existing organizational culture, mission, structure, and long term strategic goals.
