Abstract/Summary The thesis “Acceptance and use of the Service Oriented Computing paradigm: the IT professionals’ perspective” focuses on the question: what are the critical factors that influence IT professionals’ intentions to accept and use the Service Oriented Computing (SOC) approach to systems development? This work considers IT professionals as the key stakeholders in the SOC acceptance and use process and argues that the acceptance and practical use of SOC depends – at an early acceptance stage – primarily on the individual-level acceptance decisions made by senior IT professionals working for an organisation. Consequently, SOC acceptance and use (in its early stage) is seen as a bottom-up process driven, and to a high degree controlled, by the “early adopters” (Rogers 1995) of this technological paradigm (i.e. involved senior IT professionals). Although SOC is considered the enabling technological approach in many different future areas (e.g. eBusiness, eGovernment, eScience etc.), very little research exists on the process of practical acceptance of this paradigm, in particular focusing on the perspective of the “early stage” key stakeholders of this acceptance process, namely the IT professionals. This thesis consists of four major parts. First, it reviews existing literature on technology acceptance and use and confirms the absence of an established theoretical framework in the domain of individual-level technology acceptance in the IT industry. Second, based on data collected in a series of exploratory interviews with senior IT practitioners, an initial model explaining the acceptance and use of SOC among IT professionals is being proposed. Third, the derived model is revised and reformulated using an eGovernment case study. And forth, based on the refined model, a survey instrument is developed, pilot-tested and administered to senior IT professionals currently using the SOC approach to systems development in their professional work. This thesis makes a contribution to IS research in several ways. While there exists extensive, well-grounded and well-accepted research in the domain of “IT end-user” individual-level technology acceptance, the research on technology acceptance in the IT industry (i.e. technology acceptance by the IT professionals) is very limited, and nearly all studies carried out in this IS research field are concerned with established approaches or technologies. The current study is among the few examining the perspective of “early adopters” or “innovators” (Rogers 1995) instead of investigating the acceptance process of “early majority” or even “late majority”. Moreover, to the author’s knowledge it is the first study examining the process of individual-level SOC acceptance with a particular focus on the perspective of the “early stage” key stakeholders of this acceptance process, namely the IT professionals. One of the additional strengths of the study is the usage of multiple research methodologies – exploratory open-ended interviews, qualitative case study and web-based survey. This research is expected to be very interesting to researchers focusing on technology acceptance in general and on technology acceptance in the IT industry in particular. This research might also be of interest to IT practitioners considering to accept and use the SOC approach in their future applications.
