This paper refers to the term ’implementation’ as the process of integrating a new technology into established workfows. Especially in health care this has proven to be a very critical phase and many large-scale projects have failed on this very last mile. Although strategies such as requirements engineering, co-designing and user interaction design have been proposed to reduce the risk of end-user rejection and subsequently project failur. There is still no tool to analyze, predict and quantify user acceptance and identify critical areas which might be addressed before the start of the implementation phase in order to reduce resistance and increase the effectiveness and effciency. © 2014 IEEE.
