results of the literature review of Change Readiness conceptualizations show that emotions, process orientation and time in change readiness approaches seem to have significant meaning regarding the successful completion of change projects. In this respect, affective and cognitive components may serve as antecedents of an overall evaluative judgment. These aspects have been neglected in previous theories as well as in empirical research. Thus, the empirical part of this dissertation attempts to narrow the empirical research gap by applying the multilevel framework of change readiness introduced by Rafferty, Jimmieson, and Armenakis (2013) and the process-based approach of change readiness suggested by Stevens (2013). Focus of the research is the cognitive and the affective aspects regarding the individual and the collective level over a given period of time in a change readiness context. The objective is oriented at the question whether the affective component of change readiness is a predictor of the potential outcomes positive and negative. Furthermore the potential and contriubutions of Neurocience research for Change Mangement will be analyzed and evaluated.
