Organizations introduce changes to adapt themselves to the extremely changing context. These changes often impact business and information technology (IT) domains. In most of the cases, the scope of the organizational elements in these domains requiring adaptation is not well defined, leaving out elements, what can lead to misalignment. Thus, it is important to know the impact scope in order to perform a full adaptation. When reviewing the literature in the business–IT alignment field, we found that there are no works dealing with this aspect. To fulfill this lack, we carry out a systematic review of change management works and find out a set of clues. We apply them to the business–IT alignment field and as a result propose a change management metamodel, a set of rules and an algorithm to forecast impact scope and adaptations. To operationalize our contributions, we propose a software and demonstrate its applicability through a case study.
