Their model considers three main elements: entrepreneurial vision, organisational structure and behaviour, all of which influence and complement each other.[25] The authors claim that these factors have to be adapted at three levels: at the organisational level, at the level of top-managers and at the level of other employees. It means that an effective CE strategy cannot be dictated by top-managers, only instigated by them. In doing so, they have to create CE strategy from interactions between entrepreneurial vision, pro-entrepreneurial architecture and entrepreneurial behaviour.
