“…Roughly, different context transition strategies can be summarized with phases of 'unfreezing', 'moving', and 'refreezing', according to Krüger (1997), or 'planning', 'realization', and 'control', as described by Heusler (2004). The decision about which strategy to choose is also interrelated with the implementation object scope, whether a complete concept is planned to be implemented at once or in parts, and whether a 'perfect' solution is desired or a proximity solution (Engstler, 2009). Nevertheless, the strategy selection also serves to specify the implementation steps, their chronological order, capacity planning, and budgeting of the necessary resources (Daniel, 2001).…”
