Until recently, a mining companys data resided in the department that was responsible for that information. Property data were on the computers in land administration, hydrocarbon data were in the well administration group, maps were found in the map department and so on. The executive team concluded that this arrangement was dysfunctional, so the CEO announced that all information would be placed on a central server system so it is widely accessible. If someone needs a colour map, for example, he or she can retrieve it from the central server without going through the map department. Rather than welcome the change, employees in several departments complained, offering several arguments why other groups should not have direct access to their data files. Some departments tried to opt out of the centralised server system. Using the model of sources and contingencies of power, explain why some groups opposed the central server model of data access. This incident actually occurred in a resources company and was a major challenge for those implementing the change. Students should answer this question by breaking it down into the power sources and contingencies.
