A case study tested the premise that people cope with ambiguity in particular ways within an organizational context, negotiating for understanding and choice through the manipulation of power, ideology, and technology. The study focused on the implementation of a satellite communications network in local Catholic Church offices and on staff members' positive and negative perceptions of ambiguity that resulted from the new system. Results showed that ambiguity was reduced within the offices through the use of power, ideology, and technology. From an external perspective, ambiguity was used in a positive way to open up possibilities for the creative use of technology, for renegotiating the goals of the Catholic Communications Network, and for realigning the power structure of the communication system of the Church.
