Abstract: A method and structure for selecting from a plurality of communication arrangements is performed by inputting a first party's ability to communicate with a second party. The invention evaluates the communication arrangement based on the first party's ability to communicate and repeats the evaluating process for a different communication arrangement if the first party's ability does not match a communication arrangement previously evaluated. The invention performs a cost-benefit analysis with respect to a communication arrangement matching the first party's ability and implements a communication arrangement when the first party's ability matches a communication arrangement. The cost-benefit shows whether the communication arrangement is justified.
