Most of the published materials referred to in this paper concern environmental rather than additudinal variables, reflecting a generalized preoccupation with systems, rather than deliverers. The expectation usually is that improved delivery of services will occur when more efficient mechanisms are found which bring potential clients and waiting services into a more functional relationship. Essentially, these new mechanisms are expected to achieve the following: 1) Expedite the process through which clients get to services and services get to clients; 2) Serve more clients more successfully at a reasonable social and economic cost; 3) Perform the task with the available professional and nonprofessional manpower resources; 4) Enhance client motivation and self-regard in the course of delivering the service; 5) Provide ample opportunities for client choice and decision making in the delivery process; 6) Protect potential clients, insofar as possible, from deterrent biases, caprices, and personal ideologies of those who serve them; and 7) Eliminate client deprivation resulting from worker apathy, inefficiency, and unprofessionalism. Preliminary to discussing systems, it may be helpful to examine some current rehabilitation service delivery problems that confront the field.
