Supervision is the application of knowledge, attitudes, and skills through human interaction to provide direction, support, or feedback. Supervision occurs in a specific situation, and, therefore, analysis of the situation may determine the skills and behaviors appropriate to that situation. Supervision is not accomplished through the application of a set of general supervisory behaviors, nor through the utilization of certain social processes to the exclusion of others. If sound theories of supervision are to be developed, specific supervisory situations should be examined and then generalized to logically fit all supervisory situations. Communication and human relations are the two most important elements in a model that was conceived to aid decision making. Use of the model forces the collection of data and the determination of needs in specific supervisory situations. (JD)
