This module is part of a set of management and supervisor training (MAST) materials developed by the Department of Energy for the Waste Isolation Division. Its stated purpose is to enable trainees to identify and use managerial control. The first section of the module is an introduction that includes a terminal objective and opening remarks intended to focus the trainees' attention on the subjects discussed in the module. Most other module sections begin with a list of enabling objectives. Many sections contain "critical incidents" or real-life occurrences at the Deaprtment of Energy's Waste Isolation Pilot Plant that relate to the section topic. Some illustrate effective management practices, and some illustrate ineffective ones. Each critical incident includes "lessons learned" information. Section topics are as follows: the meaning of control, effective and ineffective control, establishing a control system, measuring productivity, evaluating people, rewarding people, and control through progressive monitoring. A list of "smart moves" is included near the end of the module. Contains seven references and a practice test. Answers and feedback for the test are provided. (YLB)
