The document is the first of a five-part series focusing in minute detail on the processes involved in the formulation of an instructional systems development (ISD) program for military interservice training that will adequately train individuals for a particular job. The Analyze phase consists of five steps, diagrammed by flow charts. The first step, Analyze Job, establishes what constitutes adequate on-the-job performance, focusing on what tasks, performed in what manner, under what conditions, in response to what cues, and to what standards, make up the job. The second step, Select Tasks/Functions, focuses on the selection of tasks that need training and those that do not in order to ensure some form of instruction for important tasks. The third step, Construct Job Performance Measures, provides measures to test whether individuals are performing their tasks. The fourth step, Analyze Existing Courses, presents procedures for reviewing the documentation of how existing courses were developed and validated and to determine whether the methods used are likely to have produced a course that will meet present training needs. The fifth step, Select Instructional Setting, focuses on providing adequate and appropriately timed training resources. A list of references, glossary, and index are included. (Author/EC)
