The second in a series of four reports on the Electronic Equipment Maintenance Training (EEMT) project, this document summarizes the system definition phase of the EEMT program. The purpose of this phase of the project was to define a comprehensive set of functions and training requirements that the EEMT must satisfy within the training mission of the electronics technician (ET) and electronics warfare technician (EW) schools, and define EEMT hardware requirements to support a prototype production effort. The procedures were to: (1) analyze a sample of ET and EW equipment to identify components and modules common to both ratings, (2) generate a list of tasks with terminal and enabling objectives and generalities derived for each task, (3) choose appropriate instructional objectives based on design boundaries, (4) develop five conceptual designs for the prototype EEMT, and (5) select one design for prototype development. Results were that inputs for the Device Test and Evaluation Master Plan (DTEMP) for two-dimensional and three-dimensional versions of the EEMT were developed to serve as the single management document for all test and evaluation efforts conducted during EEMT systems acquisition.
