This executive summary describes the communication/language objectives-based system (C/LOBS) developed to support the front-end analysis efforts of the Defense Language Institute Foreign Language Center. The C/LOBS functions as a subsystem of the instructional systems development (ISD) approach currently in use in the TRADOC school system. The task assigned to this project, which is described in 13 volumes, was to develop a systematic set of procedures for determining terminal skill objectives (TSOs) and their supporting enabling objectives (EOs) for foreign language training within the ISD framework. This system must be capable of determining the TSOs and EOs for any job/duty position in any language. Five job/duty positions and three languages were selected for field testing and system validation. The languages are Iberian Spanish, Russian, and Mandarin Chinese; the five job/duty positions are: 11B infantryman, special forces (Russian); 11BF1 operations/intelligence specialist, special forces (Chinese); 91B medical specialist, special forces (Russian); 05B radio specialist, special forces (Russian); and military advisory and assistance group officers, Air Force (Spanish). Three phases were developed for the C/LOBS: (1) the task analysis phase; (2) the TSO conversion phase; and (3) the EO phase. (SW)
