The basic similarities between educational technology and organizational development provide a powerful rationale for collaboration. The two disciplines are essentially in the same business, that of systematically changing human behavior. System theory and the system model appear to supply the language and the technology through which such efforts could be effected. The Command Action Planning System (CAPS) employed by the U. S. Navy at the Human Resource Management Center, San Diego was successful for two reasons. First, the entire approach was systematic in nature (i.e., environmental demands were identified, outputs specified, functions derived, resources identified, and the process then implemented and modified until performance was satisfactory). Second, the collaboration of educational technologists and organizational development specialists allowed a comprehensiveness of effort that would have otherwise been impossible. The collaboration appears to have been made possible by the cross-disciplinary aspects of system theory and the integrative capabilities of the system model. (Author/WCM)
