This study was a perceptual evaluation of the CONUS installation maintenance support structure by application of the contingency theory of management. Decentralized maintenance support was evaluated against centralized support to determine the most efficient and effective concept for organizational structuring at installations in CONUS. The study concluded that centralization was the appropriate structural concept. As a result, a conceptual model was devised for structuring installation maintenance organizations that provided for centralized support of NON-TOE activities and TOE units.
