Summary Directed by Military Streamline Program, the missions and organization of Navy shipyards were undergone a great change in recent years. They were transformed from a ships maintenance facility into a district-liked Logistics Support Command. It not only repairs ships, but also takes care of security measurement and utility management that were once operated by Naval District. During the process of transform and changes, the employees and servicemen of the shipyard are playing an important role in transferring skills and assignments. But the inevitable impact and effects also greatly affected these people on every aspect. There are rare academic studies that focused on Navy logistics service personnel, especially on relationship among ¡§work quality¡¨ and ¡§organizational commitment¡¨. Due to these two factors are useful criteria to evaluate the performance of the streamline program. A further study can help to ease the impact on both organization and its people. The core missions of Logistic Support Commands are ships maintenance and repair that was inherited from the shipyards. The work force is mainly comprised by technical sergeants and civilian employee. Technical sergeants can be replaced through recruiting system, but civilian employee are no longer hiring. The aging and declining of work force would increase the workload and stress on existing person. The situation also greatly affects the quality and competence of Navy ships¡¦ maintenance capability. This thesis is to examine the impact on civilian employee of Logistic Support Command during the streamline process. It focuses on the relationship and affection between ¡§work quality¡¨ and ¡§organizational commitment¡¨ during this specified period. It also can present as an indication for planning department on next stage of streamline. The purposes of this research are to uphold employee¡¦s work quality while organizational commitments decreasing, to implement streamline program properly, to promote work effectiveness, and to fulfill mission adequately. The object of this research is civilian employee of Navy Logistic Support Command. There were total of 182 survey have been delivered, and 177 effective feedbacks were received. The analytical methods are factors analysis, descriptive statistical analysis, correlation coefficient analysis, and regression analysis. The outcomes of this research are: 1. Every factors of streamline process should positively connect to ¡§work quality¡¨ and ¡§organizational commitment¡¨, but ¡§group relationship¡¨ does not. 2. Employee who has more conscious about work quality; such as content, condition, and lifestyle of work, is more likely to remain in the organization and committed to it. 3. ¡§Organizational streamline¡¨ and ¡§organizational commitment¡¨ are positively correlated. The suggestions of this research are: 1. Design streamline program appropriately, and emphasize communication repeatedly. 2. Simplified operation process, and focused on work quality. 3. Encourage employee to life-long learning, diversify his own skill. 4. Persuade senior employee to stay longer, pass their techniques to fresh hands, and strengthen organizational commitment as well.
