Successful organizational change experience can be easily copied by another organization in the same culture. Residence Administration (R.A.) in Taiwan had a wonderful change experience that can be learned by another public organizations in Taiwan. This paper used Sastry¡¦s(1997) organizational change theory and dynamic feedback loops to research the R.A.¡¦ successful change stories and compare with one health organization for deeper understanding. We know successful change is a dynamic structure, and found some helpful strategies for successful public organizational change: 1. Organizational performance was being influenced by two loops, strategy appropriateness loop and competence establishment loop. 2. Strategy appropriateness loop shows that frequently changing organizational main strategies would lead to bad organizational performance. 3. Competence establisyhment loop shows that there must be enough time to establish new competence for performing new strategies. 4. Change ability loop shows that higher organizational inertia led to lower organizational ability to adapt to its environment. 5. Inertia created loop shows that organizational inertia is highly related to its socialized process. According to the dynamic feedback loops, one organization could figure out its present situation and think its change strategies. This paper showed that Sastry¡¦s theory could explain the R.A.¡¦s change strategies well. Other public organizations can use R.A.¡¦s experience to make their own successful change stories.
