Following the Enterprise's globalization grows, we are going to focus on the performance of branch more. Choosing the performance index is very important today. Thus, this research is regarding the methodology of new measurement of performance in branch business and consist of DEA(Data envelop analysis) and ANP(Analytic network process). First, I find out weight values using ANP, then using it as criterion, I choose the main influential factors on branch's activities and production. Then I suggest DEA-2Stage methodology and conduct the analysis of actual proof on the public enterprise The DEA-2Stage methodology is for discrimination the activity's effectiveness and the production's efficiency. The DEA-2Stage in branch methodology can help guide the strategy's direction as well as can measure the performance. Also the result of ANP is from the paired comparison made by current personnel and professional so it can applicate the suggestion of the branch strategy in future. Based on the DEA result, it also give the benchmark branch model to the branch which has low effectiveness level.
