This paper assesses a performance evaluation framework for wealth management (WM) banks. We propose a method that combines the analytic hierarchy process (AHP) with the assurance region (AR) model of data envelopment analysis (DEA) to enable a consensus decision. We also present several strategies for using this methodology, such as Delphi procedures. The analysis results indicate that evaluators (evaluation members) responsible for recommending the business performance of WM banks in Taiwan employ the AHP and DEA methods. In this study, we summarize the evaluation analysis process followed by the evaluators, emphasizing the methodological aspects.
