A cross-border remittance process was selected by a Taiwanese bank to pilot the test application of statistical process control (SPC). The results support the conclusion that the theoretical model developed in the last century is also applicable in financial institutions. The main interest of this research is to follow the success of the pilot case with three more work processes of the bank replicated SPC to further test its feasibility. The case of branch service counter processing, described in this article, proves that the adoption of SPC would easily detect special causes and common causes. Importantly, solutions would be easily generated based on the results of measuring process stability and capability. The case studies in this research reiterate that SPC is a powerful tool to improve a bank’s operation performance.
