This study applies the Delphi method to design services with convergence characteristics in the financial sector. In designing a service robot for practical deployment that can support and replace bank teller, the opinions and judgments of various expert groups were extracted and a consensus process was made through feedback. A total of six dimensions and thirty service elements were derived over three rounds. Coefficient of Variation and content validity were used to verify the suitability and reliability of the selected service elements. As a result, the essential service element of robots was interaction with customers, followed by basic and professional financial services. Based on these service factors, we proposed two types of service models. support mode to assist employees during business hours and alternative mode on behalf of employees outside business hours. It is hoped that this study will use the Delphi technique in the design of IT convergence services.

A Kano model was used to classify the quality attributes of the service robot function for actual deployment that can support and replace bank employees. Quality attributes for a total of 6 dimensions and 23 service elements were divided into bank employees and customer groups, and service priorities were derived after comparative analysis. The Decision tree model was used to supplement the excessive simplification of quality attributes by the modest number of Kano models and to classify and predict by segment market. Of the 23 services, 16 were classified into the same attributes in both groups. 6 services classified as combination attributes used a Decision tree to identify differences in perception of quality attributes among groups. In terms of basic financial services and professional financial services, it was confirmed that bank employees feel financial service robots more attractive than ordinary customers. In the design of IT convergence service, we propose a methodology for deriving quality attributes by combining a Kano model for classifying quality attributes of two groups and a Decision tree for forecasting subdivision markets.

Nowadays data-based decision making is emerging as the center of the business environment paradigm, but many companies do not have data-driven decision-making systems. It has also been studied that using an expert’s intuition in decision making can be more efficient in terms of speed and cost, compared to analytical decision making. The goal of this study is to analyze customer churn factors using a group of experts within a financial company from the viewpoint of decision-making efficiency. We applied a debit card ‘A’, product of the National Credit Union Federation of Korea. The churn factors of all the financial expert groups were examined. Also. the difference in each group (management support, card recruitment, customer service group) was analyzed. We expect that this study will be helpful in the practical aspects of managers whose environments is lack data-oriented infrastructure and culture.
