Loan consultants assist clients with loan application processing and loan decisions. Their duties may include contacting people to ask if they want a loan, meeting with loan applicants and explaining different loan options. We studied the efficiency of service quality of loan consultants contracted to a bank in Korea. They do not work as a team, but do work independently. Since he/she is not an employee of the bank, the consultant is paid solely in proportion to how much he/she sell loans. In this study, a consultant is considered as a decision making unit (DMU) in the DEA (Data Envelopment Analysis) model. We use a principal component analysis-data envelopment analysis (PCA-DEA) model integrated with Shannon's Entropy to evaluate quality efficiency of the consultants. We adopt a three-stage process to calculate the efficiency of service quality of the consultants. In the first stage, we use PCA to obtain 6 synthetic indicators, including 4 input indicators and 2 output indicators, from survey results in which questionnaire items are constructed on the basis of SERVQUAL model. In the second stage, 3 DEA models allowing negative values are used to calculate the relative efficiency of each DMU. In the third stage, the weight of each result is calculated on the basis of Shannon's Entropy theory, and then we generate a comprehensive efficiency score using it. An example illustrates the proposed process of evaluating the relative quality efficiency of the loan consultants and how to use the efficiency to improve the service quality of the consultants.

Recently, due to external environment like the changes in health policy and various healthcare accreditations, along with hospital's internal efforts to improve the quality of medical services, demands for the development of medical information systems are increasing. Some examples are clinical information like DUR (Drug Utilization Review), CVR (Critical Value Report), and automatic benefit processing by treatment purposes, or hospital DSS (Decision Support System) on overall medical practice. Such systems act as a guide in making clinic judgments during practice or in other medical practice, and their effects on the medical treatment improvements are being proven by previous studies. In the reality of increasing attention in the effects of medical treatment improvement, studies related to hospital DDS were mostly focused on clinical, technical, and engineering points of view, and studies focusing on the user viewpoint are very limited. In order to verify the effects of DSS on practice improvements and hospital's management performance, this study used a research model constructed to verify how SERVQUAL of hospital DSS affects hospital management performance in BSC (Balanced Score Card) point of view. To empirically verify the research model, a questionnaire was conducted on the basis of "K-University Hospital's DSS" on clinicians and hospital employees related to system development, and the relationships between the factors were analyzed through path analysis. As a result of path analysis, excluding reactivity, tangibility, confidence, reliability, empathy among service qualities, had partially significant effects on management performance factors (learning and growth, internal process, financial affairs). This study is to prepare the theoretical ground on the management performance analysis of hospital DSS, and suggest the service quality of the system that should be considered in the planning and development stages for improved system.

This paper is aimed at proposing a new approach to connecting the measurements of customer satisfaction on healthcare services with the prioritized identification of healthcare service processes to be improved. As customers' requirements for healthcare services have become too diverse and healthcare service systems have been increasingly complex, there has been growing interest in the customer-oriented evaluation of healthcare service quality and the systematic improvement of healthcare service processes. Most of the previous studies on service quality evaluation are based on SERVQUAL model. However, because of the unique characteristics and constraints inherent in healthcare service systems, it has been reported that SERVQUAL would be inadequate to be applied to healthcare service systems. As an alternative, SERVPERF has recently been widely used in the evaluation of healthcare service quality. However, there is a lack of studies on how to use the measurements of healthcare service quality systematically to improve service functions and processes. With this issue in mind, we firstly measured the customer-perceived satisfaction on the healthcare service quality from the six dimensions based on SERVPERF. Then we identified the relationships between the subjective measurements and healthcare service processes through brainstorming and expert interview. By using the relationships, we developed a customer journey map in healthcare services that visually describe the interaction between customers and healthcare service systems. The developed customer journey map would help service designers easily identify a healthcare service process that needs to be improved with priority. It is expected that the design improvement process proposed in this study would be a useful method for enhancing the quality of healthcare services.
