Abstract

With the revitalization of non-face-to-face transactions, the difference between the size of branches and transaction costs among securities firms has decreased, and the importance of the stock trading system has increased. In particular, the mobile trading system has become more important due to the increase in the proportion of transactions in the mobile trading system, which is widely used by individual investors, and the increase in the number of individual investors after COVID-19. However, user-centered usability studies are insufficient as usability studies on mobile trading systems are conducted through literature surveys or survey methods. Therefore, in this study, a repertory grid technique that finds user's empirical perception was used to find out user-centered usability attributes. The usability attributes of the mobile trading system from the user's point of view were elicited, and the difference in the usability attributes in terms of frequency and importance between the user group and the developer group was identified.

비대면 거래 활성화로 증권사 간 영업점포 규모나 거래 비용면의 차별성은 줄어들고 증권거래 시스템에 대한 중요성이 높아졌다. 특히 개인 투자자들이 많이 사용하는 모바일 트레이딩 시스템의 거래 비중 증가와 코로나19 이후 개인 투자자의 증가로 모바일 트레이딩 시스템은 더욱 중요해졌다. 하지만 모바일 트레이딩 시스템에 관한 사용성 연구는 문헌조사나 설문조사방법으로 진행되어 사용자 중심의 사용성 연구는 부족하다. 이에 본 연구에서는 사용자 중심의 사용성 속성을 알아보기 위해 사용자의 경험적 인식을 찾아내는 레퍼토리 그리드 기법을 사용하였다. 사용자 관점의 모바일 트레이딩 시스템 사용성 속성을 도출하고 사용자 그룹과 개발자 그룹간의 빈도와 중요도 측면에서 사용성 속성 차이를 확인하였다.
