Many agile practices have been suggested for software development flexible enough to adapt to a rapidly changing environment. However, too many agile practices hinder computer engineers from deciding which agile practices are suitable for a given project. They need guidelines of the benefits an agile practice provides for a project, and how many of its benefits are effective. Therefore, this study investigates IT experts' perspectives on each agile practice's effectiveness in their projects using a repertory grid technique. Based on an analysis of data collected from 23 Korean IT experts about 33 agile projects, we elicit 361 cognitive effects categorized into 30 benefits using content analysis. Next, we identify agile practices that are primarily used and recognized as positive and further examine what benefits many agile practices usually bring. Finally, we evaluate the level of benefits overall that each agile practice provides.

The revised "Software Industry Promotion Law" has been effective from 2013. This law is to be basis of the domestic public information sector and increases the opportunities for small and medium-sized firms in participating the public IT projects. The shortcomings of this law may be the increase of the risk and the decrease of quality of projects. These suggest that the competencies of project manager (PM) s are critical. Also, in general, an SI (System Integration) project is a one that provides a customer with a customer-tailored system for system integration. Particularly, in an SI project involved in a public institution or a large corporation, the ripple effect of success or failure of a project is becoming greater as the system requires higher cost and more time due to high complexity and large scale. One of the solutions to address these problems is to investigate the competencies of a PM. Thus, in this paper, we derived the major competencies using the RGT (Repertory Grid Technique) and categorized the resultant constructs using the content analysis. In addition, we analyzed the level of importance of competencies by applying the AHP (Analytic Hierarchy Process). The conclusion was that Problem-solving Skill and Leadership were the most important competencies of a project manager.

Current web accessibility checks and automatic assessments have been pointed out that the assessment items and scores are evaluated from the developer's point of view rather than from the user's one. In addition, although most of the grades of an automatic assessment on the public web sites are excellent because they are built in accordance with the web accessibility development guidelines, not a few web sites shows relatively low grades in evaluating their usability test made by those users. Taking into account the inadequacy of these web accessibility assessments, this study has identified the differences between the grades of usability evaluations and automatic evaluations for people with low vision and analyzed the major factors affecting web accessibility usability evaluations using Repertory Grid Techniques. Also, the Hard Laddering method of the Means-End Chain theory was adopted to visualize the relationship between Attributes-Conferences-Value and a hierarchical value system analysis based on FGI(Focused Group Interview) to people with the low vision. This study proposed the measures to improve the current web accessibility automatic assessment allocation, expert evaluation criteria, and user task assessment. In particular, it is a web accessibility user evaluation model that can consider the web accessibility quality certification criteria and user review assessment by directly analyzing the user cognitive structure and value system. This study is expected to be useful as a research to enhance the quality of web accessibility assessment.

This study aims to understand how different construction methods impact scenic preference of green wall and clarify features of each construction method to help select the most suitable construction method for the wanted image of a green wall by providing the basic data for further development and distribution of green wall. Questionnaire developed by the Repertory Grid technique proved that 11 adjectives can be used to describe scenic features of a green wall and 4 preference elements. The result of the Scenic evaluation, the Felt type scored high in 'Aesthetic' and 'Maintenance' meaning that it is the most suitable method when constructing a green wall to improve urban scenery. Regression analysis was conducted to understand the link between the preference elements and scenic impression of a green wall. The result is that the higher the preference is on the design of a green wall, the higher the score is for 'Aesthetic'. Also, the higher the preference is on Bio-Diversity, Design, Growth, the higher the score is for 'Natural'. The above findings can be important measures and reference for selection of the right construction method when planning a green wall.

콜센터 성과평가 및 인적자원 관리는 상담원의 개인적, 사회적 특성을 고려하지 않고 해결 콜 수에만 의존적으로 평가되고 있다. 그러나 콜센터는 대부분 업무가 고객과의 공동 문제해결에 기반하고 있어 상담원의 개인적 역량 및 사회적 역량이 업무성과에 직접적인 영향을 미친다. 따라서 본 연구는 콜센터 상담원을 대상으로 개인적 역량 및 조직 내 사회적 특성이 업무 성과에 미치는 영향을 분석함으로써 콜센터 성과평가 및 상담원의 채용관리에 도움을 주고자 한다. 이를 위해 본 연구는 RGT를 이용하여 개인적 특성을 도출하였고, 네트워크 분석을 통해 사회적 관계를 분석하였다. RGT와 네트워크 분석을 통해 도출된 변수를 바탕으로 회수실적과의 상관계수가 높은 항목을 선정한 후 회귀 분석을 실시하였다. 실험 결과, 회식망 내향 중앙성, 업무 적극성, 개방적 성향, 배우는 것을 즐기는 성향의 네 가지 특성이 회수실적에 유의미한 영향을 미치는 것으로 나타났다. 본 연구 결과는 콜센터 상담원 성과평가 뿐 아니라 상담원의 채용 및 관리에도 의미있는 정보를 제공할 수 있을 것으로 기대된다.

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.

The IT outsourcing industry has been widespread for decades since the growth of the system integration industry stagnates and companies need to curtail expenses and improve the quality of IT services. According to previous studies on the success factors of the IT outsourcing, its transition phase is significant because of continuity of business and the handover of knowledge. Since a transition phase consists of several projects, but its goal is different from general projects, it needs special and professional management. Therefore, recent IT outsourcing business starts to introduce PMO (project management offices), of which success strongly depends on the competencies of the PMO. However, there are only few studies on which competencies of the PMO are important. In this paper, we suggest an evaluation model of transition PMO competencies derived using the repertory grid technique and the analytic hierarchy process. Additionally, we compare the differences between the views of several stakeholders on the importance of the competencies.

The purpose of this study is to suggest designing goals and directions in the lobby area of obstetric hospitals by constructing a space evaluation structure model, which is made by image evaluation structure model used by SD method and Advanced Repertory Grid Technique. As a result of the image evaluation used by SD method, it turned out 4 factors which are related to recognizing and evaluating the space formativeness, openness, decorativeness, sensitiveness. I found out the relationship between space evaluation structure and the element of interior space. I also suggested detailed designing method based on this relationship. Space evaluation structure model can be applied to designing lobby areas of obstetric hospitals to reconstruct more specific and objective designing goals and standards rather simply designer's sensitive and abstract designing approach.

Although the demand for IT outsourcing (ITO) has increased recently because of the recent recession, concerns about business discontinuity in the transition phase cause companies to hesitate to adopt ITO. Therefore, a guideline to improve the prospects is needed. However, studies on the success factors of the transition phase in ITO are lacking. In this study, we develop an expert hierarchical value map (HVM) of the success of the transition phase in ITO by using cognition scientific methodologies. We empirically verify how success factors affect the success of the transition phase. Specifically, we derive an HVM of main stakeholders by using in-depth interviews and approaches, such as repertory grid technique (RGT) and laddering, based on means-end chain theory. We validate the success factors empirically through a bipolar analysis of RGT. Finally, we determine the most important cluster of success factors through cluster analysis.
