Abstract:

Purpose – The aim of this paper is to examine whether team-members' psychological proximity affects the degree of teamwork quality and therefore affecting the team performance.

Design/methodology/approach – A survey instrument was developed based on extant literature reviews, and administered among information technology professionals. Collected data were analysed using partial least square (PLS) method.

Findings – Team-members' psychological proximity is found to be significantly related to teamwork quality. The magnitude of relational coefficients between sub-dimensions of psychological proximity and those of teamwork quality turned out to be different from each other.

Research limitations/implications – Psychological proximity is found to critically influence teamwork and performance in IT teams. Also, the four-factor model developed from previous literature is validated for further use. Snowball sampling using IT professionals is the major limitation of this study.

Originality/value – Studies on teamwork quality that employs psychological proximity are scarce. Socialising in workplaces is sometimes viewed as an unproductive activity, however, socialising decreases psychological proximity among team-members, increasing teamwork quality. In addition, examining the psychological proximity in team-members adds to the growing literature on teamwork quality.

Abstract:

Purpose – This study aims to investigate the influences of loyalty and switching costs toward a firm's overall post-adoption behavior in using information system.

Design/methodology/approach – A research model is developed around two constructs found in the literature – loyalty and switching costs – that are most critical in firms' decisions on continued use of the same IS service providing company. It is empirically tested using a survey of IT decision makers in total 102 companies in South Korea. Partial least squares method is used to assess the relationships specified in research model.

Findings – The findings suggest that both loyalty and switching costs have positive influences on the continuous intention to use and the inattentiveness of alternatives.

Research limitations/implications – Findings are based on a single point cross-sectional survey. To further investigate the continuance of specific IT service firms, triangulation will be necessary with longitudinal and qualitative data concerning the process of decision-making, including political and contractual situation.

Originality/value – The study fills the research gap in studying post-adoption behavior at the firm level by empirically testing the duality of loyalty and switching costs.

Abstract:

Purpose – This study aims to investigate the effect of communication effectiveness (CE) on service quality (SQ) leading to relationship quality (RQ) in IT service relationships.

Design/methodology/approach – CE was decomposed into frequency, bi-directionality and quality of communication while SQ was decomposed into functional and technical qualities, and RQ into trust and relationship commitment. An empirical study is conducted testing the nomological research model consists of these dimensions, using survey method collecting data from 144 subjects.

Findings – The findings indicate that good SQ can impact relationship commitment only via the clients' trust, but not directly. Influence of functional quality is stronger on trust but technical quality also maintains significant impact. Detailed findings imply that, while communication is important element influencing perceptions of SQ, quality of bi-directional communication is more critical than simple but frequent communication.

Originality/value – This study explores the direct impact of CE on SQ leading to RQ in IT service context. Previous studies rarely tested the impacts of functional and technical SQ, simultaneously. Findings of this study add values to research on service relations as well as IT services research in terms of differentiating functional and technical service qualities.

Jungwoo Lee, Hyejung Lee, Jungi Park*

 

Abstract

 Although empowering leadership has been known as one of important type of leadership in modern management, few studies have examined mechanisms linking empowering leadership to team performance, particularly in IT service teams. This study empirically investigates the mechanism through which empowering leadership of a team leader might influence the team performance in IT services. A survey was conducted using questionnaire containing items for empowering leadership, knowledge sharing, absorptive capacity and team performance. The research model was analyzed using PLS against 315 data points collected from 85 different IT projects. Results indicates that team leader's empowering leadership raises the level of knowledge sharing among team members and increase the absorptive capacity of the team, and lead to better team performance. Theoretical implications are discussed with practical applications of this theoretical development.

Abstract

Most firms today are served by specialized IT service providers for the development and maintenance of their business information systems. During the IT service encounter, service providers and clients interact throughout the project, exchanging information, sharing knowledge and making critical decisions. From the IT service provider's viewpoint, it is important to raise the level of clients’ relationship commitment during this service encounter as their business continuity depends upon clients assessment. Intuitively, effective communication and effective service quality, mediated by trust, are critical factors in raising the level of relationship commitment. This study proposes an empirical model consisting of four critical antecedents of relationship commitment (communication effectiveness, technical service quality, functional service quality and trust) and then tests the model using data points solicited from two global firms. Study results revealed that trust is a strong mediator for relationship commitment while functional, rather than technical, service quality is a stronger mediator in forming the clients’ trust.

Highlights

► Communication enhances trust, leading to stronger level of relationship commitment from the clients’ perspective in IT services. ► Sound technical service quality is necessary but not sufficiently satisfactory condition in IT services. ► Functional, as well as technical, service quality matters even in IT services. ► Training of consultants on communication skills may warrant retention of clients in IT services. ► Knowledge exchange occurs continuously in IT services, before, during and after the delivery of services.

ABSTRACT: This study applies social capital theory to IT service team environment. The research model of this study includes emotional, cognitive, and social intelligence competencies of project managers (PM) as they lead to the project performance, while team social capital is posited as a mediator between these leadership competencies and team project performance. A PLS analysis of 285 data points collected via a validated questionnaire revealed the followings: (1) emotional intelligence competencies of PM directly influence the project performance, (2) social intelligence competencies of PM indirectly influence project performance only via team social capital, and (3) cognitive intelligence competencies of PM maintains direct influence on project performance in shorter term projects, but indirect influence only via the accumulated team social capital in longer term projects. The analysis also reveals that it takes time to grow team social capital. Implications of the findings are discussed, and further studies are suggested.

Abstract
 Programming skill is becoming more and more important as the information revolution progresses into a knowledge-based smart society. Concept of self-efficacy, which has been known to be critical in raising general competences of work and life, can easily be extended into the learning of programming languages. A survey was conducted to study the mechanisms related to general and specific programming self-efficacy and their antecedents: mastery experience, vicarious learning, verbal persuasion and computer affect. Findings confirm the strong path from general programming selfefficacy towards specific programming self-efficacy indicating the generality of self-efficacy applicable across domains and disciplines. Among four antecedents of programming self-efficacy generally identified in the social cognitive theory literature, mastery experience and vicarious learning are found to be important in reinforcing the programming self-efficacy while verbal persuasion and computer affect seems to be not so strong in forming the self-efficacy towards programming. Further implications and limitations are discussed at the end.

Abstract
 The purpose of this study is to examine the impact of IT service quality on trust, commitment and intention to continuously use the IT service. Service quality in this research is measured in two dimensions (technical and functional) while trust measured in two dimensions (cognitive and affective). An empirical model is proposed here, consisting of technical quality, functional quality, cognitive trust, affective trust, commitment and intention to use. The model was tested using 215 data points collected in a global electronics firm. Study results show that the cognitive and affective dimensions of trust are affected by functional and technical service quality. Interestingly, functional service quality seems to have effects stronger than technical service quality contrary to the expectation that technical quality of outcome would be more important than functional in case of IT services. Also, affective trust seems to maintain stronger effects than cognitive trust in raising the commitment level of IT service client. Further implications and limitations are discussed.

Abstract
 With the fast proliferation of internet protocols with infiltration of smart devices, information and communication technology (ICT) is changing every aspect of our work and life. Social informatics is a discipline of interdisciplinary investigation concerning changes incurred by ICT. The scope and boundary of social informatics being an emerging field of investigation have not yet been adequately defined due to its broad and ambiguous nature. The purpose of this study is to develop a conceptual framework for social informatics research based on a review of actual studies from the perspective of our work and life. Content analysis was performed to extract keywords and categories from research articles published in major academic journals related to social informatics within the last decade. A conceptual framework is surfaced with four major categories (Technology & Use, Government, Level of Context and Social Issues) and 13 subcategories. In conclusion, the direction of social informatics research is proposed and implications are discussed with limitations of the study.

Abstract
 Recently, firms begin to adopt smart work practices including telecommuting and flexible time. This trend is triggered by recent rapid advent of smart devices with common connectivity through the Internet. As smart work infiltrates our society, IT service is now becoming more of a norm rather than exception for business firms, aiding business users to work smarter. In IT services in which knowledge professionals are involved, the quality of services determine the perceived value of the service while this value perception contributes to the service users’ satisfaction and intention to continue to use the service. Using notions of core and peripheral services commonly used in traditional service research, a hypothesized research model is built for this study, relating core and peripheral service quality, perceived service value, service satisfaction, and intention to continue use of IT services to each other. Structural equation modeling (SEM) was used to analyze 295 data points collected through a survey of global electronics company employees who are extensively using IT services. Findings indicate that the quality of the core services had a positive impact on both the IT satisfaction and IT service value, while peripheral services had a positive impact on the IT satisfaction only. Furthermore, no relationship was found between IT service value and IT satisfaction. However, the value of and satisfaction with IT services were found to have a positive influence on the intention to use the IT services.

고객 관계 경향, 신뢰, 몰입 그리고 재사용 의도: IT서비스의 경우

박준기 이혜정 조철현 디지털정책연구 = The Journal of Digital Policy & Management v.10 no.9 , pp.137 - 149 , 2012 | 1738-1916

한국어 IT서비스 기업들은 기존고객을 유지하면서 새로운 잠재고객을 확보하기 위해 고객과의 긍정적 관계 형성이 필요하다. 특히, IT서비스는 경험해 보지 않고서는 서비스의 품질을 평가하기 어려운 지식정보재화의 특성을 거래대상으로 하기 때문에 고객의 입장에서 새로운 서비스제공자를 찾기 보다는 한번 맺은 관계를 지속적으로 유지하고자하는 경향이 있다. 따라서 본 연구에서 IT아웃소싱 환경에서 고객 관계 경향이 고객과 서비스 제공자간의 신뢰와 몰입, 그리고 재사용 의도에 어떠한 영향을 미치는지를 분석하였다. 이를 위해 IT아웃소싱 서비스를 경험한 글로벌 전자부품 기업 구성원 200명에 대한 설문자료를 PLS 분석방법을 사용하여 분석하였다. 그 결과, 고객 관계 경향은 신뢰와 몰입, 서비스 재사용성 모두에 정의 영향을 주고, 신뢰는 몰입에, 몰입은 재사용의도에 각각 정의 영향을 주는 것으로 나타났다. 반면, 신뢰는 재사용 의도에 정의 영향을 미치지 않는 것으로 나타났다. 이러한 결과를 바탕으로 고객 관계 경향에 대한 함의와 미래 연구를 위한 논의를 제시한다.
영어 It has become a crucial issue for IT service firms how to form positive relationships with their customers in order to retain existing customers and potential customers. To address this issue, many researchers have introduced the concept of consumer relationship proneness(CRP). This present study examines if CRP is related to trust and commitment that enhance the intention to reuse. Using PLS, we analyzed 200 data collected through a survey of global electronic company members experienced IT outsourcing services. As a result, CRP has a defined impact on both trust and commitment, and relationships between trust and commitment, commitment and reuse intention have a positive effect. On the other hand, trust does not affect reuse intention. Based on these results, it presents a discussion for future research and the implications for CRP.
