Exploring the impact of empowering leadership on knowledge sharing, absorptive capacity and team performance in IT service

Purpose – The purpose of this paper is to empirically investigate the mechanism through which empowering leadership of a team leader might influence the team performance in IT service. Design/methodology/approach – The data of 315 individuals collected from 85 different IT projects through online survey is used to empirically test the hypotheses. Findings – The results confirm 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. Research limitations/implications – This research theoretically presented and demonstrated the middle- and long-term impacts of empowering leadership resulting from the development of absorptive capacity as the effects of knowledge sharing in an IT project team are produced through absorptive capacity. Practical implications – The findings indicate that more effective in increasing the performance of IT project teams can be to strengthen empowering le...

Explaining knowledge sharing with social capital theory in information systems development projects

Purpose – Owing to their complex and knowledge-intensive nature, information systems development (ISD) projects require effective collaboration between business and technology experts. In this regard, social capital theory may provide a valuable framework and insight into explaining knowledge sharing behavior in an ISD context. The purpose of this paper is to expand the theory of knowledge sharing as developed thus far in the ISD project context using the full-blown team social capital theory. Design/methodology/approach – The expertise and communication effectiveness of business and technology professionals were posited as antecedents of team social capital and knowledge sharing. The research model for this study integrates expertise, communication, knowledge sharing, social capital, and team performance into a structural equation modeling. The research model was empirically tested with a data set from business and technology professional pairs collected from 115 ISD project teams. Findings – The results...

Leadership Competencies of IT Project Managers : from Team Social Capital Perspective

Abstract 논문투고일：2011년 10월 18일 논문수정완료일：2011년 12월 13일 논문게재확정일：2011년 12월 18일* 본 연구는 2009년도 교육과학기술부의 재원으로 한국연구재단의 지원을 받아 수행된 기초연구 사업임(No.KRF- 2009-327-B00208).** 연세대학교 정보대학원*** 연세대학교 정보대학원 교수, 교신저자This study explores the applicability of social capital theory in IT project management. Specifically, an empirical model is developed using different types of leadership competen cies (emotional, cognitive, and social) as independent constructs impacting IT project performance. Social capital sha red among team members are measured and placed as a mediating construct between leadership competencies and pe rformance. Using PLS analysis of 120 data points collected through a survey of IT project participants in two la rge electronic manufacturers, direct and indirect impacts of leadership competencies are explicated. Research results rev eal that emotional leadership competency seems to directly influence the project performance but not through team social capital, while social leadership competency seems to indirectly influence the project performance through t eam social capital but not directly onto the project performance. Cognitive leadership competency is the only leader ship competency that maintains direct and indirect influence on project performance. Total effect of cognitive com petency on project performance is almost two times larger than the total effect of emotional leadership competency and six times larger than the total effect of social leadership competency. Implications of findings are discussed at the end, and further studies are suggested.

Applying social exchange theory in IT service relationships: exploring roles of exchange characteristics in knowledge sharing

AbstractExtending the social exchange theory which emphasizes trust and dependence as important in building and maintaining relationships, exchange specific characteristics (relationship investments and benefits) are additionally posited here as critical antecedents in knowledge sharing relationship among IT service team members, along with partner characteristics (expertise and value similarity) and interaction (communication frequency). An instrument was constructed and administered against client side project leaders in three different IT service firms. Analyses of 126 data points revealed that relationship benefit, investments, and expertise are strongly associated with dependence while relationship investment, expertise and value similarity are strongly associated with trust in IT service relationship. Findings confirm that the exchange characteristics suggested by the social exchange theory plays important roles in building and maintaining dependence in IT service relationships and, in turn, towards building trust for knowledge sharing, but only indirectly via dependence. Also, paths from dependence to trust and knowledge sharing are confirmed as suggested by previous studies. Results implies that the benefits and investments for and in IT service relationship needs to be cultivated, exposed and emphasized in order to increase the necessary knowledge sharing levels. Limitations of the study are discussed with suggestions for further studies into social exchange characteristics in the conclusion.

Work Design Characteristics of Mobile-Intensive Workers: Implications for Future Work Design

Modern Work Design Theory (WDT) presumes that different characteristics of work (motivational, social, and contextual) influence attitudinal outcomes of workers such as job satisfaction, thus work needs to be designed carefully with these characteristics taken into consideration. Moreover, increased adoption of ICT also changes these work characteristics as it provides capability to overcome physical limitations such as time and place. Recent rapid infiltration of smart devices connected to the Internet brings telecommuting and flexible time back into reality, hence “smart work” and “work smart” are becoming another catchphrase of consulting firms. This study extends the work design theory with ICT use. WDT variables are empirically tested against two different ICT user groups: one with mobile messenger use and another with PC messenger use. Mobile messenger use is treated as the surrogate of mobile working, expecting mobile messenger users are more subjected toward smart work while PC messenger users are relatively traditional workers at a fixed place. Meaningful differences are found in terms of motivational, social, and contextual work characteristics. Also, job satisfaction is found to be critically high for smart workers. Autonomy and interdependence are much higher for mobile messenger users while complexity of work is found to be much higher for PC-based messenger users. Results indicate the work design theory developed in industrial setting may also be applicable in information- and knowledge-based smart work setting. Further research and limitations are discussed at the end with practical implications.

Explicating Moderating Effects of Conflict in the Psychological Mechanism in IT Service Engagement

논문투고일:2013년 10월 25일 논문수정완료일:2014년 03월 07일 논문게재확정일:2014년 03월 12일 * 본 논문은 2012년 정부(교육부)의 재원으로 한국연구재단의 지원을 받아 수행된 연구임(NRF-2012S1A3A2033474). ** 연세대학교 워크사이언스연구센터 객원연구원 *** 연세대학교 박사과정 ****연세대학교 교수, 교신저자 In IT service quality research, the relationship between the service quality and clients’ satisfaction was the focus of many studies while in relationship quality research, the influence of trust and conflict on relationship commitment seems to be the focus. In this study, these two research streams are integrated and a theoretical research model is proposed consisting of IT service quality, satisfaction, trust and relationship commitment with conflict as a moderator for the overall psychological mechanism. As satisfaction represents emotional response while trust cognitive response, this research model integrated both emotional and cognitive aspects of relationship maintenance in the IT service context. Analysis of data collected from 262 employees of global IT service firm revealed the differential effects of reliability, responsiveness, assurance and empathy on satisfaction and trust. Also, depending upon the level of conflict, the effects of reliability and assurance were found to be moderated. Further analysis revealed more profound mechanism at work relating emotional and cognitive aspects in the psychology of relationship maintenance in IT service context. Practical implications are further discussed in the conclusion.

Exploring the Impact of Leadership Competencies on Team Social Capital and Performance in IT Service Team

This study applies social capital theory to IT service team environment. Research model of this study includes emotional, cognitive, and social intelligence competencies of project managers leading to project performance while team social capital posited as a mediator between competencies and performance. PLS analysis of 285 data points collected via a survey revealed: (1) emotional intelligence competencies directly influence project performance but maintains no indirect influence via team social capital, (2) social intelligence competencies indirectly and strongly influence project performance via the social capital among team members, but maintains no direct influence, and (3) cognitive intelligence competencies maintains both direct and indirect influence. Analysis also reveals that it takes time to grow team social capital. Teams involved in longer term IT service project maintains higher level of team social capital compared to shorter term projects. Implications of findings are discussed at the end, and further studies are suggested.

Cognitive and Affective Trust in IT Consulting Service

As IT consulting is one of the knowledge intensive services requiring high credence on both sides, maintaining a good trustful relationship is critical in sustenance of strategic partnership between business firms and IT service firms. Trust is known to be one of the salient constructs in service relationships. In this study, building from the social psychology literature, trust is conceptualized as two dimensions : cognitive and affective trust. Using two dimensions of trust as mediators, a research model is constructed for IT consulting specific context : relationship continuance intention as the dependent construct while expertise, service performance, reputation, relationship satisfaction and value similarity as antecedents of cognitive and affective trust. 145 data points were collected through a survey of IT service client project managers retrospectively asking their experience with IT consultants. Findings suggest that cognitive trust is associated with perceived level of expertise and service performance while affective trust with relationship satisfaction and value similarity, respectively. Interestingly, the paths from reputation are found to be statistically insignificant towards both dimensions of trust, indicating IT service context would be more practically outcome oriented than any other professional service context. Also, cognitive trust seems to maintain stronger influence on relationship continuance intention as anticipated. Implications and limitations are discussed at the end.

Exploring Antecedents of Knowledge Sharing in Team-based Innovation Activities

Innovation becomes norm rather than exception in today`s business, and accordingly firms are working on how to make their employees to work smarter using information systems and technologies. Smart work demands virtual collaboration and cooperation among team members in different places and different time. Sharing of knowledge among team members in these innovative activities are critical in every sense for the successful performance. This study explores the antecedents of knowledge sharing among team members in team-based innovation activities. Five factors (pleasure of knowledge sharing, self-efficacy, management support, rewards, and system usage) are identified through extant review of literature and an instrument is adopted and validated from previous studies. The instrument is adminitered against 138 individuals in and across 54 teams in a telecommunication firm. Except self efficacy, all the paths in the proposed research model is confirmed with different levels of relational coefficients towards the levels of knowledge sharing and innovation activities in teams. Surprisingly, findings indicate that intrinsic pleasure of sharing is most critical than management support, organizational rewards or system usage. This study fills the research gap in team management. Findings provide important implications for managing teams in coming virtual and smart environment.
