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.

This study examines how experience diversity of chief technology officer (CTO) drives radical innovation of the firm, and the moderation effect of group attributes of top management team. Using data of 148 firms in U.S. manufacturing industries, this study finds that a CTO's diverse functional experience increases a firm radicalness, and diverse industrial experience also increases the radicalness. This study also examined the moderating effect of top management team (TMT) characteristics such as TMT size, TMT tenure, and gender composition in TMT. The positive relationship of CTO knowledge diversity and firm radicalness is weakened as TMT size or TMT tenure increased while the relationship is strengthened as gender diversity in TMT increased. These results of the analysis of firm-level radicalness provide implications for both academics and practitioners.

Purpose: The purpose of this study is to propose the product quality satisfaction index based on multiple linear regression using customer reviews. Methods: The proposed framework is composed of four steps. First, we collect online reviews and divide it into insight phrases. The insight phrases are classified using product attribute dictionary and sentiment analysis is conducted. Second, the importance of attributes is calculated in consideration of both regression coefficient and frequency. Third, the positive rate is calculated concerning sentiment analysis result. Therefore, the quality satisfaction index is measured by the weighted sum of importance and positive rate in the last step. Results: We conduct a case study using 2-years(2020, 2021) of Samsung TV reviews to confirm the effectiveness of the proposed methodology. As a result, we found that Picture quality is the most crucial attribute in TV evaluation. The importance of Gaming and content has grown up as the positive rate has also increased. Therefore, the overall satisfaction of TV has increased in 2021 compared to 2020. Conclusion: The result of this study shows that the proposed index reveals the customer's mind efficiently and can be explained by the importance and positive rate of each attribute. By using the proposed index, companies are able to improve and the priority of improvement can be determined.

This work identifies the key factors influencing the success of multidisciplinary, interdisciplinary, and trans-disciplinary R&D projects in transition economies by integrating knowledge management, organizational, inter/intra-collaboration (open-innovation), and leadership perspectives, while also addressing the perspective of the science of team science, which is an integrative approach to R&D. This is followed by providing the major sub-constructs of team science and policy implications to better facilitate multidisciplinary, interdisciplinary, and transdisciplinary R&D projects in knowledge-based transition economies.

Given the large investment and prevalence of knowledge management (KM) in organizations, it has become important to analyze the effects of KM activities on organizational performances. A theoretical framework is proposed to investigate the impact of KM activities on innovation capabilities in the IT service industry. This study considers KM activities as the major determinant that enhances absorptive capacity. KM activities enhance employees'ability to obtain external knowledge, resulting in increasing intellectual capital. Thus, this study proposes that absorptive capacity plays a mediating role between KM activities and innovation capability. Additionally, this study investigates the key antecedents of KM activities that promote employees' knowledge sharing. Based on prior studies on KM, this study posits KM team activities and top manager support as KM activities. The proposed research model was tested by using survey data collected from 556 employees in the IT service industry. PLS (partial least squares) was employed for the analysis of the data. The findings of this study showed that KM activities and absorptive capabilities play a significant role in enhancing service innovation and process innovation in the IT service industry. The results also shed light on the mediating role of absorptive capacity between KM activities and innovation capability. Moreover, both KM team activities and top manager support serve as the salient antecedents of promoting employees' knowledge sharing.

Leader-Member Exchange (LMX) model of leadership has suggested that members within the same work team are differentiated in terms of their level of the quality of leader member relationships. However, the differentiation in leader member relationships has not been examined for its possible team-level effects. In this study, the possible impact of this role differentiation on team members' affective reactions was explored. As hypothesized, teams whose members experienced higher level of LMX tended to have higher overall job satisfaction, organizational commitment, and team efficacy. Contrary to expectation, however, the team-level mean on LMX was not related with team-level variability on LMX. Based on these findings, several theoretical and practical Implications are discussed.

SI 프로젝트에서 품질을 혁신하기 위해서는 시스템 생명 주기 각 단계에서 품질 관리 활동을 강화해야 할 뿐만 아니라 통합된 시스템 관점에서 각 계층(Layer)별, 요소(Component)별 특성을 고려하여 체계적인 시스템 진단 평가 활동을 수행할 필요성이 있다. 시스템 진단 평가 활동은 품질 이슈를 찾아내는 작업과 품질 이슈를 해결하는 작업이 톱니바퀴처럼 맞물려 수행되어야 한다. LG CNS는 프로젝트의 품질 이슈를 적기 진단하기 위해서 시스템 진단 평가 체계를 구축했으며, 프로젝트 현장에서 이를 적용하여 품질 혁신에 기여하고 있다.

After being introduced "4th Industrial Revolution" in the Davos Forum 2016, it is continuously talked about "4th Industrial Revolution" as an industrial and social innovation momentum for solving structural problems of economy and society. In this situation, our government established "the Committee of 4th Industrial Revolution" as a control tower and announced a policy "4th Industrial Revolution recommendation for government" in 2019. The Ministry of National Defense is pursuing "4th Industrial Revolution" policies and organizing a team "4th Industrial Revolution Smart Defense Innovation Team" in accordance with government-wide policies from 2019. In this paper, I will look at the background and status of the Smart Defense Innovation policy. And I am proposing development plans to create practical results as like "Strengthening governance for the Smart Defense Innovation" and "Implementation of the budget for the Smart Defense Innovation" and so on.
