The field of global leadership has flourished and advanced in the preceding decade. However, in contrast to the term global leadership, which enjoys conceptual clarity enabling accumulative progress, the construct of global leadership effectiveness is comparatively undertheorized, with instances of definitional ambiguity and disjointed methodological operationalizations across studies. The purpose of this chapter is, thus, to provide a systematic review of the global leadership effectiveness literature. In doing so, our contributions are fourfold. First, we offer an inclusive, comprehensive definition of global leadership effectiveness. Second, we map its construct domain. Third, we review research findings at the individual, group, and organizational levels. Finally, we integrate extant insights and offer suggestions for future research, organized within the typology of the content domain along the identified dimensions of global leadership effectiveness. Together, our goal is to build a foundation for future research examining the roles of leadership and the global context as antecedents of global leadership effectiveness.

This study aims to determine whether it is possible to use information and communication technology (ICT) tools to share tacit knowledge. Few studies have considered this subject, and they have reported both the ineffectiveness and effectiveness of ICT tools for sharing tacit knowledge.

In this study, the participants comprised 217 knowledge workers from New Zealand and researchers who attended a knowledge management conference in the UK. In all, 59% of the sample was men and 41% women. The research model compared the scores of knowledge workers in two categories of ICT, those that allow dialogue and those that do not, in relation to knowledge sharing in organizations. The instrument used a Likert scale with five levels of response.

It was found that not all ICT technologies let tacit knowledge to be shared, but those ICT that facilitate dialogue, for example, text messaging and video conferences. Emails did not facilitate the exchange of tacit knowledge.

It is suggested to replicate the study with different countries to evaluate the role of culture in the communication of tacit knowledge.

An implication for practitioners based on this study is that email should not be the preferred mode for transferring knowledge between an organization and their workers. This mode is adequate for the exchange of explicit knowledge, but it has a limited capacity for transferring tacit knowledge. Thus, organizations may increase the use of audio and video tools to transfer electronically tacit knowledge. Interaction or socialization may facilitate the understanding and internalization of tacit knowledge by workers.

This study contributed to understand the reason for contradictory results from previous research. ICT tools are effective to share tacit knowledge when they facilitate dialogue. Results also support practitioners about how to obtain more effective exchange of tacit knowledge in organizations.
