Enterprise Social Networks (ESN) have emerged...

Regulations to contain the spread of COVID-19 have affected corporations, institutions, and individuals to a degree that most people have never seen before. Information systems researchers have initiated a discourse on information technology's role in helping people manage this situation. This study informs and substantiates this discourse based on...

Organizations have increasingly turned to the use of virtual teams (VTs) to tackle the complex nature of today’s organizational issues. To address these practical needs, VTs researchers from different disciplines have begun to amass a large literature. However, the changing workplace that is becoming so reliant on VTs comes with its own set of mana...

Purpose Enterprise social networks (ESN) are increasingly used by companies to reinforce collaboration and knowledge sharing. While prior research has investigated ESN use practices, little is known about potential user roles emerging on these platforms. Against this backdrop, this paper develops an ESN knowledge actor role framework. Design/metho...

The relationship between social network sites and social capital has received much research attention. However, two research gaps can be identified in the existing literature. First, only few studies have examined online social capital as a resource in online social networks. In this regard, it is not clear how to validly measure online social capi...

Aufgrund des großen Erfolges von sozialen Medien im privaten Umfeld beschäftigen sich auch Organisationen zunehmend mit dem Potenzial sogenannter Enterprise Social Software (ESS). Im Organisationskontext kann ESS dazu beitragen, dass die Kommunikation transparenter und schneller, die Zusammenarbeit effizienter und die Unternehmenskultur partizipati...

Despite the large number of resources that blockchain has, and continues to mobilize, it is not yet fully understood what makes the technology unique and why people engage with it. Hence, “Why Blockchain?” is a question that many scientists and managers still ask themselves or have to answer when facing the technology's critics. While the question...

At the latest since the COVID-19 pandemic, the notion of ‘resilience’ has become omnipresent. As Information Systems (IS) researchers, we are particularly interested in how IS can contribute to coping with exogenous shocks like the pandemic and help organizations and societies to become more resilient. However, a comprehensive overview of how resil...

The COVID-19 pandemic accelerated the implementation and adoption of new features in web-conferencing systems (WCSs), such as custom backgrounds (CBs) that mask the real physical background with a custom, i.e., user chosen, background. In this work, we explore what types of backgrounds are selected and why they are used by analyzing text and images...

Angesichts der zunehmenden Konkurrenz durch Online Shops ist die Schaffung eines ganzheitlichen Kundenerlebnisses (engl. Customer Experience) für stationäre Einzelhandelsunternehmen von besonderer Bedeutung. Hierbei geht es darum, eine positive Wahrnehmung einzelner Einkaufserlebnisse beim Kunden zu erzielen – über die Produkte, den Service und die...

Along with the increasing number of companies introducing Enterprise Social Networks (ESN) in recent years, research on ESN user behaviour has proliferated. Yet, a detailed analysis of factors driving ESN user behaviour, that is, how users participate in ESN, is missing. Addressing this gap, in this paper, we explore ESN user behaviour and factors...

Traditionally, knowledge management initiatives in organizations have focused on the conversion of tacit into explicit knowledge with the goal to capture and store this knowledge in repositories. Many of these attempts to manage knowledge have failed, one possible reason for that being the negligence of the social context of knowledge work. Offerin...

The analysis of user behavior in online communities is a prominent topic in social media research. As such, user behavior is often analyzed using a set of metrics that describe the user’s participation behavior and structural position in the social network. Yet, for Enterprise Social Networks (ESN), i.e. internally used social networking platforms,...

In this paper, we explore the discriminability of psychometrics derived from an automated linguistic analysis within a business setting. To this end, a commercial natural language processing application is used to analyse messages posted to the Enterprise Social Network (ESN) of an Australian professional services firm. Comparing the psychometrics...

Enterprise Social Networks have a similar set of functionalities as social networking sites but are run as closed applications within a company's intranet. Interacting and communicating on the Enterprise Social Networks, the users, i.e. a company's employees, leave digital traces. The resulting digital record stored in the platform's back end bears...

The identification of distinct user roles is an important theme in social media research.
