Zusammenfassung:
The rapid digital transformation in the telecommunication industry has underscored the importance of webtop applications as productivity enablers. This study examines the impact of key webtop application features-User Interface Usability (UIU), System Integration (SI), Real-Time Data Access (RTDA), and Collaboration Features (CF)-on Employee Productivity (EP) in Bangladesh's telecommunication sector. Grounded in the Task-Technology Fit (TTF) theory, the study investigates the mediating role of Knowledge Sharing (KS) and the moderating role of Technology Training Availability (TTA). Using a quantitative research approach, data were collected through structured surveys from 384 employees in the telecommunication industry and analyzed using Smart-PLS 4.0. The findings reveal that all webtop application features significantly enhance EP, with KS mediating these relationships. TTA positively moderates the effects of RTDA and CF but shows a negative moderation for UIU and no significant impact for SI. The study's novelty lies in its comprehensive exploration of webtop applications within a developing economy, addressing both the technological and human dimensions of productivity. Recommendations include fostering a culture of knowledge sharing, optimizing training programs to match technological complexity, and investing in feature-rich, integrated systems to enhance organizational performance. This research offers actionable insights for managers, policymakers, and academics, providing a robust framework for leveraging digital tools to enhance productivity in modern workplaces. The study contributes to the theoretical discourse by extending the TTF framework and provides a practical roadmap for technology adoption and workforce development in rapidly digitalizing industries.
