TEAM PERFORMANCE LIFE HACKS FROM DIFFERENT COUNTRIES: A COMPARATIVE ANALYSIS OF PRACTICES AND TRANSFER CONDITIONS

Team effectiveness has long ceased to be an abstract management category. In the context of digitalization, distributed teams, and accelerated business processes, it is becoming a matter of organizational survival. Meanwhile, so-called "life hacks"—short-form management techniques promising a quick boost to team performance are actively circulating in the professional community. However, the simplicity of these solutions often conceals deep institutional and cultural assumptions, without an understanding of which, their mechanical replication will not produce the desired effect. This article aims to comparatively analyze team effectiveness practices developed in different countries and to identify the conditions for their effective transfer to other organizational contexts. It examines management approaches related to the culture of continuous improvement, decision-making models, accountability structures, the nature of feedback, and the level of trust within the team. Particular attention is paid to how national communication patterns, institutional environments, and management traditions influence the sustainability of these practices. The results show that there are no universal "life hacks": the same practice can boost productivity in some contexts and cause resistance or formalization in others. Team effectiveness is determined not by a set of trendy tools, but by alignment of goals, clarity of responsibility, and the system's ability to learn from its own mistakes.
