Regarded as a high-level tactic in soccer, a team formation assigns players different tasks and indicates their active regions on the pitch, thereby influencing the team performance significantly. Analysis of formations in soccer has become particularly indispensable for soccer analysts. However, formations of a team are intrinsically time-varying and contain inherent spatial information. The spatio-temporal nature of formations and other characteristics of soccer data, such as multivariate features, make analysis of formations in soccer a challenging problem. In this study, we closely worked with domain experts to characterize domain problems of formation analysis in soccer and formulated several design goals. We design a novel spatio-temporal visual representation of changes in team formation, allowing analysts to visually analyze the evolution of formations and track the spatial flow of players within formations over time. Based on the new design, we further design and develop ForVizor, a visual analytics system, which empowers users to track the spatio-temporal changes in formation and understand how and why such changes occur. With ForVizor, domain experts conduct formation analysis of two games. Analysis results with insights and useful feedback are summarized in two case studies.

Faultline configurations in top management teams are of vital importance in predicting firm outcomes. Grounded in faultline theory, we hypothesise the positive effects of faultlines through the dual routes of coordination and information processing under conditions of various subgroup configuration types. Second-hand data from publicly traded Chinese information technology firms are used to test our hypotheses. The results demonstrate that TMT faultline strength is positively related to a firm’s short-term performance only when both the number and the balance of subgroups are high and is positively related to a firm’s innovation activities only when the number of subgroups is high and the balance of subgroups is low. This study contributes to faultline theory by enriching the connotation of faultlines with the configurational perspective and advancing the debate on the effects of team faultlines as we reveal the benefits of TMT faultlines.

Over several decades, studies of the relationship between task conflict and team innovation have yielded mixed findings. In the present study, drawing on the resource-based view (RBV), we consider that task conflict can activate a dynamic pool of knowledge resources and argue that the impact of task conflict on team innovation is dependent upon the knowledge integration capacity of a team, which is defined as a team’s ability to effectively combine, capitalize, and utilize the resource pool. A study of 59 teams revealed that, in general, task conflict and team innovation exhibit an inverted U-shape relationship, which was moderated by knowledge integration capability. The implications of our findings with respect to conflict research and conflict management are discussed.
