This article discusses how Key Performance Indicators (KPIs) are applied in sports—particularly team sports—to evaluate performance at various levels, including teams, staff, and individual athletes. It outlines four major issues in the application of KPIs:
Lack of a Universal Definition: There's no standard definition of what constitutes a KPI in sports.
Complexity of Performance: Team sports involve dynamic and complex interactions, making it difficult for KPIs to fully capture true performance.
Drift from On-Field to Off-Field Goals: Sometimes KPIs focus more on administrative or off-field metrics instead of core on-field performance goals.
Agency and Stakeholder Issues: Different stakeholders (coaches, players, analysts) may have conflicting priorities in what they consider important to measure.
