In this article we look at the maths associated with individual, team and collective performance is paramount. Mathematical models provide a systematic and quantitative approach to analyse relationships, offering insights that can inform decision-making, optimise performance and enhance overall productivity (Ancona & Caldwell, 1992). By translating complex organizational dynamics into mathematical equations, leaders, managers and researchers can predict outcomes, identify leverage points and design interventions that improve performance. This article introduces various mathematical models that quantify the relationships between performance levels within organizations. By exploring these models, we aim to show how individual contributions associate to team performance and subsequently, collective outcomes. We also discuss the applicability of each model and how they aid in performance measurement and optimisation. Mathematical Models of Performance 1. Additive Model Equation: Desc...
