The 1+4 Human Effectiveness Model: Why Success is Built, Not Added

This paper presents the “1+4 Human Effectiveness Model”, a conceptual framework that explains success as a systemic outcome emerging from the interaction and alignment of multiple capacities. The model emphasizes that health is the foundational prerequisite for sustained performance, operating as a continuum of functional capacity that influences execution, persistence, decision-making, and opportunity recognition. Built upon health, the model identifies four interacting factors: Strength, Will, Mental Clarity, and Luck. These factors govern how effectively an individual can execute, persist, make decisions, and leverage opportunities. Importantly, the paper explicitly rejects the compensatory view, arguing that deficits in one factor cannot be offset by excess in another. The framework highlights how systemic imbalance, often rooted in health depletion, leads to predictable patterns of performance decay and failure. By viewing success as a product of balanced and aligned factors, this model offers an alternative to talent-based and motivation-centric models. Preprint – not peer-reviewed. English version.
