Scientific management, attributed to Fredrick Taylor, is a theory of management that focuses on improving economic efficiency, particularly labor productivity, by analyzing and synthesizing workflows. It is sometimes referred to as 'stop-watch management' due to Taylor's focus on breaking down manufacturing tasks into short, repetitive segments to enhance efficiency and profitability.
