Scientific management aimed to improve industrial efficiency. Frederick Taylor developed its core principles: (1) scientifically analyze each job element; (2) scientifically select and train workers; (3) cooperate with workers; (4) equally divide work and responsibility. The Gilbreths used time-motion studies to standardize processes. Henry Gantt focused on production scheduling using Gantt charts. While scientific management improved productivity, it was criticized for treating workers like machines and excluding senior management tasks.
