Operational management involves planning, organizing, and controlling the processes that transform inputs into finished goods and services. It has evolved from early concepts like the division of labor and standardized parts to modern approaches like just-in-time manufacturing, supply chain partnering, and mass customization. Operational management occurs at three levels - strategic, tactical, and operational. The strategic level focuses on high-level issues like plant locations, the tactical level addresses areas like equipment selection, and the operational level involves daily activities such as production scheduling and quality control. Competing based on cost, quality, flexibility, and speed are important considerations for operational management.
