Production planning originated during the Industrial Revolution to manage mass production more effectively. Key figures like Frederick Taylor and Henry Gantt pioneered early techniques, with Gantt's chart revolutionizing task scheduling. The demands of World War II advanced systematic planning approaches. The mid-20th century saw computers enhance precision and data analysis, leading to the development of complex planning software. Enterprise Resource Planning (ERP) systems emerged later, integrating various business processes. In the 21st century, advancements in AI, machine learning, and IoT have further evolved production planning, making it more adaptive and efficient.
