    Study Notes

    Lean Manufacturing

    • Lean manufacturing is a production philosophy that aims to minimize waste and maximize value-added activities to create a more efficient and effective production system.

    History of Lean Manufacturing

    • Lean manufacturing originated in the 1950s at Toyota Motor Corporation, led by Taiichi Ohno and Shigeo Shingo, as a response to the limitations of mass production systems.
    • The Toyota Production System (TPS) was developed, focusing on the elimination of waste, continuous improvement, and respect for people.

    Fordism and Sloanism

    • Fordism, pioneered by Henry Ford, emphasized standardization, specialization, and efficiency in production, but led to inflexibility and quality issues.
    • Sloanism, developed by Alfred P. Sloan Jr. at General Motors, focused on the efficiency of mass production systems, but neglected waste reduction and flexibility.

    Lean Waste

    • Lean waste refers to non-value-added activities in the production process, categorized into eight types:
      • Transportation waste
      • Inventory waste
      • Motion waste
      • Waiting waste
      • Overproduction waste
      • Overprocessing waste
      • Defect waste
      • Skills waste

    Value Stream Management

    • Value stream management is a key concept in lean manufacturing, aiming to optimize the flow of materials and information across the entire value stream, from raw materials to end customers.
    • It involves identifying and eliminating waste, improving flow, and enhancing customer value.
