Continuous Improvement: Lean

  1. Lean: Lean is a systematic approach to eliminating waste and maximizing process value. Originally developed by Toyota in the 1950s, Lean principles have since been widely adopted across industries. The core idea behind Lean is to focus on creating more value for customers with fewer resources. Key principles of Lean include:

    • Identifying Value: Understanding what activities and processes add value from the customer’s perspective.
      価値の特定: 顧客の視点から、どのような活動やプロセスが付加価値を生むかを理解する。
    • Value Stream Mapping: Visualizing the entire process flow to identify and eliminate non-value-added activities (waste).
      価値の流れの創造: プロセス全体の流れを可視化し、非付加価値活動(ムダ)を特定して排除する。
    • Continuous Flow: Designing processes to minimize interruptions and delays, enabling smooth and efficient workflow.
    • Pull Systems: Producing goods or services based on actual customer demand rather than forecasted demand reduces overproduction.
      直前の価値の引き出し: 予測された需要ではなく、実際の顧客の需要に基づいて商品やサービスを生産することで、過剰生産を減らす。
    • Continuous Improvement: Encouraging a culture of ongoing improvement to drive incremental enhancements and innovations.
      継続的改善: 漸進的な強化や革新を推進するために、継続的な改善の文化を奨励する。
