Lean Foundations and Principles

Glossary of Lean Foundations and Principles

  • Flow

    • A Lean principle that ensures value-creating steps move smoothly without interruptions or delays, creating a continuous and efficient process.

  • Just-in-Time

    • A Lean production method that ensures goods are produced or received only when needed, reducing inventory and increasing flexibility.

  • Kaizen

    • A Japanese term meaning 'continuous improvement'; it involves everyone in the organization identifying and implementing small, incremental changes to improve processes.

  • Kanban

    • A visual work-management method that uses boards and cards to represent tasks and workflow stages, helping teams manage flow and avoid overload.

  • Lean

    • A methodology focused on maximizing customer value while minimizing waste, originally developed in manufacturing and now applied across various industries.

  • Non-value-added

    • Activities that consume resources but do not add value from the customer's perspective and should be minimized or eliminated.

  • Perfection

    • The Lean principle of continuously refining processes to reduce waste and increase value, striving for an ideal state of performance.

  • Poka-Yoke

    • A Japanese term meaning 'mistake-proofing'; it refers to designing processes or products to prevent errors before they occur.

  • Pull

    • A Lean principle where work is initiated based on actual demand rather than forecasts, ensuring resources are used efficiently.

  • TIMWOODS

    • An acronym representing the eight types of waste in Lean:

    • Transportation

    • Inventory

    • Motion

    • Waiting

    • Overproduction

    • Overprocessing

    • Defects

    • Skills

  • Three-point test

    • A Lean method to determine if an activity adds value by asking:

    1. Does it meet a customer’s need?

    2. Does it change the product or service?

    3. Is it done right the first time?

  • Value stream mapping

    • A Lean tool that provides a visual overview of all steps in a process, helping identify inefficiencies and opportunities for improvement.

  • Value-added

    • Activities that directly contribute to the product or service, meet customer needs, and are done right the first time.
