    Study Notes

    What is Lean?

    • Lean is a team-based form of continuous improvement that focuses on identifying and eliminating waste.
    • Waste is non-value-added activity from the customer's viewpoint.
    • Lean should be thought of as a long-term health program for business, not a crash diet.

    Lean Failure

    • Over half of Lean initiatives have failed.
    • The primary reason for this is the lack of the proper culture to support the major changes required.
    • Management may not be willing to give up some control to workers, dedicate resource time, or spend money for training and improvements.
    • Lean is sometimes viewed as a “fad” that will go away or a short-term program.

    Implementing Lean

    • Lean requires both a top-down management commitment to change and a bottom-up participation and ideas.
    • The culture has to encourage and create a team-based continuous improvement mentality.
    • An effective way to implement Lean is through a train-do method, where the trainer or consultant teaches employees the basic concepts and tools.
    • Lean began to be applied to the manufacturing industry (Lean Manufacturing), the office for administrative processes (Lean Office), and recently to the supply chain and logistics function (Lean Enterprise).

    Supply Chain and Logistics Management

    • Supply chain management encompasses the planning and management of all activities involved in sourcing, procurement, conversion, and logistics management.
    • The Supply Chain Operations Reference (SCOR) Model divides the supply chain into five management processes:
      • Plan: Balancing supply and demand.
      • Source: Procurement of goods to meet demand.
      • Make: Transformation process, taking raw materials and converting them into finished products.
      • Deliver: Resources to move materials along the supply chain.
      • Return: Reverse logistics process for product or material that is returned.

    Why All the Interest in Lean Supply Chain Management?

    • The first reason is financial: the supply chain is a major cost center, ranging from 50 to 80 percent of the cost of sales.
    • Reducing costs by a relatively small percentage can have the equivalent contribution to profit of increasing sales by a much larger percentage.
    • The second reason is operational: the bullwhip effect describes the magnified effect that occurs when orders move up the supply chain.
    • Increased use of outsourcing, global supply chains, e-commerce, and shorter product life cycles has added pressure on the supply chain to be efficient while it has become stretched and more complex at the same time.

    The Eight Wastes

    • Waste: anything that does not add value to a process.
    • The eight wastes are applicable to any process, whether it is manufacturing, administration, or transportation.
    • The eight wastes are:
      1. Inventory Waste
      2. Transportation or Movement Waste
      3. Motion Waste
      4. Waiting Waste
      5. Overproduction Waste
      6. Overprocessing Waste
      7. Defect or Error Waste
      8. Behavioral Waste (Underutilized Employees)### The Eight Wastes
    • The Eight Wastes are categorizations of excess movement or actions in a process that do not add value to the product or service.

    Transportation Waste

    • Transportation Waste occurs when materials are moved unnecessarily, affecting inventory accuracy and increasing the risk of damage or loss.
    • Companies pay for each move, and the material may be moved to a different location, increasing the risk of losing it and accidentally ordering more.

    Motion Waste

    • Motion Waste refers to any motion that does not add value to the product or service.
    • The concept of motion waste is about having frequently used items closer and less frequently used items further away and higher up.
    • Point-of-use storage means having just enough material or information nearby, which can be replenished when needed from further away.
    • Ergonomics is important in motion waste, considering not only efficiency but also safety.

    Waiting Waste

    • Waiting Waste is time spent waiting on materials, supplies, information, or people needed to finish a task.
    • This waste can occur in various environments, including the shop floor, warehouse, or office.
    • A significant part of a product's or service's lead time is spent waiting, often due to long setup times, large batch sizes, and downtime.
    • Examples of waiting waste include waiting for equipment to start up, computer breakdown, signatures, or employees on different work schedules.

    Overproduction Waste

    • Overproduction Waste occurs when manufacturing, ordering, or processing something before it is actually needed.
    • This typically results in an excess of major waste.

    Defect or Error Waste

    • In manufacturing, defect waste refers to repairing, reworking, or scrapping materials due to errors.
    • The further along a defect gets, the more costly it is to the company.
    • In the office and warehouse, defect waste can include errors made during data entry, receiving, and picking and shipping the wrong product.
    • Causes of defect waste include poor processes, too much variation, supply issues, insufficient or improper training, and tools and equipment not properly calibrated or precise.

    Behavioral Waste

    • Companies need employee creativity and participation to eliminate the other seven wastes.
    • Behavioral waste is closely related to the elimination of the other seven wastes.
