    Study Notes

    Value Stream Mapping (VSM)

    • A value stream is the flow of information, materials, or ideas throughout an entire enterprise, starting and ending with the customer.
    • It depicts demand and the enterprise's fulfillment of that demand.
    • It identifies value-added and non-value-added steps in the entire supply chain.
    • It pinpoints critical processes (constraints).
    • It measures performance at each step.

    What Flows Through a Value Stream?

    • Items flow through value streams.
      • In manufacturing, materials are items.
      • In design and development, designs are items.
      • In service, external customer needs are items.
      • In administration, internal customer needs are items.
    • Customers are both internal and external.

    Measuring Value Stream Processes

    • Each process/activity should be measured to understand its impact and improvement potential.
    • Examples of measurements include:
      • Step duration
      • Setup time
      • Accuracy
      • Yield
      • Resources required
      • Installation time
      • Energy consumption

    Examples of Measurable Metrics

    • Time to setup
    • Time to pack one item
    • Yield percentage
    • Waste (kilograms)
    • Packing product

    Mapping and Improving a Process

    • Decide which process to map.
    • Form a multi-disciplinary team.
    • Start at the end of the process and work backward.
    • Walk the process with the process owner.
    • Collect process information and metrics.
    • Use post-it notes to record each step and its metrics.
    • Identify problem areas and areas for improvement.
    • Use Lean tools to design an improved future state.
    • Improve the process, verify it works, and redraw the map.

    Current vs. Future State Maps

    • VSMs illustrate current and future states of a process.
    • Current-state maps depict the existing process.
    • Future-state maps highlight improvements.

    Typical VSM Examples

    • Examples of value stream maps are provided for food manufacturing and pharmaceutical manufacturing.
