In-depth Use Case / Real-world Example

A manufacturing company that assembles household appliances tracks Supplier Lead Time Variability to assess how often suppliers deviate from their promised delivery schedules. If a supplier consistently delivers components late or early, this metric will reflect the inconsistency. A low variability score means the supplier is predictable, reducing the risk of production delays. For example, if 90% of orders are delivered within the agreed timeframe, the variability score will be low, showing high reliability.
