Selection Strategy
Quality control frameworks allow for the acceptance of certain production batches without physical examination based on the performance of previous lots. In textile manufacturing, skip lot testing is a statistical sampling plan where only a fraction of the submitted lots are selected for lab analysis. This method is applied when a process is proven to be in a state of statistical control and the risk of a defect is extremely low.
A Logic
Random number generators determine which batches will be inspected and which will be passed automatically. This maintains a level of unpredictability that ensures the factory does not relax its own internal quality controls.
Selection Strategy
Only non-critical properties or gold-rated suppliers are eligible for this type of reduced oversight. High risk items are never eligible for this type of plan. The strategy must be documented in the quality agreement and approved by the compliance department.
Operational Savings
Reducing the number of tests performed lowers the annual laboratory spend and speeds up the supply chain. It allows for a more efficient use of manpower at the warehouse. Skip lot testing serves as a reward for manufacturers who invest in their own quality management systems.
