Meaning
Industrial losses defined by a persistent decline in the ratio of finished goods to raw material inputs indicate a loss of efficiency. Monitoring yield erosion identifies waste before it destroys profitability.
Regular Monitoring
Regular monitoring of the production line reveals subtle failures in machinery or labor practices that might not be visible during a single shift. Small increases in yield erosion often indicate that a manufacturing system is nearing the end of its maintenance cycle. These deviations lead to a higher percentage of scrapped items over a month of operation.
The Cost
The cost of yield erosion is measured by the lost value of wasted materials and the overhead spent on defective units. When a pilot run demonstrates a high success rate but the production yield drops during scaling, the business case for the product may become invalid. Predicting these losses is a requirement for setting accurate pricing and delivery schedules.
Quality Audit
Regular audits of the scrap bin and the rework station are necessary to identify the root causes of the loss. If the rate of yield erosion exceeds the threshold set during the design phase, the entire process might require a reset or a redesign. Maintaining a consistent output rate ensures that the company can meet its volume commitments to customers.
