Inspection cycles are how often a product or service is inspected to determine its defect rate or quality level. These inspection cycles are determined by contractual requirements, quality standards organizations, or a cost benefit analysis of how much it costs to sample and test as compared to the cost / benefit analysis of a defect getting through. How do you know when to increase inspection cycles? |

Step 1 If a large number of defective product was released. Step 2 If a known and dangerous defect was identified. Step 3 If a potentially dangerous defect was identified. Step 4 If a defect with a high cost of repair or rework is identified and its occurrence rate is unknown. Step 5 If a new defect is identified and its occurrence rate is unknown. Step 6 If customer satisfaction surveys include product quality as one of the top 3 complaints. Step 7 If the quality standards organization to which adhere has mandated a tighter quality inspection cycle. Step 8 If the quality standards organization to which adhere has mandated a higher quality level, and a tighter inspection cycle will prove that your product meets those standards. Step 9 If a new supplier is used for a component, which has an unknown quality level. Step 10 If the customer requires it in a new contract. Step 11 If completed product has increased in variability, and more inspections more often will determine if the new variability is still within specification or will create outliers outside of the required process control limits. |
