This work focuses on finding a balance between the requirements to maintain product initial failure rate and the need to improve business objectives. We build on quality function deployment (QFD) by developing an innovative methodology for reducing testing in the transition from development to production. The methodology allows the number of tests to be reduced, without increasing the risk of lowering product quality. Our methodology assumes that testing affects product initial failure rate and business objectives simultaneously. Hence, a QFD‐based methodology comprising two matrices is developed. Matrix 1 translates the desired improvement in the business objectives into the relative importance of the various test types. Matrix 2 translates the product failure improvement needs into the relative importance of the various test types. We implement the methodology in a company developing and manufacturing medical devices. We find that the events “vital tests concerning the business objectives” and “vital tests concerning the failures in products” are mutually exclusive. Hence, we can conclude that it is possible to achieve a significant reduction in the number of tests conducted on the medical devices. The results show that the tests that can be reduced are those that will not affect product initial failure rate but that do have a significant impact on business objectives.

通过减少从开发到生产的过渡过程中的测试来提高业务目标

这项工作的重点是在维持产品初始故障率的需求与改善业务目标的需求之间找到平衡。我们通过开发创新的方法以减少从开发到生产的过渡过程中的测试，从而在质量功能部署（QFD）的基础上进行开发。该方法可以减少测试次数，而不会增加降低产品质量的风险。我们的方法假设测试会同时影响产品的初始故障率和业务目标。因此，开发了包括两个矩阵的基于QFD的方法。矩阵1将所需的业务目标改进转化为各种测试类型的相对重要性。矩阵2将产品故障改进需求转化为各种测试类型的相对重要性。我们在开发和制造医疗设备的公司中实施该方法。我们发现“关于业务目标的重要测试”和“关于产品故障的重要测试”事件是相互排斥的。因此，我们可以得出结论，可以大大减少在医疗设备上进行的测试数量。结果表明，可以减少的测试是那些不会影响产品初始故障率但确实会对业务目标产生重大影响的测试。我们可以得出结论，可以大大减少在医疗设备上进行的测试数量。结果表明，可以减少的测试是那些不会影响产品初始故障率但确实会对业务目标产生重大影响的测试。我们可以得出结论，可以大大减少在医疗设备上进行的测试数量。结果表明，可以减少的测试是那些不会影响产品初始故障率但确实会对业务目标产生重大影响的测试。
