To identify what tolerances and processes to control, many organizations are using a Key Characteristics method (KCs) [Thornton, 1999]. KC methods are used by design to identify and communicate to manufacturing where excess variation will most significantly affect product quality. Most KCs approaches are based on the concept of a KC flowdown. The KC flowdown prides a system view of potential variation risk factors and captures designers and manufacturers knowledge about variation and its contributors. A hierarchical tree structure is commonly used to describe the Key Characteristics of a product [Thornton, 1999]. A KC flowdown allows for a decomposition of the product into essential features and processes – enabling traceability of cause and effect. Figure 6 shows a KC flowdown. Product level KCs are identified at the highest level of the flowdown and are product...
