How are key process input variables identified?
What are key process output variables? Key process output variables (sometimes referred to as Key Characteristics) are traits or features of a part, piece of material, assembly, subsystem, or system whose variation has a significant influence on fit, performance, reliability, manufacturability, or assembly. In short, they are characteristics that have a big impact on efficiency and/or customer satisfaction. Variation in key process output variables leads to lower levels of quality and reliability and, ultimately, higher costs. Examples of key process output variables are: – Slip torque of an actuator – Gap between car body and rear quarter glass panel – Cabin wind noise – Fill volume for a bottled beverage What are key process input variables? Key process input variables are process inputs that have a significant impact on the variation found in a key process output variable. That is, if the key process input variables were controlled (e.g. held constant), the process would produce pre
