A supplier of part used in a customer factorys operation does not meet the companys criteria to be excluded from acceptance sampling. As such, an appropriate sampling plan must be created that ensures good parts are delivered to the consuming production process while minimizing the cost of inspection. The supplied part has a single critical feature that must be assessed during inspection. This feature can be measured with an attribute inspection method and it can also be measured with a variable gauge in roughly the same time per part inspected. Both the attribute and variable measurement methods are considered to be highly reliable (i.e., attribute agreement analysis and gage R&R results are acceptable). Also, the equipment required for both measurement methods is considered to be available at a negligible cost. Which measurement method, attribute or variable, would you recommend? Why? Are there any assumptions you would need to validate first before finalizing your recommendation?
