Prioritizing Processes and Selecting Parameters for Control Charts Implementation
Abstract:In a manufacturing process where there are many parameters need to be controlled, many practitioners found that the implementation of control charts to these parameters simultaneously are difficult or sometime infeasible especially when resources for control activities are limited. In order to use the resource effectively and ensure that these parameters are controlled as per priority, this article presents a guideline to prioritize processes and select parameters for control charts implementation. There are four steps proposed in the guideline, which are step 1: prioritize importance values of final product parameters, step 2: prioritize processes to control based on the relationship between processes and the final product parameters, step 3: determine the relationship between process parameters, in-process product parameters, and the final product parameters for the selected processes, and step 4: select parameters to control. The guideline focuses on the progression of process control from the final product parameters control at downstream processes to process parameters control at upstream processes in order to enhance process control responsiveness.
