charts Used for monitoring the mean and range of a process c charts Track the number of defects in a sample p charts Monitor the proportion of defective items in a sample 2 Process Capability Process capability analysis evaluates a processs ability to consistently produce outputs within predefined specifications This analysis helps businesses assess the effectiveness of their control procedures and identify areas for improvement Key metrics used in process capability include 3 Cp The process capability index which measures the potential capability of a process Cpk The lower of the two Cp indices indicating the capability of the process to meet the lower or upper specification limit 3 Acceptance Sampling Acceptance sampling involves inspecting a representative sample of products to determine the quality of an entire lot This method helps businesses decide whether to accept or reject a shipment based on the quality of the sample Key types of acceptance sampling plans include
