Since the supplier is counting the number of blemishes on each silicone sheet, a c chart would be appropriate to monitor the number of defects in the manufacturing process over time. A c chart is used for count data and evaluates whether the process is in control or not by comparing the number of blemishes per sample to established control limits.
