Control charts are used to see the performance of a process. Nonparametric control charts are present to overcome processes with unknown distribution patterns. This paper will show the application of nonparametric control charts using the Sign Test and Wilcoxon Sign Rank Test on the Animal Feed data of PT. Japfa Comfeed Indonesia, Tbk. The results show that the Wilcoxon Sign Rank control chart has the same effectiveness as the sign control chart.
