Suatu peralatan yang penting dalam kawalan mutu ialah carta kawalan Shewhart. Kelemahan carta kawalan Shewhart adalah ia hanya dikhaskan untuk pengeluaran bervolum tinggi. Walau bagaimanapun, sejak kebelakangan m1, wujud kecenderungan di kalangan pengeluar untuk menghasilkan lot bersaiz kecil atau pengeluaran bervolum rendah. Kecenderungan ini disebabkan teknik tepat pada masa, pengeluaran serentak, penyediaan kerja kedaian, pengurangan inventori dalam proses dan nilai kos yang semakin dititikberatkan. An important tool in quality control is the Shewhart control chart. The disadvantage of a Shewhart control chart is that it is only used for high volume manufacturing. However, in recent years, there exist a trend among manufacturers to produce smaller lot sizes or low volume manufacturing. This trend is due to just-in-time techniques (JIT), synchronous productions, job-shop settings and the reduction of inprocess inventories and costs.
