Using T2 Chart to Monitor the Quality of Ash Content in Flour Production

The quality of goods and services can be improved if data sets are collected to determine the causes of variation. In this consideration, the data sets will enable the analyst to evaluate the stability of the manufacturing process. However, the purpose of applying any control chart is to identify the occurrence of special causes of variation that emanate from external source of the normal process. Although, the vital aspect of variations is that it reveals the strength and weakness of the process thereby providing means of improving the system. This also provides opportunity to repair and adjust the system due to special causes, though if such exist. In this discussion, the x bar chart and the T2 chart are applied to investigate the quality of ash content in flour production. The analysis is based on the data set obtained revealed that the two procedures showed that the ash content used in producing the flour is stable otherwise the process is in control.
