How Do You Create A Control Chart?
A control chart is a tool used for statistical process control (SPC) in manufacturing operations. The chart graphically displays process stability by plotting the occurrence of defined events or specific values or measurements. Upper and lower control limits are made visible to show when plotted data for an event or value falls outside the predicted norm. Control charts are used to monitor process effectiveness, to assess the impact of any changes made to how the process operates and to identify opportunities for improvement or events requiring corrective action. Collect information to identify the data to be recorded. Attributes data is recorded as a count of occurrences. An example of attributes data could be the number of parts exhibiting a specific characteristic defect produced during a specific time frame. Variables data is recorded by a value, such as temperature readings recorded at set intervals while the process is in operation. Collect information to set upper and lower cont
