2. MES: Short for Manufacturing Execution System.
3. SFDC: The SFDC (Shop Floor Data Collection) System is the main software/hardware system used by 42Q for production control and the collection of manufacturing data.
4. Exception: SPC considers some out-of-control a valid group, meaning that the group is based on the rules that users selected when configuring monitor parameters.
5. Valid group: It means the data that is in the normal scope. On SPC control charts, a valid group of data points is plotted between the UCL and LCL.
6. DPMO: Short for Defects Per Million of Opportunities.
