Manufacturing capabilities critical inputs

Determine manufacturing and supplier capabilities to control the critical input variables. 

It does not consider manufacturing capability in setting operating windows for the critical inputs. The resulting design may not be manufacturable. 

When obtaining estimates of the variation of the critical inputs, it is important to capture the full range of variation expected over long-term manufacturing. Table 8 summarizes the capabilities of the different critical inputs. 

Real-time monitoring fails, however, when the process tooling fails to monitor itself. If the process engineer determines that monitoring of an input parameter is critical but the tooling lacks a sensor to measure that parameter, then regardless of the capability of data acquisition software, the parameter cannot be monitored. To catch excursions at the earliest opportunity, it is critical for the tool manufacturers to build a self-monitoring process in the tool.
