Critical to Customer (CTC) - definition(s)

Critical to Customer - CTC - This is the input to the Quality Function Deployment activity, for the customer requirements side of the analysis. Not same as CTQ.

CTQ's are the internal critical quality parameters that RELATE to these customer-critical parameters. QFD relates the two, and leads to the DFMEA efforts which quantify the severity and frequency of occurance of failure to meet the CTQ's and thus the CTC's by relationship. Car door sound when closing might be a CTC, while the dimensional tolerances and cushioning that produce those conditions are CTQ's for the auto maker.
