In order to implement an effective QC program, an enterprise must first decide which specific standards the product or service
must meet.Then the extent of QC actions must be determined (for example, the percentage of units to be tested from each lot).

Next, real-world data must be collected (for example, the percentage of units that fail) and the results reported to management
personnel. 

After this, correctiveaction must be decided upon and taken (for example,defective units must be repaired or rejected and poor 

service repeated at no chargeuntil the customer is satisfied). If too many unit failures or instances of poor service occur,
A plan must be devised to improve the production or service process and then that plan must be put into action. 

Finally, the QC process must be ongoing to ensure that remedial efforts, if required, have produced satisfactory results and to 

immediately detect recurrences or new instances of trouble.
