QC is not a function of any single department or a person. It is the
primary responsibility of any supervisor to turn out work of acceptable
quality.
1. Off-line quality control
2. Statistical process control
3. Acceptance sampling plans.
1. Off-line quality control:
Its procedure deal with measures to select and choose controllable product and process parameters in such a way that the deviation between the product or process output and the standard will be minimized.
Much of this task is accomplished through product and process design.
Example:Taguchi method,principles of experimental design etc.
2.Statistical process control:
SPC involves comparing the output of a process or a service with a standard and taking remedial actions in case of a discrepancy between the two.
It also involves determining whether a process can produce a product that meets desired specification or requirements. On-line SPC means that information is gathered about the product,process,or service while it is functional.
The corrective action is taken in that operational phase. This is real-time basis.
3.Acceptance sampling plans:
A plan that determines the number of items to sample and the acceptance criteria of the lot,based on meeting certain stipulated conditions (such as the risk of rejecting a good lot or accepting a bad lot) is known as an acceptance sampling plan.
