quality control (QC)

Quality control (QC) is a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer. 

QC is similar to, but not identical with, quality assurance (QA). QA is defined as a procedure or set of procedures intended to ensure that a product or service under development (before work is complete, as opposed to afterwards) meets specified requirements. QA is sometimes expressed together with QC as a single expression, quality assurance and control (QA/QC).

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, corrective action must be decided upon and taken (for example, defective units must be repaired or rejected and poor service repeated at no charge until 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.

I'd like to see Microsoft's QC procedures. I feel if it were better, there would be less patches.

QA includes prevention of quality problems through planned and systematic activities where as QC includes activities or techniques used to achieve and maintain the product quality, process and service.

What is meant by Quality Control?

Quality Control refers to the checks carried out on a product by workers, during stages of its manufacture. These checks may include, simply ensuring that components are positioned correctly, or that they are the correct type and size. A final quality check should include, testing the product to ensure it is to the correct standard, before it is distributed to the retailer / customer. A combination of visual checks and automated checks (by sensors and computers) are usually carried out.

Example: A guitar is manufactured for a customer. Many stages are involved in the making of the guitar. Four of the stages of manufacture are seen below. Each of the stages includes a quality check, to ensure that substandard components are rejected and that only accurately made components are assembled, to form the final guitar.

Hi... What is the quality control in higher education? I need this to Write proposal (PhD).
Cancel
I would guess for QC in higher education; take a look at the course itself. Is the material current or outdated for one. No sense learning material no longer in use. Then look at the pass / fail rate of the students. This can help determine if the material was presented in a clear and understandable way. If it was not presented well that may be the cause for failure.. The last thing would be support. If a student has questions is there help available from knowledgeable staff or other resources?

What items do I mention on this subject? What I focus on is even convincing my supervisor to accept my proposal?
