What is the difference between Quality control, quality assurance and total quality management?

Why do companies use quality control or total quality management?
-
Answer:
Quality Control = think of a quality inspector at the end of the line looking for defects. Quality Assurance = Think of controls put into the process to prevent a defect. TQM = Think of the entire business system working to prevent defects in every stage of development. Companies use QC when they have poor QA or TQM. In a perfect world, if TQM was properly utilyzed, you wouldn't need QC.

I'm currently a student working in a quality assurance lab. From what i've seen, quality assurance is ensuring the product is within specifications, implementing procedures, etc. This is usually done on the supplier end. If you are someone who assembles TVs, DVDs, etc, you will have a quality control department. They will just audit the products to see if they are what they're supposed to be. They do not put into place any procedures, or take any active steps to improve their final product. They mainly audit, and talk to supplier if they notice any issues. TQM is the whole company looking to make the process better to deliver better products to the customer.

QC is when its been made(pass / fail), QA is putting procedures in place to prevent errors and TQM is taking a holistic view of all factors in producing an end result. I think any way........Its been a long time!

Quality control: a plan with the goal of ensuring that the product/service made and/or rendered, is at the highest ethical and profit making standards the company has in mind. Quality assurance: the steps taken to assure that quality control happens as above. Sometimes this is given in the form of a gurantee to the consumer. Total quality manangement: see above; insert slot A into slot B! Somebody gets this title and a big salary to be responsible for when these things do/don't happen! Companies use these measures for one reason only: TO MAKE A PROFIT! I think I explained this well enough to be the president of total quality management. Are you hiring?
