TQM, QC and QA
TQM (Total Quality Management)
Involves the entire workforce, products are check at each stage of production. Not just left
until the end for the inspectors. TQM is a way of preventing poor quality, not just discarding
the defect products.
Advantages
1. Eliminates cost of inspection as it is workers who carry it all out.
2. Less wasteful than throwing out defective products as there are no defective products.
3. Puts the customer at the heart of the production process as quality is vital
4. Makes workers more motivated as they are making decisions and are more involved.
Disadvantages
1. Requires a strong leader ­ something that many businesses don't have. The process needs to
be constantly monitored and effective.
2. Needs a lot of money put in to train staff to perform it effectively.
3. It may become bureaucratic as leaders may get bossy. This will result in a lower staff morale.
4. Disruption and costs may outweigh benefits.
QC (Quality Control)

about inspecting rather than preventing.

Disadvantages
1. Leaving quality to the inspectors may mean that poor quality is built into the product.

products are thrown away.
3. It's often carried out at the end of the production process, when its too late.
QA (Quality Assurance)
The processes that ensure production quality meet the requirements of the customers. It
focuses on the quality of the production process itself.
Advantages
1. It makes sure the company has a quality system for every stage in the production process.
