Here are the type of
costs that cannot be reduced as a result of better quality in the
manufacturing process -
Cost of
quality - COQ is the main method that allows the
organisation to determine the resources that need to be used to
prevent poor quality.
- Appraisal costs cannot be reduced as these happen to make sure
that level of quality is maintained.
 
- The internal failure costs which are directly related to
defects founds before customer services the products or services
are other costs that cannot be reduced.
 
- External failure costs which occur post the customer receives
the products and services cant be compromised as well.
 
Other cost areas that
cannot be reduced include -
- To make sure quality is maintained the prevention costs,
appraisal costs cant be reduced.
 
- The cost that is directly related to design, implementation
& maintenance of quality systems cannot be reduced.
 
- The costs associated with quality planning and making sure
operations and tools are used accordingly.
 
- The costs associated with inspection and control.
 
- The costs associated with training, development, preparation
& overall maintenance of training programs.
 
Overall the cost to maintain the quality levels, the
technology, the cost to keep servicing the customers, cost of using
the right machinery and proocess etc are the areas which cannot be
reduced.
