Quality Cost Trade-offs

Some suggest that there is a trade off between Conformity Costs (prevention and appraisal) and Non-Conformity Costs (internal failure and external failure): slashing costs in one area lead to an increase in costs in another area. Do you believe this is true? Do you think the trade off is $1 - to - $1; or is a dollar spent in one area more advantageous than in other areas, when evaluating quality? If some areas of quality spending are more advantageous, describe some unique types of significant consequence from quality cost cutting, or the significant growth from increasing quality spending.
