    is allied with the quality of a product. It is the sum
    total of costs which is incurred while maintaining
    quality up to standard levels plus the cost of
    failure to maintain that level. Cost of Quality will
    not incur if the quality is free from faults.

    creating a quality product or service.

     minimal level is by building the quality as part of
     the processes.
