4 Quality Cost:
Preventing, detecting and dealing with defects cause costs that are called quality costs or costs of quality. Quality
costs can be broken down into four broad groups.
1 Prevention Costs: This is the cost of anything you do to prevent quality error or to maintain the consistency
of quality .it begins with the orientation and training that you provide to new employees. It can include some
part of cost of parching equipment of maintained of designing, planning and ingraining.
2 Appraisal Costs: These costs begin with the inspection of purchased goods and materials. The cost of
inspection through the work process and finished goods is included related documentation and record
keeping as well as the calibration of test equipment and laboratory changes add to these costs. This
category also includes surveying customer satisfaction levels especially in-service companies.
3 Internal Failure Costs: These are the costs that occur when a quality defect is detected before it reaches
the customer. Most directly they include scrap and network costs. But the cost of re inspection of idle time
because of quality failure, and the related administrative costs, would also be included.
4 External Failure Costs: These are all the related to quality defects that reach the customer. Some are
direct returns warranty and replacement costs. Field repairs the cost of responding to complaints. Others
are indirect roles cost because of dissatisfied customer.
Associated with statistical sampling of apparels, acceptance quality level (AQL) is the “minimal standard for a
satisfactory process or product average”. Acceptance Quality Level (AQL) refers to the maximum number of
defective items that could be considered accepted during the random sampling of and inspection. The defects
that are found during inspection are classified into 3 categories:
• Critical: Must be 100% accurate. There is no range.
• Major: Normally 2.5%

• Minor: Normally 4%
