第3题：

(b) The management of Division C has identified the need to achieve cost savings in order to become more

competitive. They have decided that an analysis and investigation of quality costs into four sub-categories will

provide a focus for performance measurement and improvement.

Required:

Identify the FOUR sub-categories into which quality costs can be analysed and provide examples (which

must relate to Division C) of each of the four sub-categories of quality cost that can be investigated in order

that overall cost savings might be achieved and hence the performance improved. (8 marks)

正确答案：
(b) Quality costs may be monitored by measuring costs of non-conformance and costs of conformance.
Costs of non-conformance occur when the product fails to reach the design quality standards. Such costs may be subdivided
into internal failure costs and external failure costs.
Internal failure costs occur when the failure is detected before the transfer of the product to the customer.
External failure costs occur when the failure to reach the required standards is not detected until after the product has been
transferred to the customer.
Costs of conformance are those incurred in reducing or eliminating the costs of non-conformance. Such costs may be
subdivided into appraisal costs and prevention costs.
Appraisal costs are those associated with the evaluation of items such as purchased material and services in order to ensure
that they conform. to the agreed specification.
Prevention costs are those associated with the implementation of a quality improvement programme. Such costs are planned
in advance and their implementation should lead to continuous improvement.
Examples of quality costs relevant to Division C may include:
Internal failure costs: cost of materials scrapped due to poor receipt and storage procedures or losses of CC output due to poor
processing routines.
External failure costs: cost of quality problems with batch of CC not detected until it has reached Division B. This may require
free replacement of the batch and compensation for loss of output by Division B.
Appraisal costs: evaluation of purchased material and services in relation to the manufacture of CC to ensure that it conforms
to the agreed specification; e.g. inspection and testing before use.
Prevention costs: the cost of implementation of staff training and the costs of equipment testing to ensure that it conforms to
the specification standards required for the production of CC.
(Alternative relevant examples would be accepted)
