Question 2

ISO9000 Quality Audit

The following incident occurred during a third party audit of a producer of computer monitor. It contains situations for which non-conformity reports may be required. Examine the incident carefully and reference it with the BS EN ISO9001:2000 standard. Answer the questions and then fill in a non-conformity report when you think necessary.

In the storehouse, the auditor notices a box containing seven CRT tubes each with two labels attached; REJECT & URGENT. The Chief Inspector explains that this is part of a purchase order from a new supplier,‘twelve items were supplied three weeks late and when inspected these seven were found not to conform to the specification’. The auditor asks what happened to the other five CRTs. The Chief Inspector states that because the contract was urgent, five were released to production before the inspection could take place. In the production department, the Floor Manager explains that the five CRTs have been used to complete export orders. There is no record of which order used the suspected CRTs. In the Purchasing Department, the auditor asks how the new supplier of CRTs was selected. The purchasing clerk explains that the regular suppliers could not meet the delivery date and the order was placed with a new supplier because the price was extremely low. The clerk states that it was not a normal practice to consult or advise any other department in cases like this one.

Fill in the following non-compliance report if needed:
