80: Material/Parts Issue
Definition/Typical Issues
Was the error the result of inadequate control of changes to procurement specifications or purchase orders for raw materials or parts? Did product acceptance requirements fail to match design requirements or were they otherwise unacceptable?
Note 1: This section (nodes #80-86) only applies to raw materials and parts received from outside the facility or organization, whereas the Product Control and Acceptance Issue (#87-#93) section applies to products manufactured within the facility or organization.
Examples
Example 1
- A large tank was fabricated using an incorrect grade of stainless steel because the buyer made an unauthorized change to the purchase order and the personnel who signed off on the order did not detect the change.
Example 2
- A contract to purchase logs from a supplier did not include late delivery penalties. As a result, the supplier was routinely a week or two behind schedule.
Typical Recommendations
- Procurement specifications should not be changed without review and approval by knowledgeable personnel.
- Ensure that acceptance requirements are documented and match the design requirements.
- Ensure that tests address all acceptance criteria.
- For products with a shelf life, develop a system to document the product's date of manufacture and date of distribution.
- Monitor inventory levels and restock in a timely manner.
