83: Acceptance Criteria Issue
Definition/Typical Issues
Was there difficulty in understanding or implementing the acceptance criteria for raw materials and parts? Were the acceptance criteria ambiguous or unclear?
Note 1: This node only applies to raw materials and parts procured from outside your facility. Acceptance criteria for manufactured items (fabricated within your facility) are specified as part of the Product Control and Acceptance Issue (#87-93) section.
Examples
Example 1
- Acceptance criteria specified that the bolts should have a Rockwell-C hardness of 30. Warehouse personnel did not know what this meant or how to determine whether the bolts met this specification. As a result, some bolts failed in service.
Example 2
- Acceptance criteria specified that the powder should not contain excessive moisture. Warehouse personnel did not know exactly what this meant. As a result, they accepted material that was unusable.
Example 3
- Acceptance criteria had not been developed for rubber gaskets used in a process. The gaskets deteriorate rapidly if they are not individually sealed in plastic. Without any acceptance criteria, the warehouse accepted a shipment of gaskets that were not individually wrapped and sealed.
Typical Recommendations
- Have the warehouse personnel assist in the development of the acceptance criteria to ensure that the criteria are clearly understood by those who will use them.
- Develop specifications for critical repair parts and maintenance materials.
- Ensure that vendors supply parts and materials that conform to specifications.
