8.4.1 General
The purchasing process is essential to Harrington Signal Inc.’s ability to provide our customers with products that meet their requirements. Harrington Signal Inc. ensures that purchased product conforms to specified purchase requirements. Harrington Signal Inc. accomplishes this by controlling our supplier base and inspecting purchased product as required. Obviously, the type and extent of control applied to the supplier and the purchased product shall be dependent upon the effect of the purchased product on subsequent product realization or the final product.
It is the responsibility of the Purchasing Manager and the Purchasing Department to evaluate and select suppliers based on their ability to supply product in accordance with specified requirements. Manufacturing may be called on to assist as required. Criteria for selection, evaluation and re-evaluation are defined in the Externally Provider Evaluation procedure.
8.4.2 Type and extent of control
Purchased items and materials are verified for correctness by the Receiving Department. If additional inspection is required, it is noted on the purchase order and the item is sent to Quality Inspection for further inspection.
Should Harrington Signal Inc. or any of our customers decide to perform verification at the supplier’s premises, the verification arrangements and method of product release shall be stated in the purchasing information.
8.4.3 Information for external providers
Harrington Signal Inc. uses purchase orders (PO’s) to describe the product to be purchased, including where appropriate:
-
- Requirements for approval of product, procedures, processes and equipment
- Requirements for qualification of personnel
- Quality management system requirements
- The Purchasing Department is responsible for ensuring the adequacy of specified purchase requirements before their communication to the supplier. Processes have been established for the external providers’ interactions with the organizations, control and monitoring of the external provider’s performance, and the verification or validation activities that the organization, or its customer, intends to perform at the external providers premises.
