monitors their performance on an ongoing basis.
When warranted by poor quality performance, supplier corrective is requested and verified
for effectiveness.

performed if warranted. Otherwise new suppliers are put on a limited approval status and
their performance closely monitored through the initial shipments.
Customer approved sources are used for any special hardware requiring the use of special
processes.
Where the customer has not specified the use of their approved sources, NADCAP special
process certification is recognized.

From the bill of material, Production Control issues requisitions for procurement of raw
material and components and routes them to Quality Assurance.

requirements for the purchase order, including certifications, test data, source inspection,
control of age sensitive items, and use of customer approved sources.

approval and verification of placement with an approved source.

materials to prevent recurring defects. Lean Manufacturing activities improve quality and
delivery while reducing costs.

The nature of the product designed and manufactured by Arrowhead Products has not
justified establishment of a separate product support department, and support is provided
directly by the engineering department.
Typically, most support issues and necessary modifications to a system are resolved
during the design and development phase of a program. The company recognizes that
engineering capability is a core competency, and critical to customer satisfaction. As
such, the stability and longevity of the engineering department is highly valued and
Arrowhead has established an excellent record in this regard.
As a result, the familiarity with customer and system requirements established during the
design and development phase of a project is maintained throughout the life of the
program.
