7.4 Purchasing
7.4.1 Purchasing Process
7.4.2 Purchasing Information
7.4.3 Verification of Purchased Product
7.3.6 Design and Development Validation
7.3.7 Control of Design and Development Changes:
Upon receiving the first prototypes, a series of evaluation, validation, characterization and qualification
tests will be performed to ensure adherence of the product to the target specifications. If all of the test
results are satisfactory, the product will move to the release stage.
Design and development changes to the existing products are reviewed, verified, validated and
approved as defined in the applicable procedures. The Qualification Review Board is responsible to
evaluate the changes and to inform applicable Customers when there is a major change to a released
product. The results of the design activities are documented in various technical documents, drawings,
specifications, notes and computer files which reflect the requirements for implementation of the design
changes into a functional product. Copies of certain documents are filed in the design binder which
resides with the respective design group. Copies of relevant documents are filed in the product binder
which resides with manufacturing. Computer files are archived and backed-up from the engineering
computer network. The results of design verification, such as document review or qualification testing,
are recorded and retained by the respective design department. Design of Exar integrated circuits is not
regulated by any regulatory body such as UL/CSA, FDA, OSHA, etc. When applicable standards are
revised, Exar receives the latest revision for review and internal distribution as applicable.
Purchasing is responsible for key supplier relations, negotiations with suppliers, obtaining quotations
and issuing the purchase documents. Purchasing, together with the Supplier Management Team, is
responsible for initiating the supplier selection process. Purchasing ensures order acknowledgment and
is responsible for monitoring the processing of the order to ensure that Exar purchased products
comply with the specified requirements. Purchasing is also responsible for maintaining an approved
supplier list.
Purchasing documents are required to contain a clear description of the products ordered and the
requirements the product has to meet. To the extent appropriate for the product or the service, the
following forms a part of the purchase documents:
The Supplier Management Team, chaired by the Sr. Purchasing Director, is comprised of
representatives of Manufacturing, Foundry, Assembly and Test Engineering, R&QA and Production
Control. The team is responsible for developing a supplier management program, supplier selection,
and the preparation of score cards reflecting key supplier performance. A quarterly supplier rating is
prepared to assess key supplier performance. Purchasing shall arrange a quarterly business review
with key suppliers.
Should Exar, Exar’s Customer or Exar’s Customer representative decide to perform source inspection
at the supplier’s facility, the source arrangements and method of product acceptance shall be
incorporated into the purchase order. This verification would not absolve the supplier of the
responsibility to provide acceptable product nor would it preclude subsequent rejection.
