• Supplier has a documented process to identify and regularly
update internal expectations, objectives, and requirements.
• Supplier has a documented process to translate internal and external
expectations, objectives, and requirements into QOS measurables.
• Supplier has a documented process to assign targets and objec-
tives to each QOS measurable.
• Supplier has a documented process to assign chosen measur-
ables to appropriate management levels for review, follow-up,
• Supplier utilizes action plans to drive statistically valid contin-
ual improvement of chosen metrics. These are tracked at QOS
• Supplier’s management team holds monthly QOS performance
review meetings with representatives from manufacturing, qual-
ity, engineering, and human resources. Improvement actions
are taken by cross-functional teams that include all levels of the
• QOS reviews include a review of all applicable customer’s and
supplier’s key process metrics.
• Metrics monitoring customer satisfaction that are related to sup-
plier manufacturing are understood and tracked.
• Failure mode and effect analysis (FMEA)/control plans
• All customer parts have documented design and process failure
mode and effects analysis (DFMEA, PFMEA), and design control
plans (or DCPs). There is a robust process in place for developing
• FMEAs are reviewed annually or as issues arise. A Pareto is used
to focus on (1) severity and (2) the product of severity and occur-
rence, and (3) to identify high RPNs in order to prioritize actions
to drive improvements. All error detection areas are reviewed
and, where feasible, plans exist to move to error prevention
devices (e.g., poke-yoke).
• Suppliers, in cooperation with their customers, have identied
critical characteristics (CCs), signicant characteristics (SCs), and
high-impact characteristics (HICs) on their PFMEAs and DCPs
for every customer part or family of customer parts.
• Supplier works with customer to establish nal agreement of SCs
and HICs. Suppliers obtain specic agreement from customer for
any parts not having SCs or HICs.
• Supplier ensures that all print dimensions and callout notes on
the engineering drawing are always met through DCPs, work
instructions, job setup instructions, and receiving inspection.
