| 1. Overview
of Quality Rating
| (back to Table of Contents)
Quality Ratings are generated for each
supplier site. Quality Ratings are calculated for every month. The monthly
Quality Ratings are combined using a 6 month weighted average formula to
produce an overall weighted average Quality Rating figure which is used by
Visteon for business decisions. On the third working day of a new month,
the Quality Rating for the preceding month is calculated for the first
time and the Quality ratings for the 12 months displayed are re-computed.
The Quality Rating has a maximum of 100 points. Points are awarded
for the supplier performance (PPM, Quality Rejects) and the Supplier's
Quality system (example ISO/TS 16949). Full details are given below.
Suppliers need to take actions to maximise their Quality Rating
score. Visteon uses a G-Y-R system for Quality Rating (weighted average
figure) as follows:-
| Green |
above 70
points |
| |
| Yellow |
50 to 69
points |
| |
| Red |
49 points and

Rating Components | (back to Table of Contents)
| 2.1 Quality
Rating Components - Overview
| (back to Table of Contents)
The Quality Rating is
composed of the following categories and points distribution:-
| 2.2 PPM
Performance - 25 Points
| (back to Table of Contents)
The PPM performance will
be based on current month's performance:
| PPM
Range |
Points
Awarded
|
| 0 PPM |
25 points |
| 1 to 25 PPM |
20 points |
| 26 to 60 PPM |
15 points |
| 61 to 120 PPM |
10 points |
| 121 to 250 PPM |
5 points |
| above 250 PPM |
0 points
|
| 2.3 Quality
Reject (QR) Performance - 25 points
| (back to Table of Contents)
QR performance will be based on
current month's instances
2.3.1 Types of Quality Rejects

2.3.2 Quality Reject:
Severity Code Point Deductions
(back to Table of Contents)
2.3.3 Formula for Quality Reject points calculated
monthly:
(back to Table of
Contents)
Points calculation is based upon PPM Quality Rejects
25 points - [(# H x 15 ) +
(# M x 10 ) + (# L x 5 ) + (# undefined x 5 )] ; Result = >
0
'# H' is the count of High severity QRs etc. The count is by QR reference
numbers, a Quality Reject with multiple part numbers counts as one.
| 2.4 Quality
System Status - 30 points
| (back to Table of Contents)
Points are assigned based
on the Quality System status at the supplier site. Point
values (up to a maximum of 30) are illustrated in the
following table:
The Quality System that receives the most points is displayed in the expanded Monthly Quality Rating section. If two or more Quality Systems are awarded the same number of point, or no points, the system with the later date is displayed
Quality system points are awarded beginning the month after the date of the Quality System; example, supplier achieve ISO/TS16949:2002 with Visteon Customer Specific Requirements on 21st February 2007, the supplier will receive 30 points from March 2007 onwards, after the March 2007 data run
The Visteon Customer
Specific Requirements for use with ISO / TS16949:2002 are available from
the Visteon Supplier Portal (VSP).
| 2.5 Significant
Quality Event(SQE) - 10 points
| (back to
Table of Contents)
If a
supplier has 0 SQE's, they get the full 10 points.
| Standard
SQE |
minus 10
points, 3 month duration |
| |
| Major
SQE |
minus 50
points, 6 month duration
|
The Quality Rating points
deduction will start in the next month after the SQE entry. Example, a
Standard SQE is entered on 20th April, the 10 points deduction to the
Quality Rating will occur in the months of May, June and July.
If
a supplier has one or more SQEs they lose points for the most severe SQE.
SQE Examples
Major SQE
- Violation of Trust
which includes but is not limited to the following:
- Changing
manufacturing site location without notification via the SCR process.
- Changing
sub-suppliers without notification via the SCR process.
- False or
unverifiable information being input into Scorecard / Report Card.
- False or
unverifiable information being submitted with a PPAP submission
Standard SQE
- Caused a stop
shipment or production stoppage at a Visteon
- Manufacturing
Facility.
- Caused a pass thru
rejection at a Visteon Customer.
- Caused a recall or
campaign.
- Unacceptable PPAP
submission(s) is received following appropriate instruction.

| 2.9 Quality
Rating Weighted Average
| (back to
Table of Contents)
A 6
month weighted average is used to compute an overall Quality Rating
figure. This figure is used by Visteon for business decisions. The rules
for calculating the Weighted Average Quality Rating are as follows:
The last calculated Monthly Quality rating is excluded from the
weighted average as this month's data is deemed to be immature. The
weighted average is over six months with weights of 6, 5, 4, 3, 2 and 1 in
reverse order from latest mature data month. The summed total is divided
by 21 to achieve the Six Months Weighted Rolling Average Quality Rating.
Details of the calculation are accessible form the summary screen.
If a supplier is
new or has been supplying for less than 6 months or the number of ratings
received is below 6 months then the six month rolling weighted quality
rating will be calculated ONLY for the months that the rating is
available. The weight for the months available is assigned in reverse
order from the current month.
(e.g. If for August, the ratings are
available for Jul, Jun, Apr, Mar, Feb, Jan then the weight for the months
will be 6, 5, 0, 3, 2, 1. Note here that the month May is missing and is
therefore assigned a "0").

The Negotiating
Entity functionality is not activated. Future plans to introduce
Negotiating Entity functionality will be communicated via Bulletin Board
notices.
