- Global 6-Panel Reporting standard
- 6-Panel Problem Resolution is a high level
problem resolution document to capture the key
requirements and data to drive decisions through
the problem solving phases Define, Measure,
Analyze, Improve, Control, and Replicate. - Assist problem solving teams with a template to
guide the problem solving process using minimum
required DMAICR steps to ensure robustness of
the resolution. - Individual summary panels of each DMAICR phase
that is simplified and standardized, while
allowing for additional information or slides to
be inserted as backup information for any of the
problem resolution phases. In a high level
management report out, communicate with the six
summary panels. For a team or quarterback deep
dive, unhide information on additional slides. - Standardization of problem resolution procedures
combining best practices and 6-Sigma methodology
on a format that is flexible enough to be used by
all business units. - Simplified and consistent communication to
management in a concise way without having to
rewrite what you have done. - Encourages management to ask questions in line
with the 6-Sigma disciplined methodology.

- DEFINE PANEL (Minimum requirements)
- Identify the Project Classification (Safety,
Quality, Deliver, Cost) objectives. Typical
quality classifications will be based upon the
Single Agenda for Quality data (both low time in
service, 3 MIS, and high time in service, 3 YIS)
from GQRS and Warranty. Include total annual
warranty spending and JD Power data if available.
In addition, use internal data indicators to help
identify the concern including Best In Class
(BIC) and Best In Ford (BIF) data to address
customer concerns. - Trend Charts and Breakdown of Issue (Internal or
External trends, and graphical quantification and
pareto formulates a means of prioritizing and
help reflect the teams understanding of the major
components making up the concern.) Data trend
charts over time help define the severity of
customer concerns. Data trend charts over time
should include annotative updates. If needed, add
backup slides. - Yf(x) Cascade (High level Yf(x) cascade should
communicate the scope of the project). - CTQ (Critical to Quality) Statement - identifies
customer requirements / expectations. - Defect Definition of Key Process Output Variable
(KPOV or Y) in the form of an engineering metric. - Cost of Poor Quality (Cost of the Problem
includes all external and internal cost, TGW,
Total Warranty Spending and Unexpended Warranty,
labor overhead, etc.) - Problem Statement (include scope and goal)
- Additional Tools (add slide(s) to capture backup
Define material) - Process Mapping (As Is), SIPOC, Is-Is Not
Analysis - Unexpended Warranty Calculations

thevehicle bottoms out, exhaust noise banging
on side of vehicle. CTQ STATEMENT (Customer
Requirement) Customers expect no ground out
noises from the exhaust system. DEFECT DEFINITION
for Y (Engineering Metric) Muffler to body
clearance less than 17mm at fascia COST OF POOR
QUALITY (TGW, Unexpended Warranty,
etc.) 350,000 annually in internal repairs and
external warranty. In addition, 2.5 TGWs from
3MIS GQRS surveys. PROBLEM STATEMENT, SCOPE, AND
GOAL Owners of 2001 MY Taurus/Sable vehicles
indicate that exhaust pipes and muffler to body
side ground outs are a significant issue. These
ground outs conditions, particularly around the
rear fascia lower control arm, cause noises
such as rattles, knocks, bangs, clunks, dings,
and rubs. Reduce ground outs by 90.

yf(x) The current design muffler assembly aid
positions the pipe to the center of tunnel, which
is 4.2 mm from design position. This translates
13 mm muffler body movement toward the fascia
area.
CURRENT ASSEMBLY AID 4.2 mm offset from design
allows pipe position to vary when installed
yf(x) Muffler assembly aids used during
installation require detailed 4.2 mm offset
