htttp://asqbuffalo.com About the program: While the Cause & Effect Diagram has a narrow focus in the analysis of a failure, The Good, The Bad and The Unknown Matrix goes far beyond to give you a full understanding of the process. The Good, The Bad and The Unknown Matrix is a new analysis tool that goes further than the Cause & Effect Diagram can go, being applied to different situations. This presentation will cover multiple application examples. About the Speaker: Al Germann is Senior Member of ASQ and holds CSSBB and CCT certifications. Al celebrates his 30th year working in industry and held various positions such as Quality Engineer for Metrics, Supplier Quality Engineer, Quality Manager, Project Manager and Metrologist. Employment history includes GE Transportation, Excelco/Newbrook (supplier of assemblies to the US Navy), Prestolite Electric, Woodward HSC (aerospace), and Lakeside Precision (industrial machine shop). htttp://asqbuffalo.com

6. General process steps:
 Identify the problem
 Brainstorm contributors into 6 categories
 Evaluate and prioritize items listed
 Select top few & develop an action plan
The C&E diagram is very focused on
what went wrong,
causing the problem.

If something goes wrong with the output, why focus
only on some of the inputs or some of the process
steps?
Find The Good,
Find The Bad,
Reduce the Unknowns.

11. • Can rule out some interactions.
Good • Captures good practices that can be used elsewhere.
• Captures information that leads to determining root
Bad cause (like C&E).
• Reduces the unknowns.

22.  The Cause & Effect Diagram is very good at
what is does, is well proven and has a long
history. However, it is very focused and may
not be the best choice.
 The GBU Matrix is great analysis technique
for your Quality Tool Box

23. The GBU Matrix helps to fully understand the
entire process by:
 Being an effective team based tool used for root
cause analysis.
 Displaying all that was discovered related to the
process, nonconformance or event.
 Helps to recognize the true state of the process,
event or business KPIs.
 Others: ?

24.  Immediately providing a clear illustration in
useable categories.
 Closed loop system with action items.
 Provides balanced and useful feedback to
work cells or teams.

25. The GBU Matrix:
 Use with or without prompting column
 Applicable to manufacturing, service &
transactional processes
 Use with 5S, Kaizen events or for After Action
Review, Process performance review
