What is Cost Of Poor Quality?
       COPQ is categorized into:
            Internal failure costs
            External failure costs
            Appraisal costs
            Prevention costs
       COPQ means not doing what is RIGHT the first time
       COPQ includes reworks, scraps, meetings with no purpose,
       etc.
       Hidden issues are usually more important than visible issues
       It is very important for organizations to direct their efforts to
       these hidden issues.
       While 6 sigma techniques can flatten the overall costs,
       management needs to ask the right questions so that these
       issues are effectively addressed.

Examples of COPQ

Where It All Came From
   Motorola noted that many operations, such as           Process Capability
   complex assemblies, tended to shift 1.5 Sigma        (Cp) is a metric that
   over time. So,
                                                        describes how well a
        a process, with a normal distribution and
        normal variation of the mean, would need        process
        to have specification limits of plus or minus   meets requirements.
        6 sigma in order to produce less than 3.4       This works only with
        defects per million opportunities.              a CENTERED mean.
        This failure rate can be referred to as DPO
        or DPMO.


   A Six Sigma Quality Level is said to translate
                                                          Process Performance (Cpk)
to process capability index values for Cp and Cpk
requirements of 2.0 and 1.5, respectively.              Similar to Cp, but accounts for
   To achieve this basic goal, a Six Sigma program      Process shifts and drifts
might then be able to produce at least 99.99966%
“quality” at the “process step” (i.e., no more than
3.4 defects per million parts / opportunities or
process steps if the process mean were to shift by
as much as 1.5 sigma).

Using the standard deviation, we can determine the proportion of the product/process which will
be between the upper and lower specification limits, and thus considered acceptable.

                           Application Availability (24 X 7, except for six hour maintenance
                           window each Sunday Morning). 1 defect = 1 minute lost.
                           30 day month, with four Sundays: 41,760 minutes or opportunities for
                           failure/error.
                           Defects/Opportunities * 1 million
                           (30 minute outage/41,760) * 1,000,000 = 718.39. Sigma Quality Level
                           = 4.69 (99.93% availability)

                       An Olympic sport person who shoots 398/400 (99.5%) is at
                               4.08 Sigma. 399/400 (99.75%) is 4.31.



                       If an airplane has 1 million parts, it will have 230 defective ones at
                            5 Sigma. (99.977% are good).


                       If you win 60% of your bets at Las Vegas, and bring home a
                           lot of $, your Sigma is only 1.75!

Improved Profitability
           Customer Satisfaction + Efficient Systems = Improved Profitability




         Three ways to improve financial performance:
         Increase Sales
             Improve Customer satisfaction and market position
         Decrease the Cost of Goods Sold
             Reduce variation and defects
             Understand root cause of issues and eliminate the source of problems
             Improve process performance and reduce waste using lean principles
         Increase Price
             If possible by adding more value added services or product features

COPQ is categorized into: Internal failure costs External failure costs Appraisal costs Prevention costs COPQ means not doing what is RIGHT the first time COPQ includes reworks, scraps, meetings with no purpose, etc. Hidden issues are usually more important than visible issues It is very important for organizations to direct their efforts to these hidden issues. While 6 sigma techniques can flatten the overall costs, management needs to ask the right questions so that these issues are effectively addressed. © 2002 – 2008 by Cobam, Inc.

So, describes how well a a process, with a normal distribution and normal variation of the mean, would need process to have specification limits of plus or minus meets requirements. 6 sigma in order to produce less than 3.4 This works only with defects per million opportunities. a CENTERED mean. This failure rate can be referred to as DPO or DPMO. A Six Sigma Quality Level is said to translate Process Performance (Cpk) to process capability index values for Cp and Cpk requirements of 2.0 and 1.5, respectively. Similar to Cp, but accounts for To achieve this basic goal, a Six Sigma program Process shifts and drifts might then be able to produce at least 99.99966% “quality” at the “process step” (i.e., no more than 3.4 defects per million parts / opportunities or process steps if the process mean were to shift by as much as 1.5 sigma). © 2002 – 2008 by Cobam, Inc.

It will likely Process Mapping take several waves of Six Sigma to start reaching the full potential of any software. Ask Measurement Systems Measure Analysis & Process yourself the following: Capability What analysis do we need the software for? Analyze Statistical Tests, Modeling & Root Cause Analysis How well will it integrate with existing software? Improve Brainstorming, Design of Experiments, FMEA, & Do we already own the software?

  • 47. Voice Of The Customer (VOC) DMAIC Methodology Define VOC is often full of emotions. We need to restate customer statements into fact-based, performance requirements that Why don’t you guys learn how to meet a we need to focus on schedule? Your service quality is too poor Identify Customer Collect Customer Data When will you learn how to provide service and a Customer first attitude? Analyze Customer Data Why don’t you tell us when there is a problem? Determine customer I sent out e-mail after e-mail with no response! (CTQ’s): Why do you try and make your customers CTQ – Critical To Quality CTD – Critical To Delivery responsible for your quality problems? CTC – Critical To Cost Your Cycle Time is unacceptable Cost, Quality, Features, Availability © 2002 – 2008 by Cobam, Inc. All rights reserved Six Sigma Executive Overview - 47
