Scrap Metal COPQ Analysis LEAN SIX SIGMA BLACK BELT PROJECT FOR LAWRENCE TECHNOLOGICAL UNIVERSITY
In the analysis performed by an employee of scrap metrics and environmental
compliance measurements, customer supplied detail of scrap metal sales didn’t
agree with internal purchases. Further investigation by the employee indicated
inconsistent pricing of scrap metal. Combining these factors, the critical to quality
factor was developed utilizing a third party audit of the measurement process and
identifying the sigma level. Finally, improvement processes were implemented
with control features to optimize the process and scrap metal sales. This resulted
in surpassing yearly goals for scrap dollar sales but not achieving quality goal
standards due to the extrapolation from the sample was not representative of the
2013 population. The increase in cross contamination was due to the
implemented improved measurement procedures. Management
recommendations for lean process improvements will improve overall scrap metal
sales, sigma level for cross contamination of scrap metal, and operational
production efficiency though problem solving issues utilizing scrap metal metric
indicators.

EXECUTIVE SUMMARY
By performing the Lean Black Belt study on scrap metal sales, the organization was able to realize an
increase in scrap metal sales even with an abnormally high level of scrap metal cross contamination. In
the fiscal year of 2013, the organization increased scrap metal sales by $182,021.84 or 47.2% from the
previous year. This exceeded the yearly goal of $87,972.16 or 22.8%, derived from a sample 3 rd party
audit of a single scrap metal delivery. The yearly results could have been higher due to the devaluation
of overall metal prices in 2013 from 2012.
The Cost of Poor Quality (COPQ) represented in the cross contamination of the scrap metal proved
harder to improve. From the 3rd party audit of the scrap metal process, the estimated range of the cost
of cross contaminated metals was from $13,494 to $31,919. The actual level of cross contaminated
metal in 2013 was $23,941. Even though the value of the COPQ was within the range of the estimate,
improved measurement of defects in 2013 indicated a higher defect level of 1.5 Sigma. Thus, the scrap
metal sample audit was not a true representative of the entire population signifying an opportunity for
future improvement.

DATA COMPILATION
Yearly accounting of the scrap metal volume by metal type is required by the EPA for environmental
compliance (TRI Report). The reporting by the scrap metal purchaser provides to the government and
selling organization the type and quantity of scrap metal provided for sale. Upon review by the Moeller
Manufacturing Environmental Health and Safety Officer (Sean Paul, EH&S), the scrap metal purchaser
during 2010-12 provided total and segmented scrap metal volumes that didn’t match internal detail or
responses by the scrap metal purchaser. The EH&S officer launched a detailed analysis to verify the
data to the EPA (See Appendix regarding Early Scrap Metal Problem Identification, Calculation,
and Cross Contamination Letter). The detailed spreadsheet indicated the overall scrap metal cross
contamination at a level exceeding 50%, pricing the metal at low value steel. The spreadsheet was
verified by the Master Black Belt (Gary Kapanowski). The next step was to visually inspect the
production floor to see if this cross contamination level is actually occurring.
GEMBA WALKS
Project team visually reviewed production floor operations and procedures to verify the external
vendors reporting of the scrap metal sales. Upon three different review opportunities, the team didn’t
experience excessive levels of cross contamination. The findings resulted in zero cross contamination
defects and validated the current processes. Defects were noted in the internal manual shipping log.
The process audit on the manual shipping log indicated an employee issue for the defects. A change in
both the manual shipping log and employee was instituted in 2013 for process improvement and
improved measurement data.
THIRD PARTY AUDIT TEST
The goal for the third party audit test was to verify the discrepancy of the scrap mix and total weight
represented by internal and external metrics as seen in the EPA environmental compliance reports (TRI
Reports). The project team met with a new vendor (East Side Metals / RJ Torching) to perform the audit
of one scrap metal shipment on 12/20/12 before the original vendor receives the shipment. The new
vendor will report and validate the scrap metal volume mix, internal processes, and the value of the
4
scrap metal. The scrap metal shipment was returned sealed and released to the original vendor for
accurate comparison. See the Appendix section for Audit procedures and detailed results.
The audit indicated the shipment value exceeded the original vendor’s value by $1,496.66 or 22.8%. The
Project team requested additional testing to validate the 22.8% metric. Management decided the
metric was acceptable for this project to continue and use as the goal for 2013.
PROJECT CHARTER
The project team successfully completed a project charter authorized by management as the sponsor.
The following are the key details agreed to execute the project charter into operations:
Project Description: To maximize the value for scrap metal throughout the organization.
Business Case: By not following basic operational procedures, the scrap metal barrels
experience cross contamination which cost an average $13,494 to $31,919 per year.
Problem Statement: Per third party audit of the scrap metal process on 12/18/12 and historical
data as background information, the Cost of Poor Quality (COPQ) for scrap metal is in the range
of $13,494 to $31,919 in cross contamination per year due to poor internal processes and
adherence to current procedures. Overall scrap metal sales increase by audit representative
percentage of 22.8% or $87,972.16.
GOALS:
o 0 barrels of cross contamination per week
o 2% overall AVG of cross contamination per barrel
o 3% overall AVG of liquid weight
o 2013 scrap metal sales $473,814.96
Expected Business Results:
o Increase in scrap value through reduction in cross contamination: $13,494 to $31,919
per year
o Increase in scrap value though improved scrap metal pricing: $87,972.16
o Lower average % of cross contamination per barrel: Lower than 3%
o Lower per barrel defect in cross contamination: Zero per year
o Lower machine maintenance cost per year
5
o Improved production efficiency per year
o Reduction in scrap units per year
o Improved production problem solving using the symptom of scrap metal from barrels to
indicate inefficiencies at specific machines
Expected Customer Benefits:
o Improved delivery time through improved production efficiency and quality due to
reduction in scrap units and improved problem solving tools
CRITICAL TO SUCCESS FACTOR
The project team determined quality was the critical to success factor for this project. Due to the EPA
environmental compliance issue, proper reporting of scrap metal is vital to comply with the
organization’s mission statement authorized by management and reviewed by the AS9100 and
ISO14001 internal and external auditors.
LEAN SIX SIGMA STUDY
The team followed the six sigma steps for DMAIC as described by the LEAN SIX SIGMA POCKET
TOOLBOOK (George, Rowlands, Price, & Maxey). This section will review the detail behind each step to
implement process improvement to reach the metric goals. The team performed a Lean Six Sigma A3
presentation to clearly identify the DMAIC process.
DEFINE
The project charter was approved with measureable goals as described in the PROJECT CHARTER section
above. This included validating the problem statement, goals, and financial benefits. A process map
and SIPOC diagram was completed to assist with the identification of critical to success factors.

MEASURE
The current and future state process maps were completed by the team to identify the critical issues
needed for success. The team agreed the measurement system was poor due to the manual nature of
the process and lack of detail as viewed during the GEMBA WALKS. The team obtained approval from
the sponsor to perform a third party audit of a sample scrap metal volume and mix along with a review
of the process. The audit validated the need for a new measurement system and developed a baseline
used in the project charter for the project goals. The details on the audit are listed below:
52 barrels containing a total of 6,699 lbs. with 4,971 lbs. for scrap metal
Average estimate 3% of cross contamination per barrel
The individual barrel weight ranged from 17 lbs. - 280 lbs., avg. of 96 lbs.
One barrel was 45% cross contaminated
63% of sample is under the 3% avg. for cross contamination per barrel
AUDIT STATE: 2.5 Sigma DPMO 19,231 Yield 98.08%
CURRENT STATE: 2.0 Sigma DPMO 45,400 Yield 95.46%
FUTURE STATE: 3.0 Sigma DPMO 2,700 Yield 99.73%
Due to the limited availability of accurate measurable data or additional audit samples, the capability of
the scrap metal sales process couldn’t be identified at this time. After a full year of data with the
improved data measurement process installed, this capability of the process will be identified to
advance the process improvement of the scrap metal sales. A cause-and-effect diagram (Ishikawa
diagram) was completed at this time to verify if other inputs were necessary to validate other than the
measurement system (See Appendix). The identification of cross contamination, collecting of the scrap
metal data, and pricing of scrap metal were considered as a priority in testing for Analyze.
Several Lean initiatives were identified and implemented during this process since there was no risk to
the project or other processes. The team changed the internal reporting from manual to an electronic
format to error proof (poka yoke) the data entry process. The team also implemented an employee
change to expedite change.

ANALYZE
The team reviewed the audit results and determined the scrap metal vendor was the main cause for the
Cost of Poor Quality (COPQ). This was identified through the process of completing the problem solving
report utilizing the cause-and-effect diagram (See Appendix). The 5Whys was used to determine the
root cause of the problem was the cross contamination of scrap metal, either internal and/or external.
The third party audit identified the cross contamination defects were originating from the scrap metal
vendor. This analysis allowed for the team to pass on additional statistical analysis and implement a
change scrap metal vendor to start in January 2013.
Although the third party audit sample indicated a 2.5 Sigma (1 barrel per week or 52 barrels per year),
the real current state is 2 Sigma (2 barrels of contamination per week or 123 barrels per year) based on
overall risk assessment and a single audit sample for analysis. By implementing changes in procedures,
the scrap metal Cost of Poor Quality (COPQ) will fall to 3, 7 barrels per year.
Several of the audit results were reviewed in detail, see below:
There were eight barrels with average of cross contamination exceeding 3% representing 18% of
the sample size weight
o ALUMINUM P13D4 5% (defect)
o A286 P12D3 1%
o INCO 718 P3D4 1%
o INCO 718 P3D4 1%
o SAW MIX P13D2 3%
o TI P10D4 2%
o TI P13D3 2%
o UNKNOWN P12D1 2%
o UNKNOWN P7D2 2%
To complete the root cause and significant cause-and-effect relationship for the potential causes, the
team used brainstorming, Cause & Effect matrix, and Pareto charts validate the search drivers (See
Appendix).
8
A failure mode and effect analysis (FEMA) was completed to identify and mitigate risks. Each input was
validated with at least one selection in the FEMA. Of significant note, the risk of achieving future gains
in scrap metal sales still reside in implementing the lean initiatives as described in the FUTURE
IMPLEMENTATION IDEAS section. Each initiative will improve the process of collecting Scrap Metal,
Identifying Cross Contamination, and improve the recording of Scrap Metal.
The project team completed the Project Risk Assessment to determine the overall project risk at a low
level. This indicates to the project team that there are several factors that are not in their control that
could affect the successful outcome of the project. Monitoring and providing proactive adjustments to
the project will mitigate the risks. The project team also successfully completed a Project Check Sheet
and Project Check List indicating all necessary aspects to complete a Lean Six Sigma project was
addressed (See Appendix).
IMPROVE
As seen in the ANALYZE phase, the implementation of the new scrap metal vendor was launched in
January 2013. This was clear to the project team since the old scrap vendor was involved in every failure
mode identified in the analysis. Addressing the three inputs selected in the analysis section will assist in
achieving the project goals. By adding new procedures for collecting scrap metal, the organization can
reduce the overall defect rate for cross contamination and increase the scrap sales at the optimum level.
Some procedures were implemented to address this issue but the main issue of replacing barrels when
the metal of the operation is still in process. Identification of cross contamination is the second
improvement identified in the analysis section. Since this is sometimes difficult to identify different
metals, new procedures and equipment are necessary to validate scrap metal types which will identify
potential cross contamination. The third input for improvement is the pricing of the scrap metal. After
the new vendor is implemented, the procedure for the review of the scrap metal prices was
implemented to validate the prices used per the sales calculation. This will eliminate any defect in
pricing and allow for a more transparent business relationship.
Other potential solutions were evaluated and selected to optimize the operations. The “Future State”
process map was utilized as the optimization of the process. Each solution was tested as attainable and
didn’t incorporate “scope creep” since they reflected the project goals and organization’s goals. The list
of the additional solutions is presented below:
9
Lean Continuous Improvement Initiatives
o Barrels need to be cleaned before use in scrap area
o Each machine needs to be cleaned before change of metal or usage
o Increase number of barrels for scrap metal
o Number barrels with machine
o Weight of barrel indication
o Adequate baseline for metrics
o Enhance reporting documents for scrap metal
o Fluid weight issue to fully understand the scope for our activity
Optimize operations by utilizing new metrics
o Obtain baseline metrics for cross contamination and fluid weight
o Identifying the symptom downstream will indicate the problem upstream
o Analyze fluid weight for improvement in effectiveness and efficiency
o Prepare team members for change, measure results to see where future issues can be
resolved
Obtain industry baseline standards for fluid weight issue to properly measure our results and
maximize value throughout the system
CONTROL
Starting on 1/1/2013, updated procedures were installed to monitor and control the scrap metal sales
process. The operational procedures were transferred from maintenance into quality with the project
team member Sean Paul, EH&S Officer and the responsibility center. The accounting and management
communication of the process was transferred from Accounting into the project team leader, Gary
Kapanowski, Master Black Belt. Updated electronic processes and reports provide error-proofing of the
data. Monthly reporting of the project and metrics communicated to management and the sponsor.
Two-way communication with the new scrap metal sales vendor provided full transparency of the scrap
detail and a formal process to resolve problems (See Appendix for monthly control charts for COPQ and
Final A3 charts). After the fiscal year is complete and metrics obtained, the operational control will
return to Accounting.
The control measures and metrics used for this project are as follows:
10
Increase in scrap value: $13,494 to $31,919 per year
Cost in scrap metal per barrel is on average $259.50
Lower average % of cross contamination below 3% per barrel
Lower per barrel defect in cross contamination: Zero per year
Lower machine maintenance cost per year
Improved production efficiency per year
Reduction in scrap units per year
Improved production problem solving using the symptom of scrap metal from barrels to indicate
inefficiencies at specific machines
LEAN SIX SIGMA FINAL RESULTS
The results were mixed during the first year of implementation ending in the fiscal year 2013. The listing
below will indicate the year end metrics:
Lower per barrel defect didn’t achieve the goal of 0 barrels
o Cost of cross contaminated equated to $23,941
o Cost per cross contaminated barrel equated to $81.71, favorable to goal of $259.50
Lower overall 3% of average of cross contamination per barrel across production operations
didn’t achieve the goal
o Number of barrels with cross contaminated at 293 or 9.2%
o The DPMO equates to 90,818, yield of 90.8% or a 1.5 Sigma level
Obtain industry standards on fluid weight with a goal of 3%
o Improvement to reduce fluid in scrap metal delayed by sponsor due to capital
investment outside of the scope of the project
Overall yearly scrap sales yearly goal increase of $87,972.16 or 22.8% attained
o Year-to-year increase in 2013 at 182,021.84 or 47.2%
Lower machine maintenance cost year-to-year achieved with a 36.3% reduction
Improved production efficiency year-to-year achieved with a 28.7% gross margin improvement
Reduction of scrap units year-to-year achieved : 2.67% reduction
Improved production problem solving using symptom of scrap metal implemented in Top 30
part cost reduction team
11
Customer scorecard regarding delivery time and quality indicates above standard or baseline
achievement in 2013
RISKS OR CONSTRAINTS
The scrap metal price volatility and volume mix provides an overall risk to the levels of scrap sales. Also,
the organization is not formed to generate scrap sales but making good parts - to customers - on time.
Thus, since the scrap metal mix profile is always changing and focusing on the organization’s goal, any
micro-managing to optimize the scrap metal sales beyond the company’s vision and mission will lead to
inaccurate direction and results for the organization.
LESSON LEARNED
Implementation of Lean Six Sigma initiatives can be instituted and exceed stated goals within one fiscal
year.
FUTURE IMPLEMENTATION IDEAS
One Lean Six Sigma initiative not implemented due to the sponsor determination the issue was outside
of the project scope was to obtain industry baseline standards for fluid weight to properly measure our
results and maximize scrap metal value throughout the system. The equipment investment cost is
$20,995 with a return on investment of 24 months. The project team re-affirms the incorporation of this
initiative purely on a cost benefit ratio (See Appendix on Return on Investment).
Improvement of the cross contamination of scrap metal can be fixed by using more barrels. By
swapping barrels for each production operation of different metals will eliminate the issue by definition.
The organization can obtain additional scrap metal barrels without cost though the vendor. The project
team re-affirms the incorporation of this initiative purely on a cost benefit ratio.
Using the scrap metric by specific equipment will indicate if the operation is in control with measurable
data. This is the next step in problem solving in operational management for the organization.

Environmental Health and Safety Officer Sean Paul’s Early Scrap Metal Problem Identification:
The scrap metal project was started from analysis required of metal sent off site for recycling. This is an EPA requirement. While summing the receipts from our scrap metal recycler, I noticed that the recycler was claiming that we were sending him huge amounts of steel and not the alloys we machine. An example would be we would send 8 barrels of a valuable super nickel alloy, the receipt would only show 2 barrels of super nickel alloy and 6 barrels of steel. The recycler kept claiming a 40% or more cross contamination rate was “forcing” them to devalue huge portions of our recycled metals.
I spent the next year adding up every receipt from the metal recycler and compared with the current market values listed from recognized sources like the London Metal Exchange (LME) and the current market pricing for options and futures. By the end of the first month of analysis I was absolutely convinced the recycler was not acting in an honest manner.
Environmental Health and Safety Officer Sean Paul’s Early Scrap Metal Problem Calculation:
Per the analysis of the historical data and assumption of the level of cross contamination equates to 1 in 5 drums or 20%, per claim by the original scrap metal vendor, Regal Recycling, the estimated increase in scrap metal value for 2013 is $165,213. Other assumptions used to estimate the cost of the misclassification of metals include stable production levels year to year.
The actual difference in scrap metal sales proved to be close to the estimate. With the actual sales difference of $182,021.00, the difference from estimate is only 10.17%. The actual contamination rate was less than 10%, while my original estimate was very conservative at a 20% contamination rate. If we take the values of my estimate and utilize the actual rate of 10%, the overall difference is minor.
A good example would be Inconel (Inco) 718 which is one of the highest volume metals we processed in both 2012 and 2013.
2012: Scale tickets from Regal stated we shipped 54,306 pounds of Inco 718. I estimated that even if we contaminated 20% of the barrels that we should have sent another 37,920 pounds of Inco 718 for recycling. This would have been a total of 92,226 total pounds of Inco 718 for calendar year 2012.
2013: The scale tickets from RJ Torching show we shipped 96,333 pounds of Inco 718, a 4.3% variation from the estimates that were established in the analysis 2012. This is a true representative of the amount since 2013 production reduced by 1.6% from prior year.

THIRD PART AUDIT PROCESS AND RESULTS: 12/20/12
AUDIT STEPS UTILIZED IN THE 3RD PARTY AUDIT
1. Normal pickup on the 20th for Regal Recycling, original vendor
2. Bring RJ Torching representatives on site 12/18 and 12/19
3. Run the third party truck on 12/19 to the nearest state police scale; contact freight to find nearest state police scale and time that they are available.
4. One sample for RJ Torching to work on the sample without interruption.
5. Talk with internal supervisors to prevent any tool steel drums from the sample. This eliminates any inclusion of steel in the sample size.
6. Identify number and operators of the fork truck drivers in case of errors or communication to Regal Recycling, original vendor.
7. Log and mark each drum for metal and cross contamination.
8. Lock the trailer when the audit is complete to prevent addition or deletion of any drums from the sample.
8. Report any observation by RJ Torching’s to better improve the process and controlling scrap metal.

DETAIL PER SCRAP AUDIT: 12/18/12
1. A third party documented a sample size of 52 barrels containing a total of 6,699 lbs. of which 4,971 lbs. was for scrap metal; the difference is in barrel weight.
2. The average estimate % of cross contamination per barrel within the sample size was 3%a. This average level of cross contamination is not a concern for the value chain per third
party auditors3. The individual barrel weight ranged from 17 lbs. to 280 lbs. with an average of 96 lbs.
a. Per past experiences and review of the audit sample of barrel label of metal and the audited four staged verification of the contents, contamination occurrences are most likely for heavier barrel weights due to barrel use in multiple operations increases with weight.
b. For our calculations, we will limit the exposure to the TOP 15 barrel weights from this sample as the extrapolation for the COPQ calculation (173 lbs.).
4. One barrel was 45% cross contaminated and considered as null value and a quality defecta. This represents 1.92% of the sample population (1/52) or about a 2.5 Sigma level
5. A review of the metal segment groups indicate that 63% of the metal segment group weight is under the 3% average for cross contamination
6. The metal segment groups with an average of cross contamination exceeding 3% are the following, represented as a % of the sample size weight:
Aluminum: 9% A286: 1% TI: 14% UNKNOWN: 13% TOTAL: 37% of the sample size weight
7. There were eight barrels with average of cross contamination exceeding 3%a. This representing 15.4% of the sample size in quantity (8/52) and 18% of the sample size
weight8. Based on individual barrels with an average of cross contamination exceeding 3% are the
following, represented as a % of the sample size weight: ALUMINUM P13D4 5% - indicated as a quality defect per
third party auditors A286 P12D3 1%
17
INCO 718 P3D4 1% SAW MIX P13D2 3% TI P10D4 2% TI P13D3 2% UNKNOWN P12D1 2% UNKNOWN P7D2 2% TOTAL: 18% of the sample size weight
9. Cost of Poor Quality (COPQ) for cross contamination of barrels for the sample size was calculated
a. The barrel with 45% cross contaminated was of Aluminum, Drum# P13D4, priced at $0.50 per lbs.
b. Resell the cross contaminated barrel at $0.06 per lbs.c. The difference of $0.44 is used for pricing calculationsd. The weight of the metal was 257 lbs. for the cross contaminated barrel, Drum# P13D4e. This calculates into $113.08 per cross contaminated barrel using the audit as the
baseline, Aluminum pricingf. Risk Analysis:
i. There is a risk to the analysis if the scrap metal is not always Aluminumii. There is a risk to the analysis if the scrap metal weight per barrel is not always
257 lbs. (top end of the audit sample size)iii. Aluminum represents only 9% of the sample size: thus, there is 91% available in
other scrap metaliv. Price for Aluminum is $0.50 per lbs.v. Average price for all 2012 scrap metals used in the shop is $1.56 per lbs.
vi. The price for INCO, most used scrap metal at 15% of sample size, ranges from $1.90 to $6.40 per lbs.
g. Metrics for COPQ utilizing the Audit Sample data with risk analysis inputi. Overall metrics for Cost of Poor Quality (COPQ) for scrap metal value per barrel
is the following:1. Price Aluminum: $76.122. Price 2012 Scrap Metal AVG of $1.56: $259.503. Price INCO - Low is $1.90: $318.324. Price INCO - AVG is $3.46: $588.205. Price INCO - High is $6.40: $1,096.82
ii. Overall Sigma Level and State financial impact for Cost of Poor Quality (COPQ) for scrap metal value:
1. 2 Sigma - Probable Statea. Price Aluminum: $9,362.76b. Price 2012 Scrap Metal AVG of $1.56: $31,918.50c. Price INCO - Low is $1.90: $39,153.36d. Price INCO - AVG is $3.46: $72,348.60e. Price INCO - High is $6.40: $134,908.86
18
2. Moeller 2.5 Sigma - Current Statea. Price Aluminum: $3,958.24b. Price 2012 Scrap Metal AVG of $1.56: $13,494.00c. Price INCO - Low is $1.90: $16,552.64d. Price INCO - AVG is $3.46: $30,586.40e. Price INCO - High is $6.40: $57,034.64
3. 3 Sigma - Future Statea. Price Aluminum: $532.84b. Price 2012 Scrap Metal AVG of $1.56: $1,816.50c. Price INCO - Low is $1.90: $2,228.24d. Price INCO - AVG is $3.46: $4,117.40e. Price INCO - High is $6.40: $7,677.74
4. 6 Sigma - Ideal Statea. All scenarios are at $0.00 cost
h. Conclusioni. Due to the overall sigma level, scrap mix, and scrap production processes, the
risk assessment indicates the following:1. Current State is realistically at 2 barrels of heavy contamination per
week or 2 Sigma Level; there is a chance the one barrel per week which will be accounted for in the range
2. Overall weekly quantity of 52 barrels is on the low end of the average per known data for 2012. Thus, the adjustment from the one time audit sample of one contaminated barrel to two is not out of the statistical average for the sample size
3. The price of the 2012 scrap metal average is the most appropriate value for the study since the overall scrap distribution isn’t heavily concentrated in a few metals
4. By implementing changes in procedures, the scrap metal Cost of Poor Quality (COPQ) will fall to 3 Sigma Level
ii. Current State impact of scrap metal Cost of Poor Quality (COPQ)1. Upper Control Limit: $31,918.502. Lower Control Limit: $13,494.00
iii. Future State impact of scrap metal Cost of Poor Quality (COPQ)1. Upper Control Limit: $1,816.502. Lower Control Limit: $0.00
iv. Metric per barrel for scrap metal Cost of Poor Quality (COPQ) 1. $259.50

Project Details
Project Description
To maximize the value for scrap metal throughout the organization.
Business Case By not following basic operational procedures, the scrap metal barrels experience cross contamination which cost an average $13,494 to $31,919 per year.
Problem Statement
Per 3rd party audit of the scrap metal process on 12/18/12 and historical data as background information, the Cost of Poor Quality (COPQ) for scrap metal is in the range of $13,494 to $31,919 in cross contamination per year due to poor internal processes and adherence to current procedures. Overall scrap metal sales increase by audit representative percentage of 22.8% or $87,972.16
