Six Sigma is the application of Statistics to a Process or a Product. The Below table gives the relationship between Six Sigma and Scrum Roles
|
Six Sigma |
Scrum |
|
Champion |
Product Owner |
|
Black Belt |
Scrum Master |
|
Green Belt |
Team Member |
Choosing the right project to apply Six Sigma where Important Customers and Stakeholders are involved which is critical for the Growth of the Organization in terms of Revenue and other Process Assets.
Six Sigma Frameworks
DMAIC-Define, Measure, Analyze, Improve, Control used to Improve Existing Process and Products.
Design for Six Sigma-DMADV
DMADV-Define, Measure, Analyze, Design and Verify
Overview of DMAIC
|
D |
Define the Goals of Improvement activity. The Most Important goals are obtained from Customers |
Candidate for Six Sigma Tools will Be Project Charter, Process Map, Bench Marking |
|
M |
Measure the existing system. Establish Valid and Reliable Metrics to help Monitor Progress towards goals defined at previous step. |
KPI’s, Descriptive Statistics, Pareto Analysis. |
|
A |
Analyze the system to Identify ways to eliminate the gap between the current performance of the system or process. |
Cause and Effect Diagram, Brainstorming, FMEA |
|
I |
Improve the system. Be creative in finding new ways to do things better cheaper or faster .Use Project Management and Other Planning and Management tools to Implement the new Approach. |
Project Management Tools |
|
C |
Control the new system , you can use standardization such as ISO 9000 to assure that documentation is correct. |
ISO 9000 system, Reporting System |
Overview of DMADV
|
Define(D) |
Define the goals of Design Strategy |
|
Measure(M) |
Measure the factors Critical to stakeholders |
|
Analyze(A) |
Analyze the options in Meeting the goals |
|
Define(D) |
Design the new product , service or Process |
|
Verify(V) |
Verify the design effectiveness in the real world |
In Below Table we have given Key Performance Index(KPI) of Parameters which we can measure using a Formula , this formula is important in Implementing Metrics in your Organization.
It Should be measured at overall project level
|
Input/Measure |
Formula |
Example |
|
Total no of Risks identified Total no of unanticipated risks occurred |
(Total no of risks identified/(Total no of risks identified + total no of unanticipated risk occurred))* 100 |
Total no of risks identified = 6 Total no unanticipated risk=2 Risk identification efficiency % =(6/8)*100=75% |
It should be measured at overall project level.
|
Input/Measure |
Formula |
Example |
|
Total no of risks identified for risk mitigation No of risks Mitigated but occurred |
((No of Risks Identified for Mitigation- No Risks Mitigated but occurred)/ No of risks identified for Mitigation))*100 |
Total no of risks identified for mitigation =6 No risks mitigated but occurred=1 Risk Mitigation Efficiency %=(9/10)*100=90% |
|
Input/Measure |
Formula |
Example |
|
Total number of defects found by test team Total number of defects rejected by the customer Total number of defects found by customer during UAT |
((Total no of application defects found by test team- total no defects rejected by the customer)/Total no of defects found by test team + total no of defects found by customer during UAT))*100 |
Total no of defects found by test team =100 Total no of defects rejected by customer =10 Total no of defects found by customer during UAT=2 Test effectiveness %=((100-10)/(100 +2))*100=88.23% |
|
Input/Measure |
Formula |
Example |
|
Total no of fixed defects Total no of reopened bugs Total no of new bugs due to fix |
(Total no of defects reported as fixed-total no of reopened bugs)/(Total no of defects reported as fixed + total no of new bugs due to fix)*100 |
Total no of defects = 100 Total no of reopened bugs = 10 Total no new bugs due to fix = 5 Quality of fix %=((100-10)/(100+5))*100=85.7% |
Finally to Conclude we are able to understand the basics of Six Sigma an the Formula used in KPI’s to Implement Metrics and cover the measure part of Six Sigma , in case of comments and queries the Author Suresh Menon can be Contacted at Suresh@digitalstream.in
