Six Sigma is a quality improvement methodology developed by Motorola, focused on eliminating defects to achieve 99.9997% defect-free processes and products. It utilizes a data-driven approach with the DMAIC framework (Define, Measure, Analyze, Improve, Control) and emphasizes continuous improvement, organizational commitment, and measuring performance to enhance business processes. While the methodology offers advantages such as increased customer satisfaction and improved profitability, challenges include a lack of interest in statistical aspects among some engineers and communication barriers between statisticians and management.

1. Introduction to Six-Sigma
Welcome

2. What is Six Sigma?
Six Sigma is originally developed by Motorola to
systematically improve processes by eliminating defects.
 Sigma is the Greek symbol used for Standard Deviation
of population.
 Six Sigma is a statistical measure of quality, which
reflects process capability;
being 99.9997% defect free in process and product.
Mr. Bill Smith
at Motorola in 1986

3. The quality improvement methodologies such as Q.C, TQM, and Z.D. Like
its predecessors, Six Sigma asserts the following:
 Continuous efforts to reduce variation in process outputs is key to
business success
 Manufacturing and business processes can be measured, analyzed,
improved and controlled
 Succeeding at achieving quality improvement requires commitment
from the entire organization, particularly from top-level management

4. Difference between 3Sigma & 6Sigma
at 3 sigma. . .
•There are 964 U.S. flight
cancellations per day.
•The police make 7 false
arrests every 4 minutes.
at 6 sigma. . .
• 1 U.S. flight is cancelled every 3 weeks.
• There are fewer than 4 false
arrests per month.

6. Elements of Six Sigma
•The Customer
•The Process
•The Employee

7. Methodology of Six sigma
D M A I C
• Define
• Measure
• Analyze
• Improve
• Control

8. D - DEFINE
Define project boundaries (scope) the stop and start
of the process
Define who customers are, what their requirements
are for products and services, and what their
expectations are ?

9. • M - Measure
Measure the actual perfomance which was
previously planned.
Collect data & Develop a data collection
Compare to customer survey results to determine
shortfall

10. • A- Analyze
Analyze the data collected and interpret it,
determine the defects.
Find the solution to minimize the defects.

11. I- Improve
After minimizing defects improve your target
customer by thinking innovately.
•Create innovate solutions using technology and
discipline

12. C- Control
Institutionalize the improvements through the
modification of systems and structures (staffing,
training, incentives)
Control undefined problems or action plans

13. What Six Sigma involve?
Brainstorming sessions to identify important factors
Conducting a few experimental trials
Recognising significant factors which influence a process
Setting these factors to get maximum output.

14. When to use Six Sigma?
Unknown Situation
In a complex situations

15. Why to adopt Six sigma?
Process for problem solving
Consistency with results

16. Six sigma levels
3 levels/Belts
1-Green belt
2-Black belt
3-Master Black belt

17. How Six Sigma is practised?
-Focus on experimentation.
-Black Belt is coached by champion.
-Results are quantified.
-Stretched targets.
-Projects are of top priority.

18. Advantages of Six Sigma?
Better monitoring of processes
Better involvement of people
Staff morale is raised
Throughput is increased
Profits go up
Customer satisfaction.

19. Disadvantages of Six Sigma?
Engineers and managers are not interested in
mathematical statistics
Statisticians have problems communicating with
managers and engineers
