What is Sigma ?
A term used in statistics to represent standard deviation, an indicator of the degree of variation in a set of a process
Sigma
4
What is Six Sigma?
A statistical concept that measures a process in terms of defects – at the six sigma level, there 3.4 defects per million opportunities
A philosophy and a goal : as perfect as practically possible A methodology and a symbol of quality

Why Six Sigma?
• At GE, Six Sigma added more than $ 2 billion to the bottom line in 1999 alone • Motorola saved more than $ 15 billion in the first 10 years of its Six Sigma effort • AlliedSignal reports saving $ 1,5 billion through Six Sigma.
10
Why Six Sigma?
Six Sigma is about practices that help you eliminate defects and always deliver products and services that meet customer specifications
11
Cost of Poor Quality
What is cost of scrap?
What is cost of rework?
What is cost of excessive cycle times and delays?
12
Cost of Poor Quality
What is cost of business lost because customers are dissatisfied with your products or services? What is cost of opportunities lost because you didn’t have time or the resources to take advantage of them?

40
Tools for Six Sigma
• Creating flowcharts of the step in a process – operations, decision points, delays, movements, handoffs, rework, loops, and controls or inspections. • A process map is illustrated description of how a process work. Process Mapping
41
Tools for Six Sigma
• DOE is a structured, organized method for determining the relationship between factors (Xs) affecting a process and the output of that process (Y). Design of Experiments or DOE
42
Tools for Six Sigma
• A group of rows and columns, with one set of increments marked along the X (horizontal) axis and another set of increments marked along the Y (vertical) axis. • The purpose of using XY matrix is to study and understand the relationship between what you are putting into a process and what your customer is getting out of it. • The XY matrix allows the team to identify gaps, areas for improvement. XY Matrix
43
Tools for Six Sigma
• The goal of this tool is to ensure that your measurement system is statically confident – that it’s both accurate and precise each and every time it is used. • Undertaken during Measure phase, your MSA determines whether or not you can take a certain measurement and repeat or reproduce it among different people who take the same measurement.
Measurement System Analysis
44
Tools for Six Sigma
• Process capability tool is the measure of a process being able to meet specification requirements and fulfill customer CTQ needs on a long term basis.
Process Capability Tool
45
Tools for Six Sigma
• Investigating a theory about the suspected cause (s) of a particular effect in a process to determine if it is correct. • It’s a compass that points you directly to the vital few factors that are most affecting your process. Hypothesis Testing
46
Tools for Six Sigma
• The manner in which a part or process can fail to meet a specification, creating a defect or non-conformance, and the impact on the customer if that failure mode is not prevented or corrected. Failure Mode Effect Analysis
47
Tools for Six Sigma
• A detailed assessment and guide for maintaining all the positive changes you, your black belt, and the project team have made. • It ensures that all your analysis and efforts stay in effect and that you have information at your disposal to prevent backsliding or a return to less than optimal performance standard. Control Plan
