Slide 3: 

What is Sigma ? Sigma A term used in statistics to represent standard deviation, an indicator of the degree of variation in a set of a process

Slide 4: 

What is Six Sigma? 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

5 HISTORICAL OVERVIEW In the mid -1980s ,Motorola under the leadership of Robert . W Galvin was the initial developer of six sigma. Bill smith a senior engineer and scientist in Motorola communication division invented six sigma. Motorola extended the Six Sigma methods to its critical business processes. With the help of six sigma higher goals were set for achieving reliability and quality. Motorola saved more than $ 15 billion in the first 10 years of its Six Sigma effort

Slide 9: 

Sigma Level Six Sigma = 99.99966%

Methodology of six sigma : 

The main aim of six sigma is customer satisfaction. An appropriate metric is design to measure satisfaction of customer. This is a process with interlinked activities that lead to the organizational goals. Employee must be inform about the processes and the objectives of the organization to motivate them.

Tools and Roles for Six Sigma

Slide 21: 

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. Tools for Six Sigma Process Mapping

Slide 22: 

DOE is a structured, organized method for determining the relationship between factors (Xs) affecting a process and the output of that process (Y). Tools for Six Sigma Design of Experiments or DOE

Slide 23: 

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. Tools for Six Sigma XY Matrix

Slide 24: 

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. Tools for Six Sigma Measurement System Analysis

Slide 25: 

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. Tools for Six Sigma Process Capability Tool

Slide 26: 

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. Tools for Six Sigma Hypothesis Testing

Slide 27: 

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. Tools for Six Sigma Failure Mode Effect Analysis

Slide 28: 

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. Tools for Six Sigma Control Plan
