Six Sigma (6σ), Six Sigma as a Philosophy & a Metric, Six sigma methodology, Phases of Six Sigma

Six Sigma (6σ)

Sigma (σ) is a Greek term used in statistics to represent standard deviation from mean value, measures how far a given process deviates from perfection

• Higher sigma capability, better performance

Six Sigma (6σ) is a highly disciplined process that enables organizations deliver nearly perfect products & services

• A Vision & Philosophical commitment to consumers to offer the highest quality & lowest cost products
• A Metric that demonstrates quality levels at 99.9997% performance
• A Benchmark of product & process capability for comparison to ‘best in classes’
• A practical application of statistical Tools & Methods to help us measure, analyze, improve, & control our process

Misconceptions

• A standard
• A certification
• Another metric like percentage

Six Sigma as a Philosophy

Better Processes Reduce Cost

Six Sigma as a Metric

Six sigma methodology

• Business Process Management System (BPMS)
• DMAIC (Six Sigma Improvement Methodology)
• DMADV (Creating new process which will perform at Six Sigma)

Business Process Management System (BPMS)

• BPM strategies emphasize on process improvement & automation to derive performance
• Combining BPM strategies with sigma six is most powerful way to improve performance 
• Both strategies are not mutually exclusive but some companies produced dramatic results by combining them

DMAIC (Define, Measure, Analyze, Improve & Control)

• A logical & structured approach to problem solving & process improvement
• A quality tool which focus on change management style

Phases of Six Sigma are:

• Define specific goals to achieve outcomes, consistent with customers demand & business strategy
• Measure reduction of defects
• Analyze problems, cause & effects must be considered
• Improve process on bases of measurements & analysis
• Control process to minimize defects

DMADV

• Define the project
• Measure the opportunity
• Analyze the process options
• Design the process
• Verify the performance

Reasons for Six Sigma

• Customer Expectations
• Technological Change
• Global Competition
• Market Fragmentation

Benefits of Six Sigma

• Generates sustained success
• Sets performance goal for everyone
• Enhances value for customers
• Accelerates rate of improvement
• Promotes learning across boundaries
• Executes strategic change
