The History of Six Sigma • “Six Sigma” originated at Motorola in 1982 • Early adoptors • Allied Signal (Honeywell) • General Electric • Six Sigma management philosophy today • A well-developed, thorough approach to quality improvement • Uses statistics and management by fact • Is effective in manufacturing and services firms
Defining Six Sigma (6) “Six Sigma: A comprehensive and flexible system for achieving, sustaining and maximizing business success. Six sigma is uniquely driven by a close understanding of customer needs, disciplined use of facts, data, and statistical analysis and diligent attention to managing, improving, and reinventing business processes.” - Peter S. Pande6
Defining Six Sigma (6) • The Greek symbol (sigma) refers to the amount of variation in a process around the mean value for that process • Processes have acceptable upper and lower limits • Six Sigma is concerned with reducing the variations to get more output within those limits
Defining Six Sigma (6) • In the chart below, 64.6% of the measures are between the upper and lower limits • This is a 1 process • Reducing the variations in the process will bring a higher percentage within the acceptable limits
The 6 Difference What is the Six Sigma difference ? • one typo per page (3 sigma) vs. one typo per library (6 sigma) • playing golf at a 6 sigma level means missing one putt every 163 years
Brainstorming Exercise:Where are the variations? Identify six processes in your business that have variations in the output. (HINT: manufacturing, purchasing, inventory, forecasting, product design, customer service, accounting...)
The Six Sigma Roadmap • Five steps to implementing Six Sigma9 • Identify core processes and key customers • Define customer requirements • Measure current performance • Prioritize, analyze, implement improvements • Expand and integrate the Six Sigma system
Organizing Six Sigma • Key Roles10 • Leadership Team • Champions • Mentors (master black belts) • Experts (black belts) • Participants (green belts)
Key Six Sigma Roles • The Leadership Group • Be actively involved from outset • Develop a strategic plan • Establish Roles and Infrastructure • Establish supporting policies • Job descriptions • Reward/Compensation systems • Career paths
Key Six Sigma Roles • The Leadership Group (cont’d) • Select projects • Prioritize projects and allocate resources • Facilitate, guide, manage
Key Six Sigma Roles • The Champions17 • Find appropriate projects • Represent projects to the leadership • Provide coaching • Ensure allocation of resources • Resolve issues
Key Six Sigma Roles • Master Back Belts • Coach and support project leads • Work as a change agent • Train others in the use of six sigma tools
Key Six Sigma Roles • Black Belts • Highly trained experts • Manage project leaders • Lead project teams
Key Six Sigma Roles • Green Belts • Trained in the use of statistical tools • Lead project teams • Participate on project teams
A Real-World Example • General Electric’s 6 results: - reduced invoice defects and disputes with a key customer by 98% - saved $1 million annually in contract review process (GE Capital) - developed breakthrough technology that reduced medical scan times to 30 seconds from 3 minutes - improved a key call center performance measure from 76% 99% - reduced vibrations in Power System rotors by 300% - saved $320 million in less than two years, $750 million in three years
Exercise • If you have a 2 sigma process, what percentage of the output is within spec ? • Six Sigma originated at Honeywell –T/F • Six Sigma focuses on the customer –T/F • What does the Greek symbol sigma represent? • Six Sigma utilizes fact-based decision making – T/F • Continuous improvement requires feedback and adjustments to ensure achievement of business objectives – T/F ANSWERS: 1) 94.38%, 2) False, 3)True, 4)Standard deviation, 5) True, 6) True
Six Sigma Summary • Project-driven management philosophy • Relies on fact-based decision making (statistical tools) • Requires top-down support • Requires an infrastructure that can support quality project management • Has been shown to have markedly positive impacts on business performance
