Six Sigma Definition
Six Sigma is a management philosophy that emphasizes setting extremely high objectives, collecting data, and analyzing results to a fine degree as a way to reduce defects in products and services. The philosophy behind Six Sigma is to measure how many defects are in a process, then figure out how to systematically eliminate them and get as close to perfection as possible. To achieve Six Sigma, a process cannot produce more than 3.4 defects per million opportunities, where an opportunity is defined as a chance for nonconformance.
Six Sigma Processes
Six Sigma DMAIC is a process that Defines, Measures, Analyzes, Improves, and Controls existing processes that fall below Six Sigma performance. Six Sigma DMADV Defines, Measures, Analyzes, Designs, and Verifies new processes or products that are intended to achieve Six Sigma level quality.
All Six Sigma processes are executed by Six Sigma Green Belts or Six Sigma Black Belts, which are then overseen by a Six Sigma Master Black Belt. These terms were created at Motorola.
What Is Six Sigma?
• Sigma (or ) is an operational concept that represents how much variation there is in a process relative to customer specifications
Imagine Two Lawns
Can I Measure Each Blade?
• If I measure each blade of grass, can I calculate the average length of the grass in the lawn?
• We would call that the mean or average length of the grass in the sample (one lawn)
• The mean or average lengthof all the grass in all lawns is called by the Greek letterμ (mu)
Can I Measure Each Blade?
• After I measure each blade of grass, can I calculate the difference between this blade’s length and the average length of the grass in the lawn?
• Can I calculate the average of how far each blade missed the average?
• This is called the sample standard deviation or s• The standard deviation
of all the grass in all lawns is called by the Greek letterσ (sigma)
Plot of the Variance
• If I plot how many blades of grass are at each length, I am likely to get a histogram that looks something like this picture.
Customer Perception Threshold
• When can I tell there is a difference in the length of the blades of grass as I drive by and look at the lawn from my moving car?
• When can I tell a difference in the length of the blades of grass if I am Tiger Woods putting to win a major championship?
• Each customer has a perception threshold and you must know what it is.
Plot of the Variance
• If I add the customer’s perception thresholds to the graph, I can begin to see how well my grass mowing process meets my customer’s needs.
Customer notices too short
Customer notices too long
How Good Are We?
• If I measure the number of standard deviations or σ’s that will fit between the average and the closest customer’s perception threshold, I can determine the Sigma Level

Examples of Process σ Levels
• If we accepted 99.4% (4 σ), then we would have:o 54 hours of cold showers per yearo Lights out for one hour per weeko 20,000 lost pieces of mail per houro 200,000 wrong prescriptions per yearo Unsafe drinking water 15 minutes per day
• With 6 σ (99.9997%) we would have:o 2 minutes of cold showers per yearo Lights out for 2 seconds per weeko 1.1 lost pieces of mail per houro 11 wrong prescriptions per yearo Unsafe drinking water 3 minutes per year

A Balanced Organization
• Jim Dickenson, James Chansler and Paul McElroy, with the input of others, developed four main areas that need to be balanced for a successful JEAo Financial Performanceo Customer Expectationso Organizational Effectivenesso Community Responsibility
Financial Performance
• Do we manage money responsibly, meet budgets and have the right level of debt?o Focus Areas
Liquidity: Maintain cash and cash equivalent levels that allow us to take advantage of market opportunities, withstand negative catastrophic events, and create strong credit ratings
Debt Management: Manage JEA’s debt with an overall philosophy of achieving the lowest possible interest cost, minimizing the amount of debt outstanding and protecting the bondholder with strong levels of debt service coverage
Net Revenue: (Revenues – Operating Expenses) Earn sufficient levels of net revenue to allow us to re-invest in our business, cover our debt service obligations, meet Rating Agency expectations and pay an appropriate city contribution.
Customer Expectations
• Do we meet our customers expectations in regards to cost, quality and customer service?o Focus Areas
Customer Service: Treat customers with respect, endeavor to meet their expectations and continually improve service levels
Price: Maintain a price structure that will ensure adequate income growth, provide high quality services, maintain fiscal responsibility and be competitive with benchmarked peers
Quality: Keep the electricity on, the water clean and pressurized, wastewater efficiently removed without cave-ins, blockages or odors.
Organizational Effectiveness
• Do we have the right people, the right skills and the right organizational design to accomplish the job?o Focus Areas
Workplace Environment: Continue to seek ways to provide the right environment that encourages high productivity, fosters adherence to our core values and makes employees partners in JEAs success
Workforce Readiness: Maintain a best-practices workforce by investing time and resources in right-sizing our workforce, succession planning, safety, health, technical and business training and by providing competitive compensation and benefits
Business Alignment: Align JEA’s culture, values, strategy, business structure, systems, processes, metrics, and performance management tools to meet our mission
Community Responsibility
• Do we do what’s right for our community?o Focus Areas
Environmental Stewardship: Demonstrate leadership by respecting the environment, promoting conservation and undertaking specific initiatives that exceed the requirements of targeted environmental laws and regulations
Growth Planning: Provide utility and infrastructure support for community growth and urban redevelopment assuring timely and adequate core services
Community Involvement: Find ways to improve the quality of life in the communities we serve both now and in the future

If we do not pay attention to all these areas, we end up with problems. Only focusing on satisfying the customer can result in keeping prices lower than needed, increasing debt to pay for infrastructure and less money to invest in our people

The Circle of Excellence
Jim Dickenson, James Chansler and Paul McElroy developed a visual illustration that represents the balance needed in our organization
At the center of ourbusiness is our
mission statement
To achieve ourmission, we mustbalance the four
strategic quadrants
Each quadrant consists of
three importantfocus areas

2007 Gaps
The EMT reviewed each of these areas and assessed the gap between current performance and desired performance in 2007. The biggest gaps were chosen as strategic focus areas
2008 Gaps
The EMT reviewed each of these areas and assessed the gap between current performance and desired performance in 2008. The biggest gaps were chosen as strategic focus areas
Strategic Focus Areas
• Customer Service• Electric Quality• Workforce Readiness• Environmental Sustainability
Customer Service
• Description: Customer Service is measured by direct customer surveys from three sources:o American Customer Service Index (ACSI)o MSI Modelo Customer Recontact Survey
• Goal: Improve ACSI score from 76 to 77.• Why: Customer Satisfaction around service (their
perception) is and remains a significant part of JEA’s mission and strategic plan; and JEA currently has a large negative gap in this area. We constantly need to provide a visible and positive value to our customers.
Electric Quality (SAIDI, SAIFI, SAIRFI)
• Description: JEA customers consistently rank us low and think we’re providing unreliable electric services—and some internal metrics match that assessment.
• Goal: The percent 9s and 10s metric on the electric reliability question from our customer survey is greater than 60% for residential customers and greater than 65% for commercial. Internal metrics (SAIFI, SAIFI-2, SARFI-80) are improved by at least 50%.
• Why: Customer Satisfaction around Quality (their perception) is and remains a significant part of JEA’s mission and strategic plan; and JEA currently has a large negative gap in this area. NERC Electric Reliability Standards are driving us in that direction. JEA needs to step out front and be seen as an industry leader (vs. being forced along). We constantly need to provide a visible and positive increase in value to our customers.
Workforce Readiness (Right Talent, Right Time, Right Place)
• Description: Ensuring we have the workforce that we need both now and in the future
• Goal: Develop and execute a plan to have a workforce that meets our current and future needs
• Why: Like most utilities, JEA is currently experiencing difficulty hiring qualified employees in certain positions. Recruiting and retaining quality employees will become more difficult in the future. JEA needs to plan and act on this issue now.
Environmental Sustainability (Meeting Future Requirements)
• Description: No consistent environmental policy/strategy utilized in planning for future growth across company.
• Goal: Environmental goals and plans are based on a philosophy of sustainability. At JEA, Environmental Sustainability means – a consideration of economic, environmental and social equity factors in all major decisions, but specifically as it relates to managing community growth.
• Why: We are moving toward a world in which resource use, emissions and discharge expectations are dramatically changing. Some communities in the U.S are already experiencing escalating requirements such as south Florida’s water constraints. There are also active discussions around limiting carbon dioxide (CO2) emissions, zero wastewater discharge and many other restrictions which could dramatically impact JEA.
What does this mean for me?
• Even though many employees in the company will be focused on these four strategic initiatives, not all employees will be involved
• We still need to ‘get the work done’ throughout the company (balanced focus)
• Continue to focus on what you are responsible for• Once the strategic plans are developed, be aware of the
plans and understand how your actions impact them• Participate on teams when requested
Training Goals
• This course will o Provide you with a 15 deliverable roadmap to solving
problems within the DMAGIC methodology Improving processes that operate on a routine basis
o Introduce you to Black Belt Six Sigma tools Individual tools are also used outside the DMAGIC
methodology to address various needs in day to day worko Help you become a leader for Process Improvement
