1 Who is Using Six Sigma in the Twin Cities
Seagate, Medtronic, Donalson, Honeywell, American Express, Ceridian, 3M

2 What is Six Sigma? Six Sigma - The Initiative Process Systematic approach to reducing defects which affect what is important to the customer Tools Qualitative, statistical and instructional Devices for “observing” process variables and their relationships as well as “managing” their character

3 Six Sigma - Aggressive Goal
PPM Process Capability Defects per Million Opp. Sigma is a statistical unit of measure that reflects process capability. The sigma scale of measure is perfectly correlated to such characteristics as defects-per-unit, parts-per-million defective, and the probability of a failure/error.

4 Six Sigma -- Practical Meaning
% Good (6 Sigma) 20,000 lost articles of mail per hour Unsafe drinking water for almost 15 minutes each day 5,000 incorrect surgical operations per week Two short or long landings at most major airports each day 200,000 wrong drug prescriptions each year No electricity for almost seven hours each month Seven articles lost per hour One unsafe minute every seven months 1.7 incorrect operations per week One short or long landing every five years 68 wrong prescriptions per year One hour without electricity every 34 years 99% Good (3.8 Sigma)

5 How Does Six Sigma Make the Difference?

12 Six Sigma - Why? To deal with a world of declining product prices
To compete successfully with the best companies in the world To establish standard language and approaches across functions and across businesses To develop our next generation of leaders To accelerate our rate of quality and productivity improvement faster than our competitors

13 Six Sigma Basics ...What If...?
That Is Six Sigma ! You Could Select One of Your Most Highly Leveraged Problems ? Identify One of Your Best People to Work on It ? Provide That Person With All of the Training, Tools, and Resources They Need to Fix It ? Guarantee Them Uninterrupted Time and Focus to Work on It ? And Get a Well Thought Out, Data Driven Solution ?

14 The People Who Make it Happen
DFSS Employees Green Belts & All Employees Business Champions Hands on Champions Six Sigma Directors & Six Sigma Executive Finance Reps Master Black Belts Black Belts

15 Six Sigma - Approaches to Improvement
Breakthrough Strategy Continuous Improvement -Trained & Dedicated Individuals -Analytical Expertise ->70% Improvement per Project -Current Tools -Kaizen -Lean Manufacturing -Reengineering -Typical TQM Time in Years 1 2 3 4 5 The problem with continuous improvement as the only goal…. Organization sees improvement BUT loses the game. Six Sigma Enables Breakthrough Level Improvement!

16 Focus on X rather than Y, as done historically
The Focus of Six Sigma KPIV(s) Y= f (X) KPOV(s) Focus on X rather than Y, as done historically Metrics KPOV = Key Process Output Variable KPIV = Key Process Input Variable Defect (Gap) Critical To The Customer *

17 Six Sigma as a Problem Solving System
Six Sigma employs the Breakthrough Strategy, which is a multi-step problem solving and process improvement methodology. 1. Measure 2. Analyze 3. Improve 4. Control 0. Define 5. Realize

Define the Situation Generates/Determines Create with Team with team Root Causes Strong Links Check Gauges & Data Collection Devices & Procedures Define/Measure Rolled Throughput Yield Determine: opportunities for improvement Defect Rate per Step

19 Six Sigma Road Map - Measure & Analyze
Generates/Determines Gather Historical Data or Sample (Size & Subgroup) Indicators: Performance & Entitlement DPMO; Sigma Score Cp Pp Cpk Ppk Process Capability Study Measure Determine Cost of Quality Review Internal & External Costs Potential Benefits Analytical Tools Trends & Behaviors in KPIV/KPOV relationships Minitab Analyze Confidence Intervals Applies throughout

20 Six Sigma Road Map - Analyze
Generates/Determines Answers: Difference in Means? One Pop. to Another; Before/After; to Spec Hypothesis for Variables - Means (t-tests) Variables Data Hypotheses for Variables - Std. Dev. (Chi Sq., F-Test, Homogeneity of Variance) Answers: Difference in Spread? One Pop. to another; to baseline; multiple Pops. Variables Data Analyze Answers: Differences in % Def. Between pop.; Diff. in % Def. from overall mean Hypotheses for Attributes (Contingency Tables, Non-parametric study) Proportion Defects Proportion Defectives Collecting data on several variables at the same time Points to variables warranting further analyses Multi-Vari Studies

21 Six Sigma Road Map - Analyze
Generates/Determines Variables Data Answers: Difference in Means? One Variable (Factor) Multiple Types ANOVA Analyze For pairs of continuous Data Variables Correlation & Regression Answers: If know X; Predict Y Strength & Direction This completes the Characterize phase confirming which Input Variables most directly affect the Output Variables: Move on to Optimize - Settings or Procedures

22 Six Sigma Road Map - Improve
Generates/Determines Known Relationships between KPIVs & KPOVs Design of Experiment Answers: How to Set “X” to get Best “Y” Answers: What’s the Best Combination of the “Xs’ for producing the Best “Y” Testing Variables at 2 Levels (High/Low) Full Factorial Simple 2K Improve Tests Multiple Variables, at Various Levels (High/Low) Answers: What’s the Best Combination of ALL Variables (X) to give the Best Output (Y) Full Factorial Multiple Variables Answers: Same as Above - But . .. Less Information; More Risk - but, requires less experimentation Tests Multiple Variables But Not All; Not All Levels Conserves Resources Fractional Factorial

23 Six Sigma Road Map - Improve

No Re-Design

26 Provide Intense Training
Six Sigma - How Does It Work? Select the Right People Provide Intense Training Select Key Problem Areas Assign Projects to Black Belts Obtain Results Champions Master BB’s Black Belts Brown Belts Strong Analytical Skills Strong Problem Solving Skills People & Leadership Skills Critical to Success Chronic or Systemic Fastest or Largest Return Lead Focused Effort Apply Skills and Tools Determine Causes and Solutions Reduce Variability Preventative & Proactive Vs Appraisal & Reaction Fewer Trials Faster Accurate Solutions

27 Six Sigma Basics Six Sigma Provides a Disciplined Method for Reducing Defects. Customers Define Their Critical to Satisfaction Measures (CTS’s). Champions Define Key Outputs of a Process Whose Defects Most Significantly Impact the CTS’s & Assign Projects to Black/Green Belts. Black/Green Belts Identify the Process Inputs That Most Significantly Influence the Outputs. They Then Eliminate the Root Causes of Variation in the Inputs and Put in Controls to Prevent Reoccurrence of the Problem. Design For Six Sigma Engineers Identify and Exploit Areas of Decreased Sensitivity to the Input Variables in Order to “Design In” Quality.
