Six Sigma Six Sigma Overview Overview

  1. 1. Six Sigma Six Sigma / Lean (Using Data to Drive Decisions) (Using Data to Drive Decision) (Using Data to Drive Decision) (Changing to Excellence) Six Sigma Overview LEAN Michael Elias (Aiming for Perfection) Lean Deployment Leader (Working to Perfection)
  2. 2. Six Sigma / Lean Agenda (Using Data to Drive Decisions) NYGH’s Improvement System (one slide) Overview of Six Sigma Comparing & Contrasting Lean and Six Sigma (Working to Perfection)
  3. 3. Six Sigma / Lean The NYGH Improvement System (Using Data to Drive Decisions) The Effectiveness (E) of the result is equal to the Quality (Q) of the solution times the Acceptance (A) of the idea Q uality x A cceptance = E ffectiveness Lean Lean Six Sigma Change Effective Effective Six Sigma Change Methodology Management Results Results Methodology Management Project Management, PDSA Project Management, PDSA A proven formula for results A proven formula for results (Working to Perfection) GE Medical Systems Performance Solutions, General Electric Co. 2003 Norman R. F. Maier, The Journal of Applied Behavioral Science, Vol. 1, No. 4, 373-386 (1965)
  4. 4. Six Sigma / Lean The “A” Side of The Equation (Using Data to Drive Decisions) Q uality x A cceptance = E ffectiveness Change Management Creating a Shared Need Mobilizing Commitment? Changing Culture and Structure? (Working to Perfection)
  5. 5. Six Sigma / Lean The “A” Side of The Equation (Using Data to Drive Decisions) Leading Change Creating A Shared Need Shaping A Vision Mobilizing Commitment Current Transition Improved State State State Making Change Last Monitoring Progress Changing Systems & Structures (Working to Perfection) Change Acceleration Process, GE Medical Systems Performance Solutions, General Electric Co. 2003
  6. 6. Six Sigma / Lean The “Q” Side of The Equation (Using Data to Drive Decisions) Q uality x A cceptance = E ffectiveness Six Sigma What is Six Sigma? What’s the Goal? What’s the Impact on Culture? (Working to Perfection)
  7. 7. Six Sigma / Lean Six Sigma: New or Old? (Using Data to Drive Decisions) As Old as Science How Old Is Science? Really Old (Working to Perfection)
  8. 8. Six Sigma / Lean Six Sigma is.. (Using Data to Drive Decisions) ..an exercise in the scientific method Attributes Include: • Hypothesizing • Observing • Statistical Correlations • Measurable Evidence • Experimentation/Testing • Formulation of Theories (Working to Perfection)
  9. 9. Six Sigma / Lean Side By Side (Using Data to Drive Decisions) Scientific Method Six Sigma (DMAIC) Define Determine what the customer values as Critical to Quality. Measure Establish a method for measuring those things that impact those things critical to quality Analyze Determine how far the gap is between what the patient wants and what the process is able to provide. Improve Work on the right problem and meand the gap. Control Ensure that the gap never occurs again (Working to Perfection)
  10. 10. Six Sigma / Lean Six Sigma: Philosophy (Using Data to Drive Decisions) Measure of Quality: Six Sigma is a statistical measure expressing how close a service comes to meeting it’s quality goals The Goal: To achieve superior quality •Quantitatively, this means that the average process generates less than 3.4 defects per million opportunities. Culturally: This means we need to learn how to be nearly flawless in executing our key processes (Working to Perfection)
  11. 11. Six Sigma / Lean (Using Data to Drive Decisions) Six Sigma as it applies to Happy Marriage Wife = Customer (Working to Perfection)
  12. 12. Six Sigma / Lean (Using Data to Drive Decisions) Customer Specification Lower Mean Mean Upper Customer Customer Specification Specification Wife so Wife Wife Happy Divorces Content & She Can’t Husband Happy Think Straight Not So Happy Too Happy Happy Wife (Working to Perfection)
  13. 13. Six Sigma / Lean (Using Data to Drive Decisions) Plot The Bell Curve Every Human Activity Has Variability... Lower Mean Mean Upper Customer Customer Specification Specification Wife so Wife Happy She Divorces Can’t Think Husband Straight Not So Good Too Good Good Enough (Working to Perfection)
  14. 14. Six Sigma / Lean (Using Data to Drive Decisions) The Basic Idea of Six Sigma Attack and Eliminate The Variation... Squeeze Mean Mean Squeeze Wife Wife so Happy Divorces She Can’t Think Husband Straight -9 -8 -7 -6 -5 -4 -3 -2 -1 -9 -8 -7 -6 -5 -4 -3 -2 -1 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 Reducing variability is the essence of Six Sigma Reducing variability is the essence of Six Sigma (Working to Perfection)
  15. 15. Six Sigma / Lean (Using Data to Drive Decisions) A “6 Sigma” Process What does it mean to have a 6 Sigma process? Mean Mean It means that my wife is willing to accept 3.4 mistakes per MILLION CHANCES -6 -5 -4 -3 -2 -1 -6 -5 -4 -3 -2 -1 1 2 3 4 5 6 1 2 3 4 5 6 (Working to Perfection)
  16. 16. Six Sigma / Lean What is a Six Sigma Project? (Using Data to Drive Decisions) • Addresses an important business objective • Data driven • Team drives the project • Black Belt leads the team and acts as a Six Sigma Technical Resource • Average time to completion 4 months to 1 year Large and Complex Undertaking Large and Complex Undertaking (Working to Perfection)
  17. 17. Six Sigma / Lean Agenda (Using Data to Drive Decisions) Side By Side Comparison (Working to Perfection)
  18. 18. Six Sigma / Lean Lean & Six Sigma (Using Data to Drive Decisions) Fusing Lean and Six Sigma is Required for Two Reasons…. 1) Lean does not address bringing a process under statistical control Speed Oriented 2) Six Sigma cannot, alone address improving the speed of process Quality Oriented (Working to Perfection) George, L Michael: Lean Six Sigma, McGraw-Hill: 2002
  19. 19. Six Sigma / Lean Integrating Lean Into The Six Sigma (Using Data to Drive Decisions) Six Sigma Define Determine what the customer values as Critical to Quality. Use Lean Tools to Measure Accelerate Establish a method for measuring those Improvement and to things that impact those things critical to Manage Change quality Analyze Determine how far the gap is between what the patient wants and what the process is able to provide. Improve Work on the right problem and Use Kaizen To Deliver Improvements meand the gap. Control Ensure that the gap never occurs Use Visual Control System again (Working to Perfection)
  20. 20. Six Sigma / Lean Integrating Six Sigma Into Lean (Using Data to Drive Decisions) Preparation Kaizen Follow-up 3 Weeks 1 Week 3 Weeks Define Voice of the Customer. CTQ’s CTQ’ Measure Control Conduct MSA’s, strive for rep sample size MSA’ Statistical Process Control Analyze Look for statistical correlations & variation (Working to Perfection)
  21. 21. Six Sigma / Lean Lean and Six Sigma (Using Data to Drive Decisions) Six Sigma Lean Goal Identifies and eliminates complex Eliminates simpler sources of sources of variability variability and creates flow by eliminating waste Targets 85%--90% 20%-50% Application Where statistical process control is Where standard work is needed needed Approach Expert Driven- requires thorough Front Line Driven-Utilizing the understanding of experimental design collective wisdom of point of care and applied statistics staff with Lean expertise guiding Project Selection Source of the variation is unknown Driven by value stream map No predetermined solutions exist Length of 4 months to 1year 1 week to 3 months Projects Training Technical classroom training/learn by Learn by doing doing (Working to Perfection)
  22. 22. Six Sigma / Lean Operational Improvement (Using Data to Drive Decisions) +σ 6σ Six Sigma 5σ 4σ Lean Six Sigma 3σ 2σ Lean 1σ PDSAs, Project Management 0σ -σ Leadership Decisions As scope and complexity increases, the tactics shift from Lean to Six Sigma (Working to Perfection)
