Demystifying Lean Six Sigma:Why the emphasis onContinuous Process Improvement?Vance A. Kinsey, CPTLSS Master Black Belt Presentation to ASQ Chapter Meeting 15 April 2009
My Journey • Scientific & Engineering Interest/Aptitude • Trainer….but training was not the answer • Supervisor/Manager….discovered the “system” (Good people, bad system—who wins?) • Education….Adult Learning ….but education was not the answer • Consulting….helping others achieve their goals • Human Performance Technology….CPT (people) • Lean Six Sigma….MBB (process) • Leadership….Strategic Transformation; helping organizations discover/achieve their goals
Agenda Why address process improvement History of Process Improvement--beginnings of the three basic principlesUnderlying principles of Lean, Six Sigma and Theory of Constraints including tools and techniquesRoles and Responsibilities/Certifications and Standards of LSS/CPI practitioners Deployment Strategies to integrate the practices successfully into an organization
WIIFM? As a Quality Professional, why am I concerned about Lean Six Sigma and/or Continuous Process Improvement? Is it a threat or an opportunity? And what is it anyway?
Managing Expectations—Project Nightmare How the customer explained it How the project leader understood it How the programmer wrote it How the consultant described it How the analyst designed it What was installed by operations How the customer was billed How the project was supported What the customer really needed How the project was documented
We don’t manufacture anything! We’ve already done this! How many of you have heard…? I don’t like it! Isn’t this another “flavor of the month”? We’re too busy!!! We don’t have the money!!!!! NEWS FLASH: ALL OF THESE THOUGHTS ARE NORMAL! We’re different! Our leaders won’t support it! How can I impact a command-level process? We don’t have processes! It’ll never work here! We’re not broke; we don’t need fixing!!!! I don’t want it here! Our processes only happen “on demand” I don’t want it!
PERFORMANCE IMPROVEMENT REFERENCE LIBRARY CPI/LSS has “borrowed” best practices from all of these initiatives
CPI/LSS is… Rigorous adherence to proven methodologies, tools and techniques that will enable a leader to confidently solve process problems using data-driven approaches so that the problems stay solved.
CPI/LSS is NOT… • Another management program. • A justification for buying new equipment, spending more money, or hiring/firing people. It IS a scalable collaborative process to capture, prioritize and address all concerns of customers, suppliers and stakeholders. It IS a philosophy to address and correct problems. It IS a low-cost approach to identify and implement appropriate changes to meet specific goals. It DOES require supervisors, managers and leaders to make good decisions. • A substitute for good leadership. • A “one-size fits all” solution.
Why now? We’re still the best, most advanced and most productive economy in the world, so… • Why is process change important now? • What is the “burning platform”? • Who is championing the need for change and why?
Why Lean Six Sigma as our CPI model? • Common language • Common practice • Shareable resources, personnel • Used by business & industry, government & military, and academia (including their consultants) • Benefits can be compared and collected • Rigorous, standardized training and certification process
Appropriate methodology for all types of processes Examples of areas that can be significantly improved: • Transactional/administrative process (takes too long) • Personnel overworked; multiple unnecessary steps (wasteful) • Document review process (inconsistent) • Unhappy customers & workers • Cuts, shortfalls, and downsizing • Ineffective management controls; inspections, oversight, surveillances, audits, reviews • Changing customer demand

History of Lean, Six Sigma, & TOC • Roots of Lean: back to early 1900’s • Henry Ford: continuous flow production, waste elimination • TWI: (Training Within Industry), 1940-1945 • Kiichiro Toyoda and Taiichi Ohno: low inventories, flexibility & responsiveness • U.S. supermarkets: pull systems • Shigeo Shingo: mistake proofing, reduced set up times (SMED) • Toyota Production System • MIT and James Womack: brought Lean back to U.S. • Eli Goldratt: published book “The Goal”, early 1980’s (TOC) • Motorola & others: developed Six Sigma early 1990’s NIKE

Where to use CPI/LSS for Problem Solving This is where CPI/LSS Works best. LEADERSHIP & ACCOUNTABILITY PROCESS PERSONNEL PLANT
Lean Principles • Specify “Value” from the Customer’s Perspective • Map & Analyze the “Value Streams” • Make the Value Streams “Flow” • Enable the Customer to “Pull” Value from the Value Streams • Seek “Perfection”
Lean is eliminating waste T I M W O O D U Under-utilization Of Employees Transportation Overproduction Non-Value Add Hauling EightWastes Motion Waiting Defects Over-processing Inventory
= Non-Value-Added Time (WASTE) = Value-Added Time The Value of Time Within the 8 wastes, time is a significant factor. Disassemble Transport Wait Re-Install Machine Machine Remove From Ship Set-up Inspect Transport BEFORE ANALYSIS Start Finish Broken Component Repaired Component TIME Value-added time is only a very small %of the total time. AFTER IMPROVEMENTS
Lean Focus Make all of the Value Stream visible Reduce or eliminate Non-Value-Added portions of the process Result: Large time savings Traditional Focus Improve Value-Added work steps Better tools, machines, instructions Result: Small time savings Time Amount of Time Eliminated The Value of Time Small LARGE amount of time saved Note: The focus is not on the value-added steps or the people performing them. Instead, the focus is to remove barriers and better support the people doing the work!
Shift Happens Six Sigma is eliminating variation “In God we trust, everyone else bring data.” Based on Statistical Thinking • All work is a series of process • All processes have variation • Businesses improve when they reduce or eliminate variation Process B Process A
What’s the big deal? Hey, 99% is good enough right? • 20,000 lost postal mail items per hour • 15 minutes of unsafe drinking water per day • 2 long/short landings per day at a major airport • 5,000 incorrect surgical operations per week • 7 hours of lost electricity per month • 20,000 incorrect prescriptions per month 99% 99.99966% (6 Sigma) • 7 lost postal mail items per hour • 1 unsafe minute every seven months • 1 long/short landing every five years • 1.7 incorrect operations per week • 1 hour without electricity every 34 years • 68 wrong prescriptions per year
TOC is eliminating bottlenecks • “The slowest vehicle in a convoy sets the pace” A constraint is anything in an organization that limits it from moving forward or achieving its goal When the constraint (critical path) is not progressing, the process is not progressing! If 100 people worked to improve 100 different processes, the 1 person working on the constraint process would save the organization much more than all the other 99 people combined! ---RESOURCE THIS FIRST---
