  • 1. Lean Six Sigma for Service by Michael L. George

2. Using Lean Six Sigma for Strategic Advantage in Service

  • Services have 30-80% waste
    • Activities that have no value to the customer
  • Service activities are not used to collecting and using data about their processes
  • Focus on how the customer perceives value instead of how we are arranged internally
  • Shift resources to where their impact is maximized

3. What is Lean?

  • Lean focuses on speed of execution
    • Velocity of a process is proportional to its flexibility
  • Maximize process velocity
    • Speed acceleration tools
  • Optimize work flow
    • Rapid action Kaizen teams
  • Eliminate delays
  • Quantify and eliminate complexity
    • The complexity of the service generally adds more nonvalue added costs than both poor quality or slow speed process problems
  • Eliminate non value added steps
  • 80% delays caused by 20% of the process steps

4. Indications of Fat

  • WIP backlog
  • Slow processes are expensive processes
  • Chasing information
  • Decision loops
  • Interruptions
  • Expediting necessary
  • Work lost in cracks
  • No visibility of overall process

5. Littles Law

  • Backlog ties up resources
  • Lead time= Work in Process/average completion rate
    • To increase efficiency, limit the amount of work you allow into the process
    • This works for materials, but not for face time with the customer
    • Pull system is good control mechanism
      • Cap at maximum WIP, create buffer, triage work coming out of the buffer as a pull

6. Process Efficiency

  • Process efficiency = value-add time/ total lead time
  • It qualifies how much opportunity exists
  • Track work items through system and create a time value map
    • Does that part of the process add value recognized by the customer?
  • Work to eliminate non value added sections
    • Less required waste for accounting, legal, or regulatory requirements

7. What is Six Sigma?

  • Six sigma focuses on accuracy
  • Recognize opportunities and eliminate defects based on customers value
  • Eliminate variation
  • Use statistical tools
  • Seek documented, repeatable processes
    • Infrastructure to support continued progress
    • Identification of customer critical to quality needs

8. Core Elements of Six Sigma

  • Management must be engaged
  • Allocate resources to high priority projects
  • Train everyone
  • Eliminate variation
    • Drives narrower bell curves
    • 99.9997% +/- 6 standard deviation from the mean

9. Invisible Work Cannot be Improved

  • Use a value stream analysis to diagram the process flow
    • Find time traps
  • Get agreement on areas of waste.
  • Establish ownership and create priorities.
  • Display priorities
  • Track and display daily performance
  • Manage expectations
    • Communicate
    • Provide feedback

Value is in the Eyes of the Customer

  • Customer critical to quality must haves are the highest priority for improvement
    • Next are ROIC and Net present value

12. Value Based Management

  • Price paid is a reflection of value to the customer
    • How well do your services meet the customers needs
    • What customer needs are you not meeting
    • What offerings have no value to customers
    • How do you compare to your competition
    • What are world-class levels of performance

13. Use VOC to Transform

  • Align your priorities to your customers
  • Transform customer needs into functional requirements and then into design requirements
    • Quality Function Deployment
    • Segment market, research market, analyze data
    • Repeat to refine understanding of customer needs
  • Define, measure, analyze, improve, control

14. The goal of VOC

  • Contribute at such a high level of service that our work promotes and fosters to continued advancement of the organizations mission

15. Lockheed Martin

  • Understand value from the customers prospective
  • Understand where product and service value are created in the organization (value stream)
  • Optimize for flow to get to optimal performance
  • Focus on cycle time and pull
    • Shrink process time to the minimum to speed response to customer changing needs
  • Achieve Six Sigma quality at lean speed

16. Rollout Challenges

  • Convince folks to devote time to LSS
  • Understand need for changes in layout
  • Sometimes lean changes required are counterintuitive to services
    • Reduce WIP
  • Translate LSS into lingo understood within workplace
  • Build an awareness of what waste looks like

17. Rollout hints

  • Give business units the credit
  • Tailor models to fit
  • Use a pace that fits organizational readiness
  • Dont force it on people generate pull
  • Solve problems cross functionally
  • Speed creates more noticeable improvements and quicker results
  • Data gathering and analysis takes time

18. Identifying Burning Platforms

  • Burning Platforms are your biggest competitive or strategic challenges
    • Here you will create shareholder (taxpayer) value
    • Represents your competitive advantage
    • Compare against world class
    • Do a value stream and compare value creation vs value destruction
    • Measure growth potential also
      • Compare investment required vs EV of payoff

19. Possible Actions

  • Shut down processes that destroy value, are unprofitable in the market, where competitors are advantaged
  • Invest to improve position of processes where you are competitively advantaged, even though you are currently destroying value and not getting a profit
    • Should be close to breakeven re economic profit

20. Comparing Opportunities

  • If you are value neutral, at economic breakeven, yet competitively disadvantaged, weigh the costs of removing waste to the potential EV of being more responsive to the customer
  • If you are competitively advantaged and creating value, just monitor to maintain market.
    • Not as critical to invest
    • Better opportunities in other value streams

21. Value added

  • The task adds a function or feature that the customer will pay for
  • The task provides you a competitive advantage (reduced price, faster delivery, better quality)
  • The customer prefers what we will produce over our competitors

22. Business Non Value Added

  • Gotta do these even though the customer will not pay for it
  • Required by law or regulation
  • Reduces financial risk
  • Financial reporting requirements
  • Critical to process stability

23. Non value Added

  • Rework, expediting. Multiple signatures, counting, handling, inspecting, setup, downtime, transporting, moving, delaying, storing
  • Create congestion, variation, complexity
  • Does not consume existing capacity while producing higher revenue

24. Create Time Delay Diagrams

  • Look for time traps
  • Look for build up in WIP
  • Consider what are the cost drivers/ failure modes
  • Evaluate cost to remove impediment vs expected value of improvement
  • Pareto chart is a good tool for comparing contributions of process corrections toward error rates


  • Use these tools to
  • Define: Value stream map, non value added analysis
  • Measure: Process cycle efficiency, process sizing
  • Analyze: Constraint identification, Time trap analysis, Queuing theory
  • Improve: Kaizen, Process flow improvement
  • Control:Visual control process

26. 5S = Improve

  • Straighten
  • Shine
  • Standardize
  • Sustain
  • Plus one Safety
