LSS-104: Root Cause Analysis and Improving the Process

Loading Events
  • This event has passed.

One of the most important and challenging steps in a Lean Six Sigma improvement project is to determine the root cause(s) of problems within the project scope. Possible causes must be confirmed or debunked by data analysis. If there are multiple root causes, these should be prioritized. Once root causes have been identified, the next step is to develop and prioritize solutions. The best solution(s) are identified, tested, and then assessed to make sure that the intended outcome is achieved. The root cause analysis and process improvement is presented in this 2-day module. LSS-103: Measuring Process Performance-II must be taken before LSS-104: Root Cause Analysis and Improving the Process.

By the end of the course, participants will learn how to:

  • Describe the population associated with a process
  • Classify significance testing into two basic types: comparing populations, correlating variables
  • Explain P values and how they relate to standards of evidence
  • Test for differences between or among population
  • Test for correlations between variables and interpret the results
  • Perform root cause analysis
  • Use common solution categories to assist in developing solutions for your project
  • Use the results of root cause analysis to develop solutions for your project
  • Apply Lean solutions
  • Use benefit/feasibility analysis to evaluate proposed solutions
  • Apply FMEA to your proposed future state
  • Plan and conduct a pilot study of your future state process
  • Establish statistical baselines for your future state process
  • Test for significant improvements of the future state over the current state

Tools participants will learn:

  • Significance testing
  • Interpreting P values
  • Five whys
  • Affinity analysis
  • Fishbone diagram
  • Developing solutions
  • Lean solutions
  • Theory of Constraints
  • Failure Modes & Effects Analysis (FMEA)

Who Should Attend:
This course is designed for Engineers, Quality Analysts, Process Improvement Specialists, Program Managers, Project Leaders, and others who want to learn the Six Sigma Green Belt methodology and apply it to make breakthrough improvements in performance within their workplace.
