  • 1. Root Cause Analysis
  • 2. Root Cause Analysis
    • “ Problem, a question proposed for solution”.
    • “ A problem is a state of difficulty that needs to be resolved”.
    • Beneath every problem lies a cause for that problem. Therefore, when trying
    • To solve a problem, consider this approach:
    • Identify the cause (or causes) of the problem.
    • Find ways to eliminate these causes and prevent them from recurring.
  • 3. Root Cause Analysis
    • Definition: Root Cause Analysis is a structured investigation that
    • aims to identify the true cause of a problem, and the
    • actions necessary to eliminate it.
    • Purpose: To identify the problem and using robust methods of
    • investigations, find the true cause or causes of the
    • problem. Once the true cause has been identified,
    • corrective action can then be applied.
    • Scope: All applications.
    • Process: Identify the cross functional team.
    • Identify the problem.
    • Investigate the best cause analysis to be used.
    • Select the tools for the analysis.
    • Conclusion of the analysis.
  • 4. Process:
    • Identify the cross functional team:
    • One person cannot identify all the possible causes of a problem.
    • Select those people directly involved in the application, set up and design.
    • Select those people who will participate in the investigation and give valid input.
    • Designate a responsible leader for the team to report status and timing.
    • Facilitate the team's needs when needed.
  • 5. Process:
    • Identify the problem.
    • Eliminate all possibilities.
    • Gather all facts to the problem to include time, dates, data, inventories, etc.
    • Document the problem and the related facts on a chart that can be used in the cause analysis.
  • 6. Process:
    • After identifying the problem, select the best method or analysis to use.
    • There are many methods of analysis but all may not apply to a certain cause.
    • Pareto analysis is good for multiple characteristic causes.
    • Brainstorming analysis can be used to determine multiple problems in a system or environment causing the one ultimate cause.
    • Histograms can be used for evaluating data in a time frame.
    • These are just a few examples of the different analysis to be used in investigations and evaluations.
  • 7. Examples of analysis: Pareto
    • 60%
    • 50%
    • 40%
    • 30%
    • 20%
  • 8. Examples of analysis: Brainstorm
    • Manpower Methods
    • Sort Failure
    • Transportation Environment

  • 10. Process:
    • Select the right tools.
    • Define the investigation.
    • Know your evaluation method.
    • Determine the course of the study and stick with it.
    • Apply the information from the team to the tools used for the best evaluation.
    • Use more than one tool if necessary to get most information.
  • 11. Process:
    • Conclusion from the analysis.
    • Don’t be satisfied until the evaluation is complete.
    • The final cause is clear.
    • Be able to define and defend your analysis. Documentation is everything.
    • The analysis should lead or point to a direct path for resolution.
