Root Cause analysis
Objectives

This course will enable participants to understand root cause analysis as a procedure for ascertaining and

  • analyzing
  • the causes of problems in an effort to determine what can be done to solve or prevent them. This course is designed to provide attendees with an in-depth understanding of how to analyze a system in order to identify the root causes of problems. This course will help enable you to:
  • Enhance problem-solving effectiveness by providing a model for in-depth analysis of problem situations.
  • Clarify the difference between analytical and creative thinking, and when each is most useful.
  • Promote the ability to provide problem-solving support in situations where one is not an expert in the process or technology involved.
  • Expand the range of tools available for analysis of problem situations.

Outlines

 

  • The difference between problem solving and root cause analysis
  • Why effective root cause analysis is more important in today\\\'s world
  • Some common problem solving models and their weaknesses
  • Five steps for performing the root cause analysis part of problem solving
  • What each step accomplishes and some tools available for carrying it out
  • Problem understanding
  • How the understanding step prevents working on the wrong problem and builds a base for later analyses
  • Different forms of flow diagrams for clarifying the process and interrelationships
  • Tools for priority setting (performance matrix, radar chart, critical incidents)
  • Requirements
  • Identifying possible cause generation and focusing
  • Why this step is critical to effective root cause determination
  • Different forms of brainstorming and the processes for carrying them out
  • Questions to ask when seeking possible causes
  • Other resources for possible cause ideas
  • Creative versus analytical thinking
  • Reducing the list through nominal group technique, multivoting, paired comparison, or matrix
  • Data collection
  • How this step avoids shotgun problem solving by identifying the most likely cause(s)
  • Population versus sampling; options for sampling
  • Check sheets and graphs for discrete data collection
  • Surveys, interviews and field observation for opinions or less precise data
  • Data analysis
  • Tools for discrete data analysis (run charts, histograms, pareto diagram, scatter diagram)
  • Tools for softer type data (affinity diagram, relationship digraph)
  • Technical versus organization problems, and analytical versus creative problems
  • Statistical tools for data analysis (z, t, & F tests; ANOVA, chi-square) and use of MS Excel
  • Cause and effect analysis
  • How this step links data analysis and possible causes
  • Tools for performing cause & effect analysis, such as cause & effect diagrams, structural diagrams, logic tree diagrams, matrix diagrams, and 5-whys
  • The importance of understanding the multiple cause, multiple effect chain
  • When to stop the analysis and return to the problem solving process
  • The rest of the problem-solving process
  • Identifying and selecting solutions
  • The importance of project management, and consideration of change management issues
  • Some models for understanding resistance and planning change
  • Implementation, follow-up, and standardization
