ADVANCED PROBLEM SOLVING

A Systematic approach to root cause analysis

Course Description
This problem solving training course provides a clear and concise introduction to a systematic approach for clearly defining problems and identifying and verifying their root cause(s). It provides a step-by-step problem-solving methodology as well as an overview of the 8D (8 Discipline) problem-solving technique – and how to make future 8D investigations go more smoothly, quickly, and effectively. Participants will learn how to make their future problem investigations more valuable and meaningful for realizing cost savings and process improvement.

Learning Objectives
Unlike most courses on problem solving training, this workshop emphasizes that it’s not enough to be skilled in root cause analysis, 8D, 5 Why, and other techniques. One must connect his skill with knowledge – knowledge of theory of variation. In the face of one type of variation, systematic root cause analysis works like a hot knife through butter. In the face of another type of variation, deploy root cause analysis at your peril! The primary learning objective of this course is to help attendees to be guided by knowledge of theory while deploying problem-solving tools. Students will also develop skills necessary to:

  • Assure that a problem is well defined before considering possible causes of the problem
  • Test possible causes of a problem to determine whether or not they are likely causes
  • Verify true causes of problems before proceeding with corrective action
  • Integrate systematic root cause analysis into 8D, CAPA, and other standard procedures for problem-solving and root cause analysis
  • Distinguish between common causes and special causes of variation
  • Deploy systematic root cause analysis guided by knowledge of theory, thereby avoiding common and costly mistakes due to failure to distinguish between common cause and special cause variation
