ROOT CAUSE ANALYSIS
INTRODUCTION FOR ROOT CAUSE ANALYSIS
The natural tendency of many individuals and organizations when presented with a problem is to jump to a solution, any solution. They do not systematically analyze the problem to determine a root cause before considering potential solutions. This intensive 2 days Root Cause Analysis training is based on the proven Six Sigma performance improvement methodology with a strong focus on analyzing the root cause of problems and developing appropriate solutions. The course will start with the identification, prioritization and definition of problems. We will then consider how we measure the problem and then use logical, data and process analysis to understand the problem followed by root cause analysis tools. Once we have verified the root cause, we will then consider how we identify, evaluate, develop and implement a solution that addresses the root cause of the problem.
OBJECTIVE ROOT CAUSE ANALYSIS
- Method: To have an in-depth root cause analysis method. Provide a clear causal understanding of the event and can see the causal relationships. In a systematic, organized and clear in manner.
- Tools/process: Share technique/skill of asking questions and develop good sense of logical thinking process – questions to stimulate remembering not justification (5 Whys method, Logical Analysis tool etc.
- Actions: Develop corrective action that provide the strongest safeguard to future error. (Example:-how to ensure corrective actions of human related issues, e.g “Education/Displine/Procedure” effectively implemented)
Problem Identification process
- Roles and responsibilities
- Problem definition
Problem solving techniques
- DMAIC approach
- 8D approach
Measuring the problem
- Process and definition
- Sampling and collection Plan
Root cause analysis process
- Is/Is not analysis.
This approach allows the participants to ask the right questions in a systematic way. By answering these questions, you decide the scope of what you will examine and analyze, and what is not important or relevant enough to be a focus of attention at this time.
