This is the correct order of the steps the team took during the Analyze Phase:
- Develop a Fishbone Diagram with the team
- Conduct a 5 Whys on likely causes
- Use data, observation or logic testing to verify causes
- State the Root Cause Hypotheses
- Conduct Data and Process Analysis
What are these steps?
Develop a Fishbone Diagram with the team: This is a visual tool that helps to identify and organize the potential causes of a problem. The team can brainstorm all of the possible causes and then categorize them into major categories.
Conduct a 5 Whys: This is a technique that helps to drill down to the root cause of a problem. It involves asking "why" five times to each of the potential causes identified in the Fishbone Diagram.
Use data, observation or logic testing to verify causes: Once the team has identified some potential root causes, they need to use data, observation, or logic testing to verify them. This may involve collecting new data, analyzing existing data, or observing the process itself.
State the Root Cause Hypotheses: Once the team has verified some root causes, they can state them as hypotheses. These hypotheses can then be tested further through additional data collection and analysis.
Conduct Data and Process Analysis: This step involves collecting and analyzing data about the problem. This data can be used to identify trends, patterns, and relationships that may help to explain the problem.
