How to read it
- Start with the main problem at the head of the diagram.
- Branch out to identify categories of causes, then detail specific causes under each category.
What this does
Identifies the underlying causes of a problem by visually mapping out potential factors and their relationships.
When to use it
Use it when a team needs to understand the root causes of a specific problem to address it effectively.
Not when: Do not use it when the problem is straightforward or when immediate solutions are required without deeper analysis.
What happens next
Consider using a Fishbone Diagram for a more structured approach to cause analysis.
