Relation diagram
Purpose
To illustrate the relationship between problems and ideas in complex
situations. Also to identify meaningful categories from a mass of ideas
when relationships are difficult to determine.
When to use
When a topic is so complicated that relations between different ideas
cannot be established through conventional reasoning and the problem in
question is exclusively a symptom of a more fundamental underlying
problem.
How to use
The development of the relation diagram should be conducted in teams.
The team writes each idea in a circle and clusters the circles in proximity to
each other. It then identifies which idea strongly influences another and
uses arrows to indicate the direction of influence. The results are evaluated
by identifying ideas that have the most arrows entering or exiting.
