For a general introduction to cause mapping, see root-cause-analysis.php.
Most cause maps deal with some problem. This cause map is different in that the
primary effect on the left is to be desired rather than avoided. In the above
cause map, the student graduated in the top 10% of his class and we are asking
why this happened. The primary effect is shown on the left in red. Color is not necessary in
cause mapping, but it is helpful to highlight the main effect.
You read this chart from left to right and add the words "was caused
by" at each line. For example, "Student valued learning" was caused
by "Genetic disposition to succeed" and/or "Peers valued
intelligence" and/or "Parents supported students interests"
and/or "Sibling rivalry."
