| 释义 |
An issue tree, also called logic tree, is a graphical breakdown of a question that dissects it into its different components vertically and that progresses into details as it reads to the right.[1]{{rp|47}} Issue trees are useful in problem solving to identify the root causes of a problem as well as to identify its potential solutions. They also provide a reference point to see how each piece fits into the whole picture of a problem.[2] According to professor of strategy Arnaud Chevallier, there are two types of issue trees: diagnostic ones and solution ones.[3] Diagnostic trees break down a "why" key question, identifying all the possible root causes for the problem. Solution trees break down a "how" key question, identifying all the possible alternatives to fix the problem. Four basic rules can help ensure that issue trees are optimal, according to Chevallier:[3]
The requirement for issue trees to be collectively exhaustive implies that divergent thinking is a critical skill.[4] See also
