Trees have to be mece to avoid inefficient dependencies between branches. Use hypotheses when analyzing your issue tree to come quickly to the root cause. Be sure to differentiate two types of issue trees problem based or solution based.
An issue tree is the most important tool for structuring your case and form hypotheses. With root cause analysis your goal is to uncover all potential root causes but the universe of root causes is limited whereas the universe in an issue tree is wider and more. This is not like root cause analysis because the point of an issue tree is to uncover all potential possibilities.
It s a silly example but you get the point. It almost feels it was put together mindlessly as if actually solving the problem wasn t a concern in the candidate s mind. Now here s an example of a mece issue tree for the same problem that isn t built with enough skill.
Then in the next level of this issue tree you may want to include the driver of product differentiation from competitors. For example in the first level of the issue tree one branch may be competitors and another branch may be product. I find it difficult to truly make my branches mutually exclusive.
In this post we cover issue tree examples and templates you can reuse in your own case interviews. Mece issue trees aka logic trees are used to break down complex questions into simpler sub questions. Issue tree analysis is used by mckinsey and other consulting firms to solve client problems.
In the example of the issue tree given. If you manage to get a position at mckinsey or at any other mbb for that matter you are likely to have to handle huge amounts of data. Mece framework mckinsey mece pronounced me see an acronym for mutually exclusive and collectively exhaustive is a popular mantra at mckinsey.
Subsequently an issue tree like format is used to break down the estimation into its basic components for easier approximation of data.

Issue trees start with the problem statement and break it down into its component parts issues and sub issues.
They are favored at mckinsey because they 1 break problems down into manageable parts 2 enable solving the larger problem by solving the component parts 3 align the team on the nature of the problem and how to solve it and 4 provide insight into missing elements. Issue trees also known as logic trees and hypothesis trees are the most fundamental tool to structure and solve problems in a systematic way. Mastering them is a requirement if you want to get a job in a top consulting firm such as mckinsey bain and bcg. The example below from the startup vs.
Consulting case on preplounge shows how costs are typically broken down in a mece way.
