# Problem Solving, the McKinsey Way

The McKinsey Mind explains how McKinsey & Co. use a fact-based method of problem solving based on the following steps. The following is my interpretation of these steps:

**What’s the problem?**Identifying and isolating the core problem, which is usually based on a competitive, organizational, financial, or operational need.- Use a mutually exclusive, collectively exhaustive (MECE) approach to identify non-overlapping boundaries of the problem.
- Break the problem down using logic trees (Visio would be great here) to show relations between components of the problem.

**What’s**Suggest a hypothesis for a solution to the problem, which will help guide your data gathering and analysis.*probably*the solution?**Analyze the data behind the problem.**Determine what analysis is needed to prove the hypothesis, and just as important, determine what you do not need to do.- Gather the data required for the analysis.
- Analyze the data to prove or disprove the hypothesis. If the facts disprove your hypothesis, change your hypothesis. In other words, let the data analysis drive the solution.

**Present the solution.**If the proposed solution is bought off by whomever you are presenting it to, then the work of implementing the solution starts.
