As a management consultant (or a scientist) you had to crack a very difficult issue: what approach to take to solve a particular problem or get to some insight. Once the approach was nailed, the rest of the work was relatively easy (sweat work rather than think work).

It is tempting to use this thought process as a structure of your presentation. Here is the problem, here is the theory behind it, here is our methodology, here is the data analysis, and finally, here is the conclusion. Most scientific papers are structured this way and kids get taught this approach in school/university.

This works if your audience also consists of management consultants and scientists. In most other cases, just talk about the problem you tried to solve (the actual one, not the approach issue) and then go straight to the conclusion and results.
