The Pyramid Principle, developed by former McKinsey consultant Barbara Minto in the 1970s, is a communication framework for structuring arguments in a clear, top-down, and logical manner. Instead of saving the main point for the end, the principle advises starting with the answer and then providing the supporting details. This approach is particularly effective for presenting complex information to busy executives who need to grasp the most important takeaway immediately. The principle is based on three main components arranged in a pyramid shape:  - **Top: The main point or assertion**. This is the key takeaway, conclusion, or recommendation. It is the most important piece of information that the audience needs to know and summarizes all the points below it. - **Middle: Supporting arguments**. The next level down consists of the main points that support the top-level assertion. These are the "because" statements that explain why the conclusion is true. - **Bottom: Supporting data**. The lowest level provides the detailed data, evidence, and facts that prove the validity of the supporting arguments.
