Strategic organization is putting a speech together in a particular way to achieve a particular result with a particular audience.

Main points are developed in the body of a speech. Most speeches contain from two to five main points.

Strategic order of main points depend on three things

* Topic
* Purpose
* Audience
This is in chapter 8.

So it is true.

Every speech depends on both on the topic and it's specific purpose but may not depend on the audience it also depends on how good you make it and does not bore others!!
