This sounds similar to what I was taught, in high school ~30 years ago, about journalism. When you write an article for the paper, the first sentence should have the who, what, when, where. The reader should be able to get the basic, relevant information from the first sentence then start giving more details as you go along. This is not only for the reader but to make it easier for the editor if/when they need to cut an article short then they can just cut text from the end.
