Often it makes sense to organize your points according to time: what happened first, second, and so on. A chronological pattern presents the main points of a message forward (or backward) in a systematic, time-related fashion. For example, you might use a chronological presentation when speaking about the development of Picasso’s style over the course of his life. A chronological organization can be especially effective when analyzing a step-by-step process, such as a presentation on the stages of grief or how to use a particular smartphone application.
