Three organizational patterns that are particularly useful for informative speaking are topical, chronological, and spatial. As you’ll recall, to organize a speech topically, you break a larger topic down into logical subdivisions. An informative speech about labor unions could focus on unions in three different areas of employment, three historically significant strikes, or three significant legal/legislative decisions. Speeches organized chronologically trace the development of a topic or overview the steps in a process. An informative speech could trace the rise of the economic crisis in Greece or explain the steps in creating a home compost pile. Speeches organized spatially convey the layout or physical characteristics of a location or concept. An informative speech about the layout of a fire station or an astrology wheel would follow a spatial organization pattern.
