How does one go about organizing speech material in an orderly sequence?

Categorical/Topical. By far the most common pattern for organizing a speech is by categories or topics.

Comparison/Contrast. Another method for organizing main points is the comparison/contrast speech pattern.

Spatial. The spatial speech pattern organizes information according to how things fit together in physical space.

Chronological. The chronological speech pattern places the main idea in the time order in which items appear—whether backward or forward.

Biographical. As you might guess, the biographical speech pattern is generally used when a speaker wants to describe a person’s life—either a speaker’s own life, the life of someone they know personally, or the life of a famous person.
