Outline
An outline is a prose telling of a story intended to be turned into a screenplay. It is generally longer and more detailed than a treatment but shorter and less detailed than a step outline.
Outlines are also written for research papers. They both help the writer to organize her ideas and a summary which shows the logical flow of the paper.
There are facetious versions of Martin Luther King's I have a dream speech written in outline form for a Microsoft Powerpoint presentation, which shows the gulf between an outline and the prose version of the concepts in an outline.
