The order, structure, or presentation is compelling and moves the reader through the text. An inviting introduction draws the reader in and a satisfying conclusion leaves the reader with a sense of resolution. Transitions are smooth and connect the information into a cohesive whole. Organization flows so smoothly the reader hardly thinks about it. The reader's understanding of the topic grows throughout the paper.
Pacing is very well controlled.
The writer delivers the needed information and then moves on. Sequencing is usually logical. It may sometimes be too obvious, or otherwise ineffective. The paper has a recognizable introduction and conclusion. Transitions often work well.
