Two Approaches to Modularity: Comparing the STOP Approach with Structured Writing 
The first time I heard of the STOP paper was sometime in the mid 80's when the historian of technical writing, John Brockman, phoned me to ask if my Information Mapping method of structured writing derived from the STOP method. At the time I told Brockman that there was no direct relationship between our two approaches since I'd never read the paper. When the editor of this journal sent me the STOP document in preparation for writing this paper, I read it with delight. Although our two innovations date from the same period, the STOP authors and I were working in two completely different disciplines, cultures, organizations, and locations. These two approaches resulted in modularity - albeit of quite different kinds. The main purpose of this project is to compare and contrast these two approaches to modularity. I should note here that I approach this article principally as an exercise in historical comparison, rather than as an exposition of my current views, about which I will say a bit at the end of this article.
