The Rhetoric of Critical Procedures
One important aspect of technical writing is the production and use of procedures. Though technical writing serves a variety of purposes, teaching, informing, persuading, and even questioning, one of its primary and most common purposes is the 'how-to' function of providing procedures. There is a great deal of information available on writing procedures, the vast majority of it focusing on software documentation and product documentation.
