Graphics and Invention in Engineering Writing    

This study reports on the use of graphics by engineers as a method of stimulating the writing process (rhetorical invention). Information presented here comes from working engineers, based on a questionnaire developed after informal conversations and then administered to 15 participants in private industry, with questions about specific writing genres and types of graphics. Results show that graphics have a powerful function in stimulating writing ideas. Although individual writers' preferences in graphics are strong, patterns could be seen in (1) overall number of graphics types used by each writer, (2) specific types of graphics used by each writer based on the writing genre, and (3) the most common types of graphics used overall.
