Although different writing courses exist because of the different forms and purposes of writing they teach, some continuity between composition and business/technical communication would allow students to move more readily from one course to the next, while clarifying for them that writing is primarily a system of options based on analyses of situations, readers, obstacles, and goals. In this article, I call for that kind of continuity not only in pedagogy but also in research. Explaining the value of connections in pedagogy and research between composition and professional communication studies, I conclude with various questions and avenues for further research.
