This article describes a course design that offers an innovative approach to using client-based projects (CBPs) in technical and professional writing. It shows how teachers can incorporate CBPs in hybrid or fully virtual instruction, adapt it for a quarter or semester, and tailor it to meet students' needs. While there are standard writing assignments, such as letters, memos, progress reports, and job application materials, other writing activities assigned depend on the CBP. These projects can involve creating operation manuals, employee handbooks, event planning guides, rewriting gaming instructions, summarizing scientific reports, producing website content, and/or compiling annotated bibliographies. First, CBPs foster students' different talents and abilities and provide different ways to improve communication skills, allowing students to pursue their writing interests across a range of disciplines. Secondly, this course has broad enough goals to support CBP integration. This course was designed around three such broad goals: (1) composing in professionally appropriate modes; (2) understanding professional obligations and ethical behaviors in diverse situations; and (3) working individually and collaboratively. Finally, the learning objectives for each goal are flexible, thus providing both instructor and student with an open framework for pursuing client-based work.
