This article examines a manageable approach that provides students with significant opportunities to write and improve their writing over time in an introductory quantitative business course. The study examines six elements of written communication skills, as evidenced by assessment data from memorandum assignments administered following pedagogical interventions throughout the semester in an operations management course. Results demonstrate that student performance of audience identification, action-oriented request, and punctuation improved. Interestingly, student performance of grammar slightly decreased. A follow-up analysis indicates that some writing mistakes were related to a lack of proofreading. This article also presents original memorandum assignments and suggestions for improvement.
