Efforts to improve the quality of business communication often include developing tailor-made short courses that are offered "in-house" to corporation management personnel. These following guidelines, based on one corporate writing teacher's experiences, should help others to develop writing courses for businesses: obtain samples of the types of writing actually produced by company personnel in order to locate strengths and weaknesses; develop a small manual of grammar and style that executives can use for quick and easy reference (regular textbooks would be too unwieldy and comprehensive for such courses); focus the manual on recognition of complete sentences, punctuation that prevents misinterpretation, effective sentence interrelationships and paragraph transitions, and a unified policy on matters of form; and develop a rationale for rating "students" in the program, taking into account each student's writing proficiency prior to and after taking the course.
