Style guides, the primary tool of technical editors, are as important as ever; actually, their increased uses and benefits can redefine the activities of editors. Specifically, style guides can be used to train new employees, to generate buy-in of subject-matter experts, and to define the process flow of document and product generation. Additionally, because they have the potential to control many style decisions and to integrate a variety of skills, computer-driven styles and Web style guides reinforce these increased uses and benefits and suggest the emergence of even more. Thus technical editors' roles may be expanded to include additional training functions, new marketing dimensions, and innovative research in multimedia design and development.
