I am technical writer and as such I can answer the question. Technical writers are important because of the gap in knowledge between a technical professional and an end user. A good technical writer can work with a subject matter expert, then use words and images to communicate technical information to an end user who needs to use the information in an applied manner. Unfortunately, technical managers often incorrectly assume they do not need technical writers and/or can do this work themselves. If generating high-quality, useful technical documentation is your objective, hire an experienced technical writer who has that unique combination of technical knowledge, listening skills, written communication skills, and applications skills (e.g., Microsoft Word, Adobe Framemaker).
