Technology can be intimidating to the general user. In fact, some have a fear of technology and want their company's IT support to hand-hold. Documentation that is accurate and easy to understand is essential to start users down the path to help themselves.
Having spent several years in computer support, I know computer technology, and I understand users. Classes at Carnegie Mellon University increased my understanding by introducing me to user testing and the theory of how interfaces affect user experience.
My experiences and skills extend beyond support and documentation to management. I have had success as a project manager because I understand the breadth and limitation of technology and how that meets the demands and needs of the user.
To me, a part of computer support is explaining to the user how to perform a task or avoid future pitfalls. Some problems may affect many users. Training addresses those problems. As the support person, I have identified areas that require training, developed a course syllabus, created instructional handouts, and taught users.
Writers need to understand the implications of audience and context when creating documentation. As an adjunct faculty at Point Park University, I develop courses that help students understand how to identify audience and context. Principles of grammar, style, and writing theory are integral to successful documentation. I explain the concepts to my students and stress their importance in successful professional or technical writing.
