Abstract:

Technical writers are often asked to write more than just end-user manuals or online help systems. Due to company size, layoffs, or a lack of resources, the technical writer might also be expected to deliver marketing communication collateral, Web site content, training materials, and more. These additional tasks can daunt those who have not been formally trained in other writing styles or those who do not switch writing styles easily.
