Overview

Technical writing is performed by a technical writer and is the process of writing and sharing information in a professional setting. A technical writer’s main task is to convey information to another person or party in the most clear and effective manner possible. The information that technical writers convey is often complex, and it is one of their main tasks to analyze the information and present it in a format that is easy to read and understand. A good technical writer needs strong writing and communication skills. They do not only convey information through text, and must be proficient with computers as well. They use a wide range of programs like Adobe Photoshop to create and edit images, diagramming programs like Microsoft Visio to create visual aids, and document processors like MadCap Flare to design and format documents.
