Technical writing is sometimes defined as simplifying the complex. Inherent in such a concise and deceptively simple definition is a whole range of skills and characteristics that address nearly every field of human endeavor at some level. A significant subset of the broader field of technical communication, technical writing involves communicating complex information to those who need it to accomplish some task or goal. Good technical writing results in relevant, useful and accurate information geared to specifically targeted audiences in order to enable a set of actions on the part of the audience in pursuit of a defined goal. The goal may be using a software application, operating industrial equipment, preventing accidents, safely consuming a packaged food, assessing a medical condition, complying with a law, coaching a sports team, or any of an infinite range of possible activities. If the activity requires expertise or skill to perform, then technical writing is a necessary component.
