Technical communication is a broad field and includes any form of communication that exhibits one or more of the following characteristics:
Communicating about technical or specialized topics, such as computer applications, medical procedures, or environmental regulations.
Communicating by using technology, such as web pages, help files, or social media sites.
Providing instructions about how to do something, regardless of how technical the task is or even if technology is used to create or distribute that communication.
The value that technical communicators deliver is twofold: They make information more useable and accessible to those who need that information, and in doing so, they advance the goals of the companies or organizations that employ them.
