The objective of technical writing is to clearly convey some information to a select group of audience in a way that topic can straight away be understood.
Technical writing is a way of analyzing, generating and managing information about various products and technical procedures to be used in the generation of technical documentation.
Technical writers write and sometimes edit manuals, newsletters, user guides, online help files, reports etc. and many different types of text.
