Technical writing and technical documentation are related but distinct concepts in the field of communication for technology-based products and services. Technical writing refers to the practice of creating clear, concise, and accurate written communication that explains complex technical information to a specific audience. Technical writers are responsible for creating a wide range of documents such as user manuals, installation guides, online help systems, and technical reports.
On the other hand, technical documentation specifically refers to written materials that provide detailed instructions and explanations on how to use, operate, maintain, and troubleshoot technology-based products and services. Technical documentation is usually created for end-users, but it may also be used by technical support staff, developers, and other stakeholders. Documentation specialists are responsible for creating and maintaining technical documentation, and they typically have a background in technical writing, as well as experience in the field in which they are documenting.
In summary, technical writing is a broader term that encompasses a variety of written communication that explains technical information to a specific audience, while technical documentation specifically refers to written materials that provide instructions and explanations on how to use technology-based products and services.
