Definition of Technical Writing

Our textbook gives this definition:

Technical writing writing done in the workplace; the subject is usually technical, written carefully for a specific audience; the organization is predictable and apparent; the style is concise; the tone is objective and businesslike; special features include visual elements

This is a very broad definition and covers a lot of different types of writing, from emails, to reports, to instruction manuals. However, we will go in detail now through some common characteristics that distinguish it.

Characteristics of Technical Writing

Subject

  • Technical writing has a technical or factual subject.
  • It is expository writing—it explains a subject to the reader or informs the reader about the subject, and also fulfills the special needs of a specific reader.
  • In technical writing, the need is often to share information or have someone perform an action.

Audience

  • The audience is carefully considered, targeted, identified, and analyzed.
  • The audience is never just “anyone” or “everyone” in technical writing.
  • We need to know exactly who we are writing to, and why.

Purpose

  • The purpose is also very specific.
  • The technical writer expects the reader to take a specific action after reading, or to make a specific decision.
  • The reader depends on the writing to help them complete their task successfully.

Organization

อันนี้จะอยู่ใน Part Structure ของ Rubric

  • The organization is clear, predictable and apparent. Readers can find the important information very quickly.
  • Headings help readers quickly scan the entire document so they can choose which parts to read.
  • Readers often don’t need to read the entire document from start to finish. Technical documents are often scanned instead of read.

Style

  • The style is simple, concise, direct and straightforward.
  • Most sentences are short.
  • There are no surprises or confusion for the reader. The meaning is clear. It is not ambiguous.
  • Technical documents often use jargon, the specialized language of a technical field.

Tone

  • Technical documents have an objective, factual, businesslike and detached tone.
  • They are not subjective or emotional.
  • Technical documents are written to convey information, not to entertain or amuse.

Special Features

  • Use special features such as boldface, italics, CAPITAL letters, columns, underlining, and bulleted lists to draw readers’ attention
  • Also, the use of graphics such as tables, graphs, pictures, and diagrams helps the audience grasp complex information quickly.

Document Design

  • In technical writing, how the words look on the page is just as important as what the words say.
  • A cluttered document with poorly designed elements can confuse and overwhelm your reader.
  • Pages that are visually friendly help readers stay focused and find information quickly and easily.
