A good introductory blog post for beginners:
What is Technical Writing?
Technical writing unsurprisingly enough, refers to writing that is technical. Although this may seem like a fallacious definition, it’s an important one to remember. Too many technical authors make the mistake of creating documentation that is either too technical, or too ‘literary’. A good technical author should be able to adjust the balance between the two to suit the end user of the documentation.
Technical writing is a lot like fresh air, pervasive and yet pretty much invisible. In the weird wired world in which we find ourselves, technical writing is everywhere.
Software manuals, user guides for home appliances, instructional leaflets, emails, letters, reports, technical news reports, statistics and biographies on television sports shows all are examples of technical writing to which people are exposed to on a daily basis. If you have ever tried to program the time settings on a home video recorder and flung the manual across the room in disgust, you threw a piece of technical writing (although obviously not a very good one!).
