Technical writing is, at its heart, persuasion. If you, as the writer,
are not convinced that something of worth happened that needed reporting,
then your intended audience will probably be unconvinced as well.
What? You didn't think about who was in your audience before you
started writing? The written communication is a product. Products
need consumers, Think about the description of a customer-satisfying
product: inexpensive, accurate, easy to use, no squeeks, rattles,
or buzzes, works under a variety of conditions, self diagnostic,
etc. For a good written product these should read: concise, precise,
organized, consistent, complete, adequately referenced, etc.
Writing is the era of electronic media is emminently perfectable.
Learn from your mistakes. You wouldn't expect to make a complicated
product perfectly, or even adequately, the first time-would you? Continuous
improvement can only result from measurement of quality followed by
immediate corrective action. What is quality in writing? Quality is
usually more conspicuous in its absence. Few people can write poorly
enough to remove information from the brains of the reader. Instead
the poor writer often succeeds in taking up a lot of the readers time
without transmitting much information. Transmitted information per
unit time is a metric (units?) for determining quality. Another is
the "Fog Index" developed by Robert Gunning. The Fog Index
of 11 or 12 is near-optimal. Higher or lower values are undesirable.
