Beyond clear writing, there
are a number of special techniques that technical writers employ - here are just three of the basic techniques:
1. The technique of boiling down complex information to a simpler, more readable form.
2. The technique of transforming diverse information into something coherent and meaningful.
3. The technique of arranging information in a way that makes it easy to find.
I should add that these techniques usually involve more than just writing - they also involve some desktop publishing as well.
