Good technical writing makes its points first and then goes on to justify them. Drama writing is fine for murder mysteries, but you should never hold a technical reader in suspense.
Tech writing has to convey technical information. Good technical writing should do this with as few words and pictures and in the shortest time possible.
I like to collect the expressions for damage claims that civil lawyers use in their lawsuits. If you are writing an angry letter to a company or person, be sure to sprinkle a few of these terms in the text.
Good technical writing is short, tight, and to-the-point. It is called inverse pyramid since the important part is on the top. You should avoid drama style or storytelling in tech writing.
