NASA SP7010, aka Clarity in Technical Reporting by Dr. Samuel Katzoff, manages to say more about technical writing in 30 pages than most books ten times the size. There’s not a single illustration or bullet point, yet it’s lucid and precise.
It seems that Dr Katzoff took special care to ensure that young engineers at NASA knew how to communicate. As chief scientist at the NASA Langley Research Center, he certainly knew the importance of good technical reporting.
NB: I had assumed that Dr Katzoff, from various sources on the internet, had passed on. I’m told (see below) he’s alive and well. If he didn’t say something in Clarity in Technical Reporting about checking sources, well …
Best wishes to Dr K., anyway!
