Why did Selzer want to observe how an engineer writes?
Selzer felt that courses that taught the different writing styles and how to perform them had skipped over the technical writing field. He felt that the people who wrote technically for their jobs didn't have a standard form, and made up their own style. He wanted to find the strengths and weaknesses in that style.

Which of Selzer's findings intrigued you?
Selzer found that Kenneth, the engineer, did very little revising. He would spend a lot of time working on a layout for his proposal, report, or other writing, then would work very quickly, and with a purpose, to create the document. When the first draft was created, he would have his secretary type it up, and then he would read through it and make a few minor adjustments and be done.

How did Selzer convince you to believe in his findings?
Selzer looked over all of the notes, writings and references and analyzed them, along with a couple of face-to-face interviews.
