I found these chapters interesting and useful for my professional writing technique. Chapter four brought up some points that were helpful like trying to identify the information your reader needs. Instead of presenting the information you find most important tailor your documents to what your readers really needs to be reading about. I also liked the idea of putting your bottom line first. This way your reader will know your main point without having to fish for it or stop reading.
Chapter 5 also had interesting points I thought were helpful. The point about not only using sound reasoning but also convincing your readers that your reasoning is sound. This goes back to the ethos rhetoric. To persuade your readers you must be logical and also make them see that you know what you are talking about and that they should respond to your writing.
Chapter 16: developing shared understanding of the communication’s objectives. You must learn about your reader’s values and needs. If you find out what they want you can appeal to it and become a stronger persuasive writer. The idea about making and sharing plans is very important because if your group members are not all on the same page it can be difficult to achieve your goals.
Chapter 23: writing descriptive and understandable instructions can be complicated because what you find understandable may not seem that way to everyone that will be reading the instructions. Being organized and through is the best way to go.
