Craig Douglas’ post here is meant primarily for LE. Don’t take this as me trying to be the guy telling LEOs how to do their job. I’m simply passing information along from SME and noted instructor, Craig Douglass of Shivworks. Douglas’ main point here is to be precise in your instructions. He also suggests emphasizing what you don’t want your subject to do. Having said all this, I find Douglas’ points to be applicable outside of LE as well.
I work in IT in the finance industry as my primary job and I also do contract work in other fields. When interacting with people, I find that precise language makes all the difference in the world in helping me help them solve their problem. Precise wording of the description of a problem makes diagnosing that problem and finding the solution faster and simpler.
