It's a lot easier to teach many people how to receive communication in one style than it is to teach everyone to send communication in many styles. We can, and many organizations do, write style guides for internal communication. The most successful such style guides (eg. military, intelligence) emphasize the ABCs (accuracy, brevity, clarity) any to avoid extraneous verbiage.
If your coworkers respond negatively to a simple, direct question like "Why didn't you do it this way?", they can be trained to handle professional communication more dispassionately (more professionally).
There’s a whole division dedicated to undoing military communication style to adapt it to the real world in the private sector. Just FYI. Also, the word “didn’t” doesn’t exist in that communication style… “unable”, “status red”, “negative”, “not able”. The words “can’t” and “didn’t” are stricken.
