I am honestly not sure how to improve matters at this point. I tried to lead by example to little avail. E.g. "look at how I documented that kind of issue here as a guideline moving forward". We tried issue templates that are effectively a checklist of required information, but not every problem fits into a round hole. Many (most?) are actually quite odd-shaped once you apply nuance and context.
There are also those really annoying interactions in Teams where someone will type out "you have a minute?" instead of just describing what they need someone's attention for up front.
At some levels, I wonder if I might have the wrong team for this kind of job. How does HN deal with team members who have trouble slowing down and communicating their thoughts well?
