I do not personally live by those three categories but I have found use for making triggers for when action needs to happen based on observable need for them,

The confusing thing is when the same action results in benefit occasionally and in drawback occasionally. When you group the occasions into a benefit group and a drawback group you can occasionally see a feature in common in one that isn't present on the other. That is a good reason to focus on that feature out of the possible multitudes of features situations have.

When there are multiple competing principles that give contradictory advice their assumptions might not all be fulfilled to the same extent. A might be good and B might be good but are A and B always good at the same time?
