The instructions should name what matters most when everything cannot be done at once.

Instructions written as a flat list assume unlimited time, which nobody has. When the day goes wrong and only half the list is possible, the person doing the work has to guess at priority, and they will guess using what they can see rather than what you know. Then you find out later that the important thing was the one that got dropped.

Whenever you hand over a set of tasks, mark which two matter most and say what to do if there is not time for the rest. It takes one extra line and it removes the worst part of someone else’s bad day.
