prioritise

To prioritise is to decide what must be dealt with first. Prioritise the work, prioritise safety, learn to prioritise.

It means ranking rather than simply working hard, and the whole point is that some things get pushed down the list — a plan where everything is a priority is not a plan. It is heavily used in management writing, sometimes as a way of avoiding saying what will not be done. Note prioritisation; and that this is the British -ise spelling, with prioritize standard in America and also acceptable in Britain.
