Mise en Place

Etymology

French for “putting in place,” from "mettre" (to put) and "place" (position). It began as professional kitchen shorthand for the prep a cook lays out before service, and has since escaped the kitchen to describe organized readiness in general.

What it names

Example
Because her mise en place was done, she could sear, deglaze, and plate the dish in ten unhurried minutes.
Related idea
A physical cousin of deep work: both depend on removing friction and interruption in advance so that attention can flow uninterrupted during the actual task.
