A daily prioritization check-in involves asking questions about each task planned for the day to determine what is most important to focus on first. The questions help establish if a task truly needs to be done now, if it is the most important compared to other tasks, if someone is waiting on the task's completion, and if not working on it could have unknown consequences. If the answers determine another task is more urgent, the planned task is lowered in priority or saved for later in the day.
