In the workplace, a slot is a specific block of work whose completion supports the achievement of a key objective. Prioritizing deadlines and tasks using slot-based schedules can improve team productivity and increase the likelihood of meeting important milestones on time. For example, setting timelines for the completion of projects can support teams by ensuring that urgent tasks are given priority over those that can wait until later in the day.
