A ghost slot refers to a placeholder in a schedule or calendar that is left intentionally empty for flexibility or unforeseen circumstances. This term is commonly used in project management to allow for adjustments without disrupting the entire timeline. By incorporating ghost slots, teams can adapt to changing priorities or delays more effectively. It serves as a buffer to accommodate unexpected events or additional tasks that may arise during a project. Embracing ghost slots can enhance productivity and reduce stress by providing room for maneuvering in a structured manner.
