Unknown unknowns are completely unforeseeable risks that cannot be identified in advance; the scenario describes risks based on known historical patterns, making them known unknowns.

Known unknowns are risks that the team knows could occur but cannot predict precisely - such as delays that 'always happen' or the need for additional equipment 'usually needed beyond forecast.' These are handled by adding contingency reserves to the schedule and budget, which is exactly what the team is doing. Because these risks are identifiable and historical patterns exist for them, they can be planned for, distinguishing them from unknown unknowns.

Risk management is the broader process discipline, not the specific classification of these reserve items.

Management reserve is used for unknown unknowns, not for predictable, recurring items the team has already anticipated.
