How early staff work gave the Royal Navy organizational depth

What advantage came from training Royal Navy personnel from a young age?

It created organizational depth by giving midshipmen and junior officers practical staff experience long before senior command.

The Royal Navy exposed officers to staff work while they were still midshipmen. Flagships could use young officers, spare lieutenants, and personnel from ships in dock for planning tasks without counting all of them on the permanent staff establishment. This created a reserve of people who understood administrative and operational work before reaching senior rank. A distant admiral could keep a lean formal staff and expand it with officers who would otherwise be temporarily underemployed.
