Mass Production (Civ6)

Mass Production is a Renaissance Era technology in Civilization VI. It can be hurried by building a Lumber Mill. 
In Civilization VI: Gathering Storm, it requires Military Tactics, Buttress and Education.

The concept of mass production, where different items are made exactly the same using uniform parts which can be interchanged, prepares humankind for the Industrial Revolution, which will change the world as we know it. The full scope of implementation of this concept has to wait until such time as technology develops, but in the Renaissance some things can already be mass-produced. The invention of the printing press allows mass production of standardized texts, and the utilization of uniform planks allows mass production of ships. A new structure is invented to implement this in Harbor districts: the Shipyard.
This tech is usually not very useful to any non-seafaring civilization. In fact, even civs with coastal cities but no great navies can't benefit that much from it: the tech only enables the Tier II Harbor building, whose utility is highly dependent upon the Harbor's adjacency bonus, and adds little else to the city but . The Venetian Arsenal is a useful wonder, albeit somewhat difficult to place.
Now seafaring civs have much more use for the Shipyard - besides the bonus (which is likely to be bigger in the cities of civs specialized in coastal settling), it adds the usual other bonuses, of which the XP bonus is maybe the most important to further boost your growing navy.
But regardless of what use the Shipyard is, this tech also unlocks the all-important Industrialization in the next era. For this reason only, every civ will need it sooner or later.
