A crew is a body or a group of people who work at a common activity, generally in a structured or hierarchical organization.
A location in which a crew works is called a crewyard or a workyard.
[1] The word has nautical resonances: the tasks involved in operating a ship, particularly a sailing ship, providing numerous specialities within a ship's crew, often organised with a chain of command.
Traditional nautical usage strongly distinguishes officers from crew, though the two groups combined form the ship's company.
Members of a crew are often referred to by the titles crewmate, crewman or crew-member.
