Using scarce, better accomodations as carrot to induce improved performance from sailors

The navy quickly decided that the sailors who perform better should get the roomier accommodations ashore. This led to remarkable increases in performance by junior, unmarried, sailors seeking more comfort during the 60-80 percent of the time their ship is not at sea. There are numerous skills, and tests to measure them, that sailors can, or must, take. The draw of more comfortable living quarters has motivated sailors to an extraordinary degree, to learn more, take more tests, and do better on the job. This happened to such a degree that some NCOs think it would be a good idea if there were never enough barracks rooms for all the junior sailors.
