 Most users do not become expert users on their own. After some time, users will become stagnant with their efficiency with a system. They will keep using methods that might be inefficient but still familiar/satisfying to use. This can reduce productivity, so designers should try and implement ways to inform the user of more efficient methods. These designs should inform users in a non-obtrusive manner (not long tutorials).
