Wikipedia: Working title
A working title, sometimes called a production title or a tentative title, is the temporary title of a product or project used during its development, usually used in filmmaking, television production, novel, video game development, or music album.
 
Purpose
Working titles are used primarily for two reasons – the first being that an official title has not yet been decided upon, with the working title being used purely for identification purposes, and the second being a ruse to intentionally disguise the real nature of a project.
