See TheoryXx, TheoryYy From http://www.stanford.edu/~krollag/org_site/encyclop/theory_xy.html : Human relation theorists emphasize the impact of individual characteristics like race, sex, class, cultural background on organizational and group behavior. Douglas Mc''''''Gregor's book on "The Human Side of Enterprise" [ISBN 0070450986] distiguished between Theory X (classical systems theory) and Theory Y (human relations theory). ---- The names are purportely meaningless, like LeftWing an RightWing in politics, so that they can be meant to be anything, as is convenient when future needs make the change necessary? ---- '''Relation to Extreme Programming''' ExtremeProgramming takes the TheoryYy approach. If you mistrust your people's commitment and motivation, you're certainly not going to trust them with a process like ExtremeProgramming. XP definitely assumes that its practitioners are dedicated professionals who really care about doing good work. Contributors: RobHarwood, MikeSmith ---- CategoryComparisons
