William Ouchi came up with a perspective of organizational culture that premised on his observations of management practices in Japanese corporate and industrial culture. He labeled the Japanese model Theory Z. Theory Z describes a work environment that is characterized by trust, subtlety, and intimacy. Theory Z “suggests that involved workers are the key to increased productivity” (1981, p. 4). Trust, subtlety, and intimacy are central to such involvement. An atmosphere of distrust between workers and management inhibits productivity. He argues that a sense of trust must exist before people will make sacrifices that contribute to productivity.
