Key Points

  • Theory Z is a work of William Ouchi’s observations about Japanese corporate culture and management compare to American management style.
  • 7 characteristics of Japanese management in Theory Z of Ouchi are include: lifetime employment, evaluation, slow promotion, non-specialized career path, implicit control mechanism, collective decision making, and holistic concern.

Lifetime Employment

Lifetime employment makes employees feel connected to the organization and become a part of the organization.

If you ever heard some of Japanese corporate culture. You may know Japanese employees will not leave their office immediately, but they will keep working until their work is finished, because they think it is responsibility (not duty).

Evaluation

Evaluation of the Japanese management will evaluate the work as a team.

This is a different way of western culture at all. Unless some of western culture may work as team, but most of western management always evaluate as individually.

Slow Promotion

Promotion in Japanese company happen slowly. Sometimes it takes more than 5 or 10 years to get promoted, because seniority is involved to promotion.

This is the reason why many Japanese managers are always older than western managers.

Non-specialized Career Path

In many Japanese organization had quite none-specialized career path.

Many times employees have to move into other department to learn about different task. Yes, you can be promoted into different task.

Implicit Control Mechanism

Many protocol rarely written in a clear rules. Mostly use culture to involve work and control.

For example, Japanese employees continue working after the time off. That is not defined in the company’s rules at all (In some companies, it doesn’t pay extra money). But many people do that because they think it is their responsibility to get their job done.

Leader is always hands-off from how employees finish the job. Employees can do anything to make their job done.

Collective Decision Making

Japanese always use group decisions, everything must go through the group’s comments and vote.

Although, an idea is very good, but the group say no for that idea, it will never happen at all.

Holistic Concern

Japanese corporate culture is family-like as we mention above. The emphasis is on interdependence rather than on individualism.

For example, they concern for the health and happiness of colleague, not just concern about works.
