In contrast, the United States management style is best described as‘ mostly characterized by supervisory style stressing more on theory X, task oriented and transactional leadership methods. US managers are more interested in results than processes and they tend to be less participative than Japanese managers with respect to decision making. US managers follow a top-down approach for decision making where the top management makes a decision and delegates it to the subordinates. Also US management works on the idea that employees are semi variable assets and can be hired and fired as required.
Therefore, this was just a comparison between the Japanese and US management styles and none of these may be termed as‘ best’, because a management styles varies from country to country and organization to organization.
