Abstract
The essays and arguments on management strategy up to the time seem to mainly concern an individual firm and the domestic market, although that is not explicitly stated. But now, it is needless to say that almost of firms organize a group with several tens to hundreds of consolidated subsidiaries and tie-up firms to compete with others in the global market. Namely, it could be said that the strategy of the group of firms but not the firm itself is requested against the global market. Moreover, the speedy implementation is requested for the strategy and the group reorganization by M&A is requested to be an every day affair. Accordingly, the structure of management is changing from head office controlling to autonomous distributed controlling by regions. Therefore, the structure of global strategy is discussed with the managerial structure.
