As a tool of strategic performance management and evaluating, the Balanced Scorecard emphasizes viewing an enterprise from four different angles of view including its finance, its customers, the internal business processes and learning & growth. The mutual driving relationship of the above four indexes have effectively guaranteed realization of organization's strategy. The Balanced Scorecard was born in the completely Western economic environment, so it's restricted in China to some extent. Step by step is the way to apply it properly. That is, to use it first at level of the entire organization or comprehensive strategy, then to apply it to the staff. The author's suggestion is to combine the marginal thought and the Balanced Scorecard to make marginal Balanced Scorecard. Trends of BSC's development will be personalization, individuation and composite. Its effective implementation also depends on sufficient communication.
