The market of national freeway bus service has become more and more competitive. In the completive market, these bus service carriers must think over their own strategy, and use the performance measurement system linking to strategy to guide the behavior of the employee. In 1990s, Kaplan and Norton addressed the “balanced scorecard”, a new performance measurement system that fit future organization, in view of defects of the traditional performance measurement system. That just fits the needs of these bus service carries. We took a bus company as a case study, and designed a balanced scorecard for it. Because this company had the ambiguous strategy, we constructed “an adjusted balanced scorecard analytic framwork”. After empirical testing, we found applying balanced scorecard can provide a performance measurement system to monitor the performance to their strategy from four perspectives. And by using the new analytic framework, the company can get significant management implications.
