The Mass Transit Railway Corporation Ltd (MTR) of Hong Kong implemented a total management system (TMS) in its operations engineering department in 1998. In view of the many benefits brought about by TMS upon its implementation, the system has extended to cover the railway operations since 1999. Comparing performance before and after the implementation of TMS, almost all balanced scorecard indicators have shown improvement well beyond the target levels. This paper highlights the performance differences before and after the implementation of the TMS.
