11 The Balanced Scorecard Measures that Drive Performance Harvard Business Review Kaplan, RS and Norton DP Feb 1992

12 The Balanced Scorecard Translating Strategy into Action Harvard Business School Press Kaplan, RS and Norton DP Feb 1996

13 Definition The Balanced Scorecard is a framework that translates vision, mission, strategic intent, legislation, external impacts and long-term business direction into performance drivers. 1

14 Application of the Balanced Scorecard to WDM Problem The Balanced Scorecard is an ideal tool for developing a WDM Strategy incorporating a wide range of activities bridging many aspects of a water supply business. 14
