  • The Balanced Scorecard—Measures that Drive Performance

    CriticismPurposeCategoriesGoalsPerformanceCostManagersPhilosophyExampleEffectsDevelopmentSignificanceAdvantagesBenefitsWhat you measure is what you get. Senior executives understand that their organizations measurement system strongly affects the behavior of managers and employees. Executives also understand that traditional financial accounting measures like return-on-investment and earnings-per-share can give misleading signals for continuous improvement and innovationactivities todays competitive environment demands. The traditional financial performance measures worked well for the industrial era, but they are out of step with the skills and competencies companies are trying to master today. But given todays business environment, should senior managers even look at the business from a financial perspective? Should they pay attention to short-term financial measures like quarterly sales and operating income? Many have criticized financial measures because of their well-documented inadequacies, their backward-looking focus, and their inability to reflect contemporary value-creating actions. Shareholder value analysis (SVA), which forecasts future cash flows and discounts them back to a rough estimate of current value, is an attempt to make financial analysis more forward looking. But SVA still is based on cash flow rather than on the activities and processes that drive cash flow. Some critics go much further in their indictment of financial measures. They argue that the terms of competition have changed and that traditional financial measures do not improve customer satisfaction, quality, cycle time, and employee motivation. In their view, financial performance is the result of operational actions, and financial success should be the logical consequence of doing the fundamentals well. In other words, companies should stop navigating by financial measures. By making fundamental improvements in their operations, the financial numbers will take care of themselves, the argument goes. Assertions that financial measures are unnecessary are incorrect for at least two reasons. A well-designed financial control system can actually enhance rather than inhibit an organizations total quality management program. (See the insert, How One Company Used a Daily Financial Report to Improve Quality.) More important, however, the alleged linkage between improved operating performance and financial success is actually quite tenuous and uncertain. Let us demonstrate rather than argue this point.
