151 Feedback Loop In traditional manufacturing since about 1920, quality control was a matter of inspection and testing at the end of the production line.The problem with this approach, as pointed out by W. Edwards Deming in the late 1940s, is that it didn’t identify the true causes of defects: all you would know is that there was a defect. Deming saw that variations can enter at every step in a production process and that the causes of variation need to be identified and fixed.With that approach, defects go down sharply and product quality can be improved almost indefinitely. Deming emphasized that all business processes should be part of a system with feedback loops. Managers should monitor the feedback data to determine the causes of variation, find the processes with sig- nificant problems, and then fix those processes.This single observation replaced procedures that had been in place for a couple of genera- tions and led to countless more innovations. Deming is one of the giants of management practice. Study his career and contributions to understanding the behavior of costs and you will be a far more effective manager.

The value of these metrics lies in their ability to give a factu- al basis for decision-making. Strategic feedback comes from the spread across four perspectives. Diagnostic feedback for individual processes is also available. The feedback from the measurement methods themselves helps indicate which provide useful data. That the vision has been expressed through data also means that quantitative inputs are available for various forecasting and modeling decision support systems. All this can be said to result in management by fact. Some critics maintain that BSC and similar inclusive manage- ment systems are nothing more than what good businesses do regularly and you shouldn’t have to go through all the froufrou. In one sense they are correct. Successful organizations often come to such practices through trial and error. BSC just lays out the all the dance steps on the floor for you to follow.
