From Pegasus: Think about the last time you undertook a change initiative, whether in your work or personal life. How did you measure progress toward your goal? How did you know when to make adjustments? The answer in most cases is through feedback. When a company launches a new product, they monitor sales data and customer comments; this information, in turn, influences their marketing efforts and guides them in tweaking the product to better meet people’s needs. Without data about the results of our efforts, it’s impossible to evaluate performance, fine-tune improvement efforts, and gauge the success of different actions.
