This involves identifying existing relationships that show a strong correlation between one measure and another with a standard value. A classic relationship is the correlation between job satisfaction and employee turnover. Suppose that in a project designed to improve job satisfaction a value is needed to reflect changes in the job satisfaction index. A predetermined relationship showing the correlation between increases in job satisfaction and reductions in turnover can directly link the two measures. Using standard data or external studies the cost of turnover can easily be determined as described earlier. Therefore a change in job satisfaction can be immediately converted to a monetary value or at least an approximate value. The conversion is not always exact because of the potential for error and other factors but the estimate is sufficient for converting the data to monetary values. Finding a correlation between a customer satisfaction measure and another measure that can easily be converted to a monetary value is sometimes possible. A strong correlation often exists between customer satisfaction and revenue. Connecting these two variables allows the monetary value of customer satisfaction to be estimated. In some situations a chain of relationships may establish a connection between two or more variables. A measure that may be difficult to convert to a monetary value is linked to other measures that in turn are linked to measures to which values can be assigned. Ultimately these measures are traced to a monetary value typically based on profits. Figure shows the model used by The model connects job attitudes collected directly from the employees to customer
