Practice shows that combinations of surveys, such as an employee satisfaction with a customer satisfaction survey, provide synergy effects for your organization. Employees who are balanced, well situated and offered future perspective, perform better. Customers who are properly assisted or whose expectations are even exceeded, will definitely come back. If both employees and customers notice that their opinion is valued, it will create a win-win situation. Within your organization you will have more commitment and externally it will lead to customer loyalty. This has a mutually reinforcing effect.
