This question is not so easy to answer. Of course, we carry out customer satisfaction surveys, but even then, it is not so easy to filter out the everyday humdrum from the answers. We test internally and at customers and other stakeholders what they think of our increasingly customer-oriented approach. We test that our strategy is implemented and is also reflected in our market approach. All very nice, but still it smells like allowing the fox to guard the chickens.
Of course, there never is only one way to test the approach, but what I consider near to the ultimate test, is that the customer wants to identify with us. How much more authenticity can you achieve? And how do you get there? What I thought a good idea was to present customer testimonials not only as typed internet message but recorded in images to emphasise the authenticity. If the customer is so open about giving his or her opinion about us and identifying with us, it must be an authentic experience.
