One of the greatest benefits of the internet is its ability to automate almost everything, surveys being one of them. Many companies offer some kind of end-user experience survey for their customers upon the conclusion or cancellation of a service. This allows them to simply glean information about customer pain and experience without having to go out and search for them.
This means that a businesses can design their product around the experience of previous customers, and adapt their methods to better meet and heal their pain. And it all comes from a simple survey!
This creates a new question that many salesman try to solve; how can salesmen create a way for their potential buyers to come to them, instead of them having to go to their buyers? Until the actual process of prospecting from potential customers can be automated, salesmen will have to resort to the old fashioned way of sales.
