Crowd sourcing is most likely your better method to evaluate a product or service because it helps the employee and or customer make sure the product functions properly. For example if you go to best buy and purchase a laptop or desktop computer crowd sourcing does come into play and a customer has the right to even test the product to make sure it works. Good luck!
