I am studying marketing and we touch this topic but the teacher did not come to major depth, I already saw the Internet information but I do not have the completely clear idea have certain doubts. Also I would like knowing about a company that it will apply benchmarking in his sale process shortening steps not to lose very much the time in the delivery of the product.
Thanks to that they could help me.

Later I will be trying to reach port with some sand granite.
