Excellent post on selling to large organizations. This quote jumped out at me because it explains the value of good salespeople. However, the whole article is a great read.
"Often these processes are so complex that almost nobody inside the company knows how they work. Excellent enterprise sales reps will guide a company through their own purchasing processes. Without an enterprise sales rep, many companies literally do not know how to buy new technology products. A top notch enterprise sales person not only knows her customer's process better than the customer, but will be skilled at characterizing the value of her product to each decision maker independently. This will involve product demonstrations, proof of concepts, complete return on investment analysis and even competitive positioning. The sales rep will work with the various constituents to help characterize the value proposition their management teams."
