How do you identify the true decision-maker in a complex corporate hierarchy?

While pitching a big client, you need to make sure that you are targeting the high ranking authority there. You don't need to be focusing on the people that will not have much impact when it comes to decisions. There should be a way of you getting the contact of those that have their decisions binding on the company. Doing this will save your time and even all your efforts in getting such tasks.
