When you're assigned a new company
You need this when: you first start working an account.
What it gives you: a map of who is most likely to be impacted by the buy, sorted by who feels the problem and who controls the decision, plus a score that helps you prioritize.
Without it: you're doing a volume play, and while numbers help, 200 calls to people who don't feel the pain or can't impact the decision isn't going to move things forward.
