How to Analyze Different Personality Types in Sales

I use something that's analogous to disc, but I call my model deal. Deal stands for driver, expressive, amiable and logical. The driver personality is that task focused like to be in control individual. And then the amiable is a relationship driven individual who's not trying to control people or situations. They're really more thoughtful in terms of introspective and controlling themselves. So I use that as a four step model for people to try to make a quick analysis of who they're dealing with.
