On page 139 of EntreLeadership by Dave Ramsey he writes about using the DISC during hiring,
"This tool gives us a quick look at the personality style of the person. We want to see if their style fits with the job, how their style will fit with the team they will join and how they will interact with the style of their immediate leader. This is a quick test of twenty-something questions that just takes a few minutes, but it reveals with fairly good accuracy a person's tendencies."
He also writes,
"A great indicator (of success) is relational intelligence. The ability to get along with others and work with others to achieve shared goals is huge as an indicatory of winning."
