We Help You Hire, Promote and Develop Exceptional Leaders

Our Approach

We failed to create a 25th hour in the day. Instead, we created Leadership 480SM.

based on our work with millions of leaders for five decades, we came to one simple conclusion: time is the #1 barrier to great leadership. 

We can change that. Leadership 480SM is DDI’s strategic framework to help you hire, promote, and develop exceptional leaders who maximize their effectiveness in every minute, every day, and every month of their careers. And it all revolves around one powerful number: 480.
