About the Demand Driven Institute

The Demand Driven Institute (DDI) is dedicated to proliferating consistent demand driven methods approaches through education, training and certification. The Demand Driven Institute has a global presence through its partnership with the International Supply Chain Education Alliance (ISCEA) and its global network of affiliates. DDI’s Certified Demand Driven Planner (CDDP) Program is quickly becoming the world standard for the emerging demand driven methodology in planning, scheduling and execution. The Demand Driven Institute (DDI) was founded in 2011 by Carol Ptak and Chad Smith, co-authors of Orlicky’s Material Requirements Planning, Third Revised Edition.
