Certified Demand Driven Planner (CDDP)

About the CDDP Program

The Certified Demand Driven Planner Program was created by a global partnership between the International Supply Chain Education Alliance (ISCEA) and the Demand Driven Institute (DDI). Internationally accredited by the IISB, the purpose of the CDDP Program is to educate operations and supply chain personnel on the methods and applications of Demand Driven Material Requirements Planning (DDMRP).

DDMRP is a formal planning and execution method designed to correct the inadequacies and inappropriate rules of conventional Material Requirements Planning (MRP) given today’s more volatile, complex and service oriented supply and manufacturing scenarios.  The method was first fully articulated in the latest edition of Orlicky’s Material Requirements Planning (McGraw-Hill, 2011) that was co-authored by Carol Ptak and Chad Smith.
