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) co-authored by Carol Ptak and Chad Smith.  Chad Smith serves as the CDDP Program Director.

The CDDP Program is comprised of 10 modules delivered in 16 CONTACT hours over a 2.5-3 day time range.  Testing is then completed through the ISCEA's iProctor system after course completion and through scheduled testing sessions. Upon successful completion of the exam participants receive a CDDP certificate and may place "CDDP" in their professional title.

CDDP Exam Preparation Information

Each Certified Demand Driven Planner Examination is comprised of 125 multiple choice questions chosen from a larger question pool.  Each exam provided is unique in the questions and sequence of the questions.  A passing score requires 70% correct answers. 

The exam is delivered online through ISCEA’s iProctor system.  You must have a computer with good internet connectivity and a webcam to take the online exam. 

Exam schedules are posted at: http://cddp-online.eventbrite.com/#.  A special code will be furnished to each student that will negate the fee for two attempts at the exam.  The course fee includes two attempts at the test. Additional attempts are $250 per attempt.

The examination questions are broken down into 7 categories.  Below is a description of those categories.

The first category is about the problem that DDMRP is solving.  Included in this category are known issues with conventional MRP and the impact of variability on manufacturing and supply chains.
Study Resources:

  • Chapters 1-4 of Orlicky’s Material Requirements Planning 3/E
  • Various DDMRP white papers
  • Chapter 1 of Demand Driven Performance – Using Smart Metrics.

The second category is about the basics of DDMRP.  This category includes the fundamental principles that DDMRP is founded on, it’s typical effects in manufacturing and supply chain environments and key differences it introduces to planning and execution.
Study Resources:

  • Chapters 4 and 22 of Orlicky’s Material Requirements Planning
  • Various DDMRP white papers

The third category is about Strategic Inventory Positioning.  This category includes knowing the fundamental factors behind determining decoupling points and the ramifications on the environments when decoupling points are placed. 
Study Resources:

  • Chapters 4 and 23 of Orlicky’s Material Requirements Planning 3/E
  • Chapter 3 of Demand Driven Performance – Using Smart Metrics

The fourth category is about Buffer Profiles, Level Setting and Zone Definitions.  This category includes what type of parts belongs in what type of buffer profiles, the buffer equations and average inventory position and ranges.  Study Resources:

  • Chapter 25 of Orlicky’s Material Requirements Planning 3/E
  • Appendix A of Demand Driven Performance – Using Smart Metrics

The sixth category is about the Planning aspects of DDMRP.  This category includes the available stock equation, order spike qualification, decoupled explosion and DDMRP impacts to the Master Production Schedule and S&OP Process.
