About the Demand Driven Planner (DDP) Program

In this programm you will learn the principles of Demand Driven Material Requirements Planning (DDMRP) and how these principles are applied to provide a sustainable competitive advantage in supply chain management.

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.
It enables superior operational performance: higher service levels and shorter lead times, while overall inventory levels and supply chain cost are minmimized, all driving better operational and financial performance.

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.

The DDP and an introduction of DDMRP is the ideal starting point for creating a demand driven enterprise as it explains how to build the core of the Demand Driven Operating Model.

The program can only be taught by instructors who are endorsed by the Demand Driven Institute, ensuring quality instruction and continuos updating of the content.

Only with Catena Strategies: All our DDP courses are taught by Christoph Lenhartz, Master Instructor of the Demand Driven Institute!



Two days of intensive learning through lectures, exercises and class discussion will provide you with the following understanding, knowledge and skills:

  • Understand why planning as it is done today just doesn't work and how to fix it without reengineering the entire company.
  • Know how to deal with an unpredictable market where demand is dynamic and creating a planning and execution environment that manufacturing can successfully follow while lowering your internal costs.
  • Create a lead time and service level advantage over your competitors by understanding the key elements of reducing lead time.
  • Leverage inventory in ways not understood prior which go beyond just simply placing stocks everywhere, turn inventory into a strategic tool.
  • Improve conventional Sales and Operations Planning to allow true alignment between customer demand and operations capabilities and resources.
  • Learn about how those firms that are a pioneer in DDMRP are just simply better than their competitors in supply chain performance.
  • Be able to design the core of a Demand Driven Oerating Model for your company.


CDDP included in 2015 Gartner Market Guide for Supply Chain Certification Programs

Gartner, the Supply Chain reserach company, has included the Certified Demand Driven Planner (CDDP) Program in its Market Guide for Supply Chain Certification Programs. It is one of ten programs in the guide. Gartner clients can access the report here.

Certify your knowledge and become a Demand Driven Planner Professional (DDPP)

The DDP program is the official preparation course for DDI's DDPP exam. Upon successful completion of that exam participants receive a DDPP certificate and may place "DDPP" in their professional title. The 50 question exam is completed online through DDI's online testing system after course completion. You can schedule a testing session that meets your personal schedule. Please contact us by email at This email address is being protected from spambots.

Who should attend?

The DDP training provides knowledge and capabilities to understand and apply DDMRP concepts in supply chain management from procurement to production and operations, inventory management, logistics, distribution, wholesale and retail.
It is especially suitable for supply chain professionals:

  • Supply chain, operations and demand planners and schedulers
  • Managers for production, supply chain, logistics, operations
  • DDMRP implementers
  • Sales and operations planning professionals
  • SCM consultants
  • IT architects in SCM

Taking full advantage of the DDMRP methodology throughout the organization requires full support from management including finance and sales. Therefore we highly recommend that senior managers attend this training or one of our other Demand Driven training options. Experience (since 2012) shows that early management involvement is a key driver for successful implementations of  DDMRP.
