What is DDMRP?

Demand Driven Material Requirements Planning is a formal multi-echelon planning and execution method to protect and promote the flow of relevant information through the establishment and management of strategically placed decoupling point stock buffers. DDMRP combines some of the still relevant aspects of Material Requirements Planning (MRP) and Distribution Requirements Planning (DRP) with the pull and visibility emphases found in Lean and the Theory of Constraints and the variability reduction emphasis of Six Sigma. These elements are successfully blended through key points of innovation in the DDMRP method.


Demand Driven Material Requirements Planning has five sequential components. This figure illustrates these components, their sequence and how they relate to the mantra, “position, protect and pull.” The first three components essentially define the initial and evolving configuration of a demand driven material requirements planning model. The final two elements define the day-to-day operation of the method. DDMRP is most common the start of an organization's transformation to a Demand Driven Adaptive Enterprise.

Evaluate the results that you would obtain in terms of service level and inventory turnover operating your supply chain under Demand Driven MRP to know the benefits of this alternative.

  • Get a perspective of how DDMRP buffers support various demand patterns over time
  • Enable ‘what if’ analysis of the impact of various buffer parameters
    • Lead time
    • Minimum Order Quantity
    • Variability
    • Buffer Zone Adjustments
    • Planned Adjustment Factor

Analysis of multi – level environments

  • Various end products pulling against shared intermediate and purchased parts
  • Distribution networks with forward locations, DCs and central buffer

Replenishment + ® is an inventory and materials management software designed to enable a pull system based on real demand, using the Demand Driven MRP methodology. This is the first software in the world fully compatible with DDMRP.

Companies that implement Replenishment + ® see huge leaps in return on invested capital (ROI) through 4 aspects:

  • Increased service levels
  • Increased sales
  • Total reduction of inventories
  • Cost reductions associated with supply chain management

The Demand Driven Planner (DDP)™ Program is designed for planning, purchasing and supply chain personnel responsible for implementing and maintaining a DDMRP implementation.  Designed by the leading authorities on DDMRP at the Demand Driven Institute, the Demand Driven Planner program is comprised of 13 modules of in-depth DDMRP education. The DDP Program is THE official preparatory course for the Demand Driven Planner Professional (DDPP)™ certification exam.

Note: Each participant of the DDP will receive a certificate of completion from the Demand Driven Institute.
