DDMRP (Demand-Driven MRP) is a "pull flow" planning method that places buffer stocks in the right places in the chain, decouples uncertainties, and prioritises execution by exceptions.

Result: fewer chain reactions, calmer decisions, a customer service that delivers.

What is DDMRP?

Demand-Driven Requirements Planning is an innovative 'pull flow' methodology at multiple levels that allows planning of stocks and materials.

This methodology enables a company to align more closely with market demands and to prioritize execution and planning more quickly and calmly.

DDMRP was introduced to the world through the book "Orlicky's Material Requirements Planning", third edition revised by Carol Ptak and Chad Smith.

Le MRP au 21ème siècle

The MRP, initially developed in a limited mode in the 1950s and 1960s, only really took off in the 1970s, when computer systems made its widespread adoption possible and APICS launched its "MRP crusade" to make it more popular.

MRP evolved in the late 1970s and 1980s to become MRP II and eventually ERP. But the core of today's ERP systems, at least in the manufacturing sector, is still the MRP processing logic, which has remained practically unchanged since the 1970s.

The 5 levers of DDMRP

  • Strategic positioning of stocks

    We place buffers where they best protect the flow.

  • Profiles & buffer levels

    Each family of items has green/yellow/red areas adapted to its variability.

  • Dynamic adjustments

    The levels adjust with the season, promotions, and trends.

  • Demand-driven planning

    We trigger orders when necessary, where necessary, according to the net flow.

  • Visible & collaborative execution

    We prioritise by exceptions (red/yellow), align the roles, and document the decisions.
