This session is intended for Odoo end users and customers, especially those in the manufacturing sector, and the app presented is based on Odoo Enterprise version 12. Demand Driven Material Requirements Planning is an innovative methodology for planning and inventory management that incorporates concepts from Lean, ToC, Six Sigma and MRP. This allows organizations to align their production and their supply to the market demand, enabling better and faster decision making, both at operational and strategic levels. In an increasingly variable and volatile environment, all organizations in a supply chain are affected by the "bullwhip effect". Unpredictable demand signals, increasing SKUs, shorter customer tolerance, longer Lead Times, and lots of customizations... these are only a few of the factors that describe the reality of the 21st century; DDMRP rises up as an answer to this complex scenario. This talk will allow you to understand the basic concepts of this methodology and how they are applied in Odoo.
