Which concept focuses on information sharing and collaborative planning to reduce forecast errors in supply chains?

• A. CPFR: Collaborative Planning, Forecasting, and Replenishment.
• B. JIT: Just-in-Time.
• C. TOC: Theory of Constraints.
• D. VMI: Vendor Managed Inventory.

Answer: (A)

The idea being tested is about sharing information and coordinating plans across trading partners to improve forecast accuracy. CPFR stands for Collaborative Planning, Forecasting, and Replenishment, and it creates a process where retailers and suppliers openly share sales data, forecasts, promotional plans, and inventory information to develop a common forecast and replenishment plan. This collaboration helps correct forecast biases, smooth demand signals, and reduce the bullwhip effect, leading to more accurate forecasts and better timing of replenishments.

Other approaches focus on different goals. Just-in-Time aims to minimize inventory and waste with tight production and delivery timing but doesn’t inherently require cross‑company forecast collaboration. The Theory of Constraints targets bottlenecks to maximize throughput rather than aligning forecasts across partners. Vendor Managed Inventory shifts responsibility for stocking to the supplier, but the core emphasis is not the joint forecasting and planning process that CPFR formalizes.
