Demand-Driven Material Requirements Planning with Decoupling Point Buffers
Apply demand-driven material requirements planning by positioning strategic decoupling points, sizing red, yellow and green buffer zones, and generating replenishment orders from net flow position rather than unstable MRP signals.

About the programme
Course Overview
A small change in end-customer demand should not need to ripple back through every bill of materials level as an amplified, unstable order signal, yet that is exactly what conventional material requirements planning does when lead times stack up and forecasts shift. Demand-driven material requirements planning breaks that chain by positioning strategic decoupling points that absorb variability with a sized buffer instead of passing it upstream unchanged. This course works through selecting decoupling points using lead time, variability and customer tolerance time, then designing buffer profiles and sizing red, yellow and green zones so each buffer protects service without holding excess stock. Delegates calculate net flow position, generate replenishment orders from it, and prioritise open orders by buffer status rather than due date alone. The course closes with dynamic adjustment for known events, the metrics that show whether a buffer design is working, and a practical path for piloting demand-driven planning before a wider rollout.
Expected Learning Outcomes
Select strategic decoupling points using lead time, variability and customer tolerance time criteria.

Apply planned adjustment factors and recalculate buffers when usage or lead time genuinely changes.
Calculate net flow position and generate replenishment orders prioritised by buffer status rather than due date alone.
Monitor buffer performance and govern decoupling point and buffer sizing decisions as the network changes.

01Why Demand-Driven Planning and Where to Decouple
2 sessions · 8 points
Session 1Limits of Conventional MRP in Volatile Demand
- Explain how lead time and bill of materials explosion in conventional MRP amplify small demand changes into large order swings.
- Identify the demand and lead time variability signals that make a conventional MRP plan unstable.
- Distinguish dependent demand calculation from a demand-driven approach that reacts to actual consumption at each buffer.
- Recognise the planning nervousness and expediting cycle that strategically placed buffers are designed to remove.
Session 2Selecting Strategic Decoupling Points
- Apply the criteria used to select a decoupling point, including lead time, demand variability and customer tolerance time.
- Position decoupling points to protect a bottleneck or long-lead-time component from upstream variability.
- Separate items and locations that need a strategic buffer from those better planned by conventional methods.
- Document a decoupling point map that shows how independence is achieved across the bill of materials.
02Designing Buffer Profiles and Zones
2 sessions · 8 points
Session 1Buffer Profile Design
- Group items into buffer profiles by shared lead time category, variability category and other planning characteristics.
- Set a lead time factor and variability factor appropriate to each buffer profile group.
- Distinguish a manufactured item's buffer profile from a purchased or distributed item's profile.
- Review buffer profile groupings periodically as lead times or demand variability change.
Session 2Sizing Red, Yellow and Green Zones
- Size the red zone to cover expected variability and protect against stock-out at the decoupling point.
- Size the yellow zone to cover average consumption across the item's replenishment lead time.
- Size the green zone to set an efficient order frequency and order quantity for the item.
- Combine the three zones into a total buffer level that defines the top of buffer stock position.
03Dynamic Adjustment and Demand-Driven Execution
2 sessions · 8 points
Session 1Adjusting Buffers to Changing Conditions
- Apply a planned adjustment factor ahead of a known event such as a promotion, seasonal peak or product phase-out.
- Recalculate buffer zones when a sustained change in average usage or lead time is detected.
- Distinguish a genuine trend that requires buffer adjustment from short-term noise that should be left alone.
- Govern who can approve a manual buffer override outside the standard recalculation cycle.
Session 2Generating and Executing Replenishment Orders
- Calculate net flow position from on-hand stock, open supply and qualified demand at each buffer.
- Generate a replenishment order recommendation when net flow position falls to the order point within the buffer.
- Prioritise open orders and shop floor work using buffer status colour rather than due date alone.
- Use buffer penetration data to decide which open order needs expediting today.
04Governance, Metrics and Rollout
2 sessions · 8 points
Session 1Monitoring Buffer Performance
- Track buffer status distribution across red, yellow and green zones to judge overall system health.
- Investigate an item that spends excessive time deep in the red zone to find its root cause.
- Monitor on-time and in-full performance at decoupling points as the primary service indicator.
- Review flow-based metrics alongside traditional inventory turns to judge the buffer design's effectiveness.
Session 2Rolling Out Demand-Driven Planning
- Pilot demand-driven planning on a limited set of items or a single location before wider rollout.
- Align planning, purchasing and production teams on the new priority signals and daily execution routine.
- Migrate planning system settings and reporting from conventional MRP logic to buffer-based parameters.
- Set a governance cadence that reviews decoupling point selection and buffer sizing as the network changes.
