Planning alignment coordinates supply, inventory, and related operational plans between organizations in a supply relationship. The business question is whether partners can move beyond exchanging orders or data and make their plans work together. section 4.3.2
Alignment matters because isolated order decisions amplify distorted demand signals, creating overstocks, shortages, extra costs, and weaker service. Shared demand and inventory data improve forecasts; aligned inventory policies can unlock broader savings. section 4.4
A supply relationship can develop through four increasingly collaborative stages:
- No information: the supplier receives orders without additional client data and must forecast from a distorted order signal. section 4.3.2
- Buying information: external sell-out and inventory data may improve forecasting, but partial, delayed, or poorly aggregated data limits the benefit. section 4.3.2
- Sharing information: clients provide sell-outs, inventory levels, and possibly inventory policies more frequently and with higher quality. section 4.3.2
- Collaboration: partners can progress from sharing information toward planning alignment, including coordination of inventory policies. section 4.3.2 section 4.4
Stable consumption, unstable orders
The Pampers example illustrates the problem: babies consumed a steady flow, yet manufacturing-site orders varied substantially. The beer game offers a hands-on version, with players managing orders and inventory across four echelons while seeing only direct incoming orders. section 4.4 section 4.4
