SCM — Supply Chain Management

Supply Chain Management (SCM) covers the end-to-end steering of material, information and financial flows along the supply chain — from raw-material suppliers through in-house production to the end customer. SCM functions are partly integrated into the ERP system, partly delivered by specialised suites such as SAP IBP, Oracle SCM Cloud or Blue Yonder. A solid ERP covers the basics (stock, purchase orders, supplier master data); dedicated SCM tools add forecasting, network optimisation and multi-echelon planning.

SCM vs ERP — what belongs where?

For the classic mid-market in Germany, Switzerland and Austria, the ERP-native modules for procurement, inventory, MRP and logistics are sufficient. Specialised SCM tools become relevant when (a) the supply chain spans multiple plants and countries, (b) item-level demand forecasting is required, or (c) multi-echelon inventory needs to be optimised across the network. In those cases, tools like SAP IBP, Blue Yonder, Kinaxis or o9 supplement the ERP, typically with daily data synchronisation. The break-even point is roughly 200-500 million EUR annual revenue with multi-site operations.

Core functions of an SCM suite

Demand planning: SKU-level forecasting with statistical and ML models, capturing trends, seasonality and promotional effects
Supply planning: multi-stage material and capacity planning across plants, distribution centres and suppliers
Inventory optimisation: multi-echelon stock optimisation that balances service level and working capital
Sales & Operations Planning (S&OP): monthly cross-functional reconciliation of sales forecast, production capacity and financial targets
Network design: strategic plant and warehouse allocation, sourcing-strategy modelling
Risk management: disruption detection, scenario simulation and mitigation planning

SCM KPIs that matter

The most important SCM KPIs: OTIF (On-Time-In-Full) measures whether deliveries arrive on time and complete. Forecast accuracy (ideally above 75% at SKU level for stable products) drives inventory and capacity decisions. Inventory turnover shows how efficiently capital is deployed in stock. Cash-to-cash cycle covers the time between paying suppliers and receiving customer cash. Perfect order rate combines on-time, complete, undamaged and correctly billed. Modern dashboards add ESG KPIs such as CO2 per shipment and sourcing-mix compliance under the German Supply Chain Due Diligence Act (Lieferkettengesetz).

Choosing the right SCM platform

Selection criteria for SCM software include forecast-model breadth (statistical, ML, exception-driven), planning-horizon flexibility (operational daily through strategic multi-year), ERP-integration robustness (real-time or batch), user-experience for planners, scalability to your transaction volume, and TCO over 5-7 years. Leading vendors for the DACH market: SAP IBP for SAP-heavy customers, Blue Yonder for retail and consumer goods, Kinaxis for manufacturing complexity, o9 for upper-mid-market growth, Demand Solutions for entry-level S&OP needs.

Frequently Asked Questions

Do I need SCM software in addition to ERP?

For most mid-market companies, no. Once you have multi-plant or multi-country complexity, need real item-level forecasting, or face high seasonal/promotional variability, dedicated SCM tools become valuable. Below that threshold, the ERP's native procurement, MRP and inventory modules cover the workflow without extra integration cost.

What does an SCM suite cost?

SAP IBP starts around 50 EUR per user per month. Enterprise platforms like Blue Yonder and o9 typically run 200,000 to 500,000 EUR per year for mid-market deployments including implementation. Licence fees are usually 25-35% of total project cost; the remaining 65-75% is implementation, customisation, training and data migration.

Difference between SCM and logistics?

Logistics focuses on the physical flow of materials and goods — transportation, warehousing, delivery. SCM is broader: strategic supply-chain steering including supplier management, demand planning, risk management and sustainability. Logistics is one operational element of SCM, not the whole.
