Material requirements planning: definition & important aspects for purchasers
.jpeg)
Material planning in a nutshell:
Material planning is the systematic planning, control and monitoring of material stocks to ensure production supply. It is essential for purchasing in order to avoid supply bottlenecks and optimize storage costs at the same time.
Example: An automotive supplier plans its requirements for electronic components three months in advance using an MRP system, whereby a safety stock of 14 days is defined for critical A parts and orders are automatically triggered if the minimum stock level of 1,000 units is not reached.

Introduction to material requirements planning controlling
What is material requirements planning?
Material planning is a central process in procurement management that deals with the planning and control of material requirements. It ensures that all necessary materials are available at the right time, in the right quantity and in the right place in order to guarantee a smooth production process. The core objective of materials planning is to avoid gaps in supply while managing stock levels and costs efficiently.
Core elements of material requirements planning
Significance for purchasing
Material planning is essential for purchasing, as it has a significant impact on the efficiency of the supply chain. Effective materials planning makes it possible to reduce costs, increase delivery capability and improve customer satisfaction. It supports purchasing in making strategic decisions, minimizing risks and achieving competitive advantages through optimized processes.
Guideline: Optimizing materials planning for efficient warehousing and inventory management
Effective material planning in practice
Material planning controls the timely provision of materials to ensure a smooth production process. It takes into account demand forecasts, stock levels and delivery times in order to determine optimum order quantities and times.
Practical example
Example of a production company:
Initial situation: A manufacturer of electronic devices plans to produce 10,000 smartphones in the next quarter. Two batteries are required for each smartphone - one for the device and one as a replacement.
Demand planning:
Inventory check:
Order quantity determination:
Delivery time and order date:
Order processing:
Supplier coordination:
Through this process, the buyer ensures that enough batteries are available at the right time without building up unnecessarily high stock levels. This optimizes costs and minimizes the risk of production interruptions.
Evaluation and strategic findings
✓ Critical success factors
→ Integrated system landscape: close integration of ERP, MRP and production planning for precise demand forecasts
→ Supplier relationships: Building strategic partnerships with key suppliers for flexible supply agreements
→ Process automation: implementation of automated scheduling systems to reduce manual intervention
⚠ Challenges and limitations
→ Fluctuations in demand: Volatile markets make precise forecasts and inventory optimization difficult
→ Complexity management: Increasing variant diversity and shorter product life cycles increase scheduling costs
→ Global supply chains: longer delivery times and higher risks require adapted safety stocks
Future trends and strategic implications:
"The digital transformation enables the transition from reactive to predictive material planning."
→ AI-based demand forecasts for greater forecasting accuracy
→ Digital Twins for the simulation of scheduling scenarios
→ Blockchain-based transparency in the supply chain
→ Real-time optimization through IoT sensor data
◆ Recommendations for action
→ Investment in advanced analytics for improved forecasting capability
→ Establishment of robust risk management for supply chains
→ Development of hybrid disposition strategies for different material groups
Conclusion on material planning
Materials planning is an indispensable tool in modern procurement management. It combines strategic planning with operational implementation and ensures an optimal flow of materials through precise determination of requirements, intelligent inventory management and close supplier coordination. Success lies in the balance between security of supply and cost efficiency. With increasing digitalization and AI-supported solutions, materials planning is becoming even more precise and sustainable.
