Definition: Slow-mover analysis – meaning and objective
Slow-mover analysis systematizes the evaluation of stock items with low movement frequency in order to optimize the inventory structure.
Basic characteristics
Slow movers are items that record low or no sales over a defined period of time. The analysis records these items based on quantitative criteria such as inventory range and turnover rate. Typical characteristics include:
- Storage life of over 12 months
- Departure frequency below defined thresholds
- High capital commitment with low added value
Slow-mover analysis vs. ABC analysis
While ABC-XYZ analysis primarily considers value and consumption regularity, slow-mover analysis focuses on movement speed. This complementarity enables differentiated inventory strategies for different item categories.
The importance of slow-mover analysis in Procurement
In strategic procurement management, analysis supports decisions on inventory optimization and supplier consolidation. It identifies potential for reducing capital commitment and improves liquidity management through targeted inventory streamlining.
Methods and procedures
The systematic implementation of a slow-mover analysis requires structured procedures and defined evaluation criteria.
Data acquisition and classification
The analysis begins with the extraction of relevant inventory data from the ERP system. Key parameters include stock levels, outbound movements, and value developments over the last 12-24 months. The inventory analysis categorizes items according to defined criteria:
- Zero movers: No departures in 12+ months
- Slow movers: Departures below minimum frequency
- Seasonal items: Periodic movement patterns
Key figure-based valuation
Quantitative evaluation is carried out using specific KPIs such as stock range, turnover rate, and capital commitment period. These metrics enable measures to be prioritized according to optimization potential and urgency.
Derivation and implementation of measures
Based on the classification, differentiated action strategies are developed. These range from price reductions and marketing campaigns to complete delisting and obsolete inventory disposal.
Tacto Intelligence
Combines deep procurement knowledge with the most powerful AI agents for strong Procurement.
Key KPIs for slow-mover analysis
Specific key figures enable the quantitative evaluation and control of slow-moving inventory in procurement management.
Inventory range and turnover rate
The inventory range in months shows how long the current inventory will last based on average consumption. Values above 12 months indicate potential slow movers. The turnover rate (annual consumption/average inventory) complements this analysis:
- Inventory range > 12 months: suspected slow movers
- Umschlagshäufigkeit < 1: Kritische Kapitalbindung
- Zero movement > 6 months: risk of obsolescence
Capital commitment and performance
The proportion of slow movers in the total inventory value quantifies the optimization potential. This key figure should be monitored regularly and compared with industry benchmarks. In addition, the performance of individual slow-moving items reveals trends.
Sales ratio and utilization rate
The successful reduction of identified slow-movers is measured using sales quotas. This KPI shows the effectiveness of the measures introduced and supports the continuous improvement of the analysis processes.
Risk factors and controls in slow-mover analyses
The implementation of slow-mover analyses involves specific risks that must be minimized through appropriate control mechanisms.
Misclassification and data errors
Incomplete or incorrect master data can lead to incorrect slow-mover identifications. Seasonal items or spare parts with irregular demand may be incorrectly classified as slow movers. Regular data validation and plausibility checks are essential.
Overreaction and deterioration in service levels
Overly aggressive inventory reductions can compromise the level of service. The balance between cost optimization and availability requires careful consideration. Critical spare parts or strategic items require differentiated treatment despite low movement frequency.
Liquidity problems during sales
Reducing slow-moving inventory can lead to liquidity bottlenecks if write-offs or price reductions become necessary. Coordinated planning with the finance department and staggered implementation of measures minimize these risks.

Practical example
A mechanical engineering company identifies 15% of its spare parts inventory as slow movers through systematic slow-mover analysis. The analysis reveals items with a stock range of over 18 months and capital commitment of €2.3 million. The company implements a three-step package of measures: price reductions for A-parts, supplier returns for B-parts, and scrapping for C-parts. After 12 months, capital commitment is reduced by 40%, while the service level remains stable.
- Systematic data analysis covering 24 months of movement history
- Differentiated measures according to ABC classification
- Continuous monitoring of service level development
Current developments and effects
Modern technologies and changing market conditions are shaping the further development of slow-mover analysis in the digital procurement environment.
AI-supported forecasting methods
Artificial intelligence is revolutionizing slow-mover identification through predictive algorithms. Machine learning models analyze complex consumption patterns and identify potential slow movers before they even arise. These consumption forecasting technologies enable proactive inventory management.
Real-time analytics and dashboard integration
Modern ERP systems integrate slow-mover analyses into real-time dashboards. This continuous monitoring replaces periodic evaluations and enables timely responses to inventory changes. Integration with automatic scheduling optimizes procurement processes.
Sustainability aspects and circular economy
Environmental awareness is increasing the focus on avoiding slow-moving items. Companies are developing strategies to conserve resources through optimized inventory management and alternative utilization concepts for slow-moving items.
Conclusion
Slow-mover analysis is an indispensable tool for optimizing inventory structure and reducing capital commitment in modern procurement management. Systematic identification and targeted measures can achieve significant cost savings without jeopardizing supply security. Integration into digital analysis systems and combination with AI-supported forecasting methods reinforce the strategic importance of this method for future-oriented purchasing organizations.
FAQ
What exactly is a slow mover?
A slow mover is an inventory item with a low turnover rate, typically with a shelf life of more than 12 months or a turnover rate of less than 1.0 per year. These items tie up a disproportionate amount of capital while adding little value and require special inventory strategies to optimize storage costs.
How often should a slow-mover analysis be performed?
The frequency of analysis depends on the industry and product range structure. A quarterly full analysis with monthly monitoring of critical items is recommended. Companies with a wide variety of items benefit from continuous monitoring by automated systems that immediately report threshold violations.
What measures are appropriate for identified slow movers?
Measures are selected based on item value and strategic importance. Options include price reductions, marketing campaigns, supplier returns, repurposing for other uses, or controlled scrapping. Despite low movement, critical spare parts often require minimum stock levels to ensure plant availability.
How can you prevent new slow movers from emerging?
Preventive measures include improved demand forecasts, regular assortment reviews, and optimized order quantities. Integrating slow-mover criteria into scheduling parameters and training buyers on inventory risks systematically reduce the emergence of new slow movers. Supplier contracts with return options further minimize the risk of obsolescence.
