ABC analysis: Strategic classification for optimal resource allocation
November 19, 2025
ABC analysis is a proven classification method in Procurement that categorizes items, suppliers or customers according to their economic importance. This method enables buyers to focus resources on the most important elements and set priorities strategically. Find out below how the ABC analysis works, which methods are used and how you can make the best use of this classification for your procurement strategy.
Key Facts
- Classifies objects into three categories: A (high importance), B (medium importance), C (low importance)
- Based on the Pareto principle: 80% of the value is attributable to 20% of the objects
- Typical distribution: A articles 10-20%, B articles 20-30%, C articles 50-70% of the total quantity
- Enables differentiated procurement strategies depending on the item category
- Applicable to articles, suppliers, customers and other business objects

Definition and meaning of ABC analyses
The ABC analysis is a systematic method for categorizing objects according to their relative importance.
Basic principles of classification
The method divides all objects to be analyzed into three main categories based on defined criteria such as value, volume or strategic importance. A objects represent the most important elements with the highest priority, B objects form the middle class with moderate importance, while C objects represent the largest number with the lowest individual importance.
ABC analysis vs. other classification methods
In contrast to more complex evaluation methods, ABC analysis offers a simple but effective solution. While value stream mapping looks at processes in detail, ABC analysis focuses on classifying objects according to a small number of meaningful criteria.
Importance of ABC analysis in Procurement
In procurement management, this method enables resource-optimized management of different article groups. A-items receive intensive support with detailed supplier evaluation, while C-items are handled efficiently through automated processes and high catalog usage.
Measurement, database and calculation
The practical implementation of ABC analysis requires systematic data collection and structured calculation methods.
Data basis and evaluation criteria
Consumption values, annual requirement quantities or sales figures of the objects to be classified are typically used as a basis. The calculation is carried out by multiplying the quantity and individual value, followed by sorting in descending order. Additional criteria such as delivery times or availability can supplement the pure value analysis.
Classification procedure and limit values
After sorting, cumulative percentages are calculated and threshold values are defined. Usual threshold values are 80% for A items, 95% for B items and 100% for C items in relation to the total value. The control intensity varies according to the classification.
Automation and system integration
Modern ERP systems support the automatic calculation and updating of the ABC classification. Integration into procurement processes enables class-specific workflows and helps to improve automated processing.
Tacto Intelligence
Combines deep procurement knowledge with the most powerful AI agents for strong Procurement.
Interpretation and target values for ABC analyses
The ABC analysis is evaluated using specific key figures that measure the effectiveness of the classification and its impact.
Distribution ratios and benchmarks
Typical target values for a balanced ABC distribution are 10-20% A-items (70-80% of the value), 20-30% B-items (15-20% of the value) and 50-70% C-items (5-10% of the value). Deviations from these guideline values may indicate a need for optimization in the product range strategy.
Process efficiency indicators
The order cycle time should vary depending on the class, with A articles justifying longer processing times due to more intensive checking. Catalog usage for C-items should be above 80% in order to realize efficiency gains.
Strategic performance measurement
The share of the purchasing volume controlled by ABC analysis in the total volume(spend under management) should increase continuously. In addition, adherence to delivery dates reveals class-specific differences in the quality of support.
Risks, dependencies and countermeasures
The application of ABC analysis poses specific challenges that need to be addressed with suitable measures.
Static view and market dynamics
Updating the classification too infrequently can lead to outdated priorities if market conditions or demand patterns change. Regular reviews and flexible adjustment cycles are necessary to ensure that the classification is up to date and to avoid strategic mistakes.
One-dimensional valuation
Focusing exclusively on value criteria can overlook important strategic aspects. Critical items with low value but high importance for production may be undervalued. It is therefore advisable to add qualitative factors and risk considerations.
Resource allocation and neglect
The strong focus on A articles can lead to C articles being neglected, even though they offer considerable optimization potential overall. Balanced support concepts and the use of catalog solutions for C articles can counteract this risk.

Practical example
A mechanical engineering company classifies 5,000 articles according to annual consumption value. The analysis shows: 200 A articles (4%) generate 75% of the purchasing volume, 800 B articles (16%) a further 20% and 4,000 C articles (80%) only 5%. The company then implements differentiated procurement strategies: A-items receive weekly stock monitoring and framework agreements, B-items monthly monitoring, C-items are handled via catalog orders with automatic reordering.
- Reduction of processing time by 40% through focused resource allocation
- Improvement in delivery reliability for A-items from 85% to 96
- Cost savings of 12% through optimized C-item procurement
Data and market trends for ABC analyses
The further development of ABC analysis is characterized by digital transformation and expanded analysis options.
AI-supported classification
Artificial intelligence enables dynamic adjustments to classification criteria based on market changes and demand patterns. Machine learning algorithms automatically recognize trends and suggest reclassifications, replacing the traditional static view with adaptive models.
Multi-criteria ABC analysis
In addition to the value criterion, modern approaches take into account additional factors such as supply risk, market dynamics or sustainability aspects. This extended view leads to more differentiated classifications and supports strategic procurement decisions through multidimensional evaluations.
Real-time monitoring and dashboards
Digital platforms provide continuous monitoring of ABC classification with automatic alerts when thresholds are exceeded. The integration of spend analysis enables proactive control and improves responsiveness to market changes.
Conclusion
ABC analysis remains a fundamental tool for strategic procurement decisions and efficient resource allocation. Through systematic classification, it enables focused support for important items while at the same time automating routine processes. The integration of modern technologies and multi-criteria approaches adds dynamic adaptability to the traditional method and increases its strategic value for future-oriented purchasing organizations.
FAQ
What is the difference between ABC analysis and XYZ analysis?
The ABC analysis classifies according to value or importance, while the XYZ analysis looks at the regularity of consumption. X articles have constant consumption, Y articles have fluctuating demand and Z articles have irregular demand. Both methods complement each other perfectly for a comprehensive item classification.
How often should an ABC analysis be updated?
The update frequency depends on the market dynamics. In stable markets, an annual review is sufficient; in volatile conditions, quarterly adjustments are recommended. Automated systems enable continuous monitoring with alert functions in the event of significant changes.
Which criteria are suitable for classification in addition to the value?
Additional criteria include delivery risk, availability, quality requirements, strategic importance and sustainability aspects. Multi-criteria approaches weight different factors and create more balanced classifications than pure value considerations.
How does the ABC analysis influence the supplier strategy?
A-items require intensive supplier relationships with detailed evaluation and regular audits. B items are managed using standardized processes, while C items are often procured via catalog suppliers or e-procurement platforms. The classification therefore determines the intensity of support and contract design.
