ABC XYZ Analysis

Let's talk about ABC and XYZ analysis.


Effective inventory planning is crucial for businesses to optimize resources, manage costs, and meet customer demands. ABC and XYZ analysis are two popular frameworks used to categorize products based on different criteria, enabling businesses to implement tailored planning strategies. In this blog post, we will delve into the world of ABC and XYZ analysis, understanding their significance and how they aid in efficient planning. Let's get started!

ABC Analysis: Categorizing by Sales Revenue The ABC analysis categorizes products based on their sales revenue contribution. By segmenting products into three groups (A, B, and C), businesses gain insights into the significance of each product in their portfolio.

  • A Category: This includes products that generate the top 70% of sales revenue. These high-value items often require close monitoring and proactive management to ensure their availability and meet customer demands.

  • B Category: The next 25% of products fall into the B category. While they contribute to the overall revenue, they may not have the same impact as the A category products. These items require a balanced approach to planning and inventory management.

  • C Category: The remaining 5% of products fall into the C category, representing those with lower sales revenue contribution. These items typically have a lower impact on the business's bottom line and may require a different planning approach to avoid excessive inventory holding costs.

By understanding the revenue significance of each product, businesses can allocate appropriate resources and implement customized planning strategies.

XYZ Analysis: Categorizing by Demand Uncertainty The XYZ analysis categorizes products based on the level of demand uncertainty they exhibit. It helps identify the appropriate forecasting and planning methods for different product categories.

  • X Category: This category represents products with the least uncertain demand. They exhibit relatively stable demand patterns

  • Y Category: Products in the Y category have moderate demand uncertainty.

  • Z Category: The Z category represents products with the most uncertain demand. These items often have sporadic or highly volatile demand patterns.

By putting these 2 frameworks together, we get 9 categories. AX, AY, AZ, BX, BY, BZ, CX, CY, CZ.

AX category requires the use of simple forecasting methods, e.g. the moving average; it also requires a high level of intervention from human demand planners. AZ category requires the use of more advanced forecasting methods and also requires a high level of intervention from human planners. CX category requires simple forecasting methods with little to no human intervention. And finally, the CZ category should require the least amount of effort either by human or technology. These can be planned by setting a safety stock level and placing replenishment orders once the stock levels fall below a predefined level.


Implementing ABC and XYZ analysis empowers businesses to optimize their inventory planning by categorizing products based on sales revenue and demand uncertainty. By understanding the significance of each product and the level of uncertainty it entails, businesses can align their planning methods and allocate resources effectively.

Take a moment to assess your product portfolio and identify which products fall into the A, B, or C categories in terms of sales revenue. Additionally, consider the demand characteristics of your products and categorize them as X, Y, or Z based on demand uncertainty.

With this valuable insight, you can develop targeted planning strategies, optimize inventory levels, and ensure efficient supply chain operations. Leverage the power of ABC and XYZ analysis to streamline your planning processes and drive success in your business.
