Every business carries stock, but not all items are equally important. This is where ABC inventory analysis comes in. It helps you sort inventory into three groups, A, B, and C, so you can focus more on what matters most. This method helps reduce costs in operations management while making sure key items are never out of stock.
ABC analysis is based on the Pareto Principle, also known as the 80/20 rule. Typically, about 20% of items account for 80% of a company’s inventory value. These higher-value items become Class A. Meanwhile, Class B items fall in the middle, and Class C includes many low-value products.
Why it matters: Focusing attention on A-items means your team spends time where it counts most. Less critical items don’t need that same level of inventory control.
Here’s a simplified way to do the abc classification in inventory management:
With this, you apply tight control and frequent ordering for A-items, moderate attention for B-items, and minimal handling for C-items
ABC analysis isn’t perfect. Some common drawbacks are:
Here’s a straight-forward abc analysis in inventory management method:
Imagine a small retail store tracking five products. After computing the annual usage value and sorting:
This shows that a few items drive most of the store’s value. You might decide to order Product X more often and monitor it closely. Other items you can review less often.
To make ABC analysis work well, follow these pointers:
This method fits many businesses:
ABC analysis in inventory management helps businesses focus on what matters most. By sorting items into A, B, and C categories, you gain better control, reduce costs, and speed up processes. But remember—it needs good data and regular reviews to stay useful. When used well, it becomes a simple and powerful tool for smooth operations and better profitability.
ABC analysis categorises inventory into three groups: A (high-value), B (medium-value), and C (low-value). It helps prioritise resources by focusing more on high-value items requiring strict control, while lower-value items receive less intensive monitoring.
Inventory is classified by calculating each item’s annual consumption value (unit cost × annual demand), ranking them, and assigning A, B, or C categories. High-value items are monitored more frequently to optimise stock control and reduce carrying costs.
It improves inventory control by focusing on high-value items, reduces storage and holding costs, enhances purchasing efficiency, and helps maintain optimal stock levels without overinvesting in less critical items.
Steps: 1) Identify and list all items, 2) Calculate annual consumption value, 3) Rank items by value, 4) Classify as A (top ~20%), B (next ~30%), and C (lowest ~50%) for control measures.
Challenges include frequent data updates, fluctuating demand, and potential misclassification due to inaccurate records or price changes. Regular review is essential to maintain accuracy.
Annual Consumption Value = Annual Demand × Unit Cost. Items are then ranked based on this value to assign A, B, or C categories.
