What is ABC Analysis?

ABC analysis is a method of categorization of inventory based on significance and importance of the items in the production process which determines the level of inventory control. It is defined as a method of classifying clients, events, inventory, items or activities according to their relative significance and deciding upon this fact that on the extent of importance, consideration and control one should put on this analysis under such classifications. ABC Analysis comes under the purview of inventory management.

Importance of ABC Classification

It’s a ranking system where items are grouped according to their usefulness in achieving in business goals. This system requires grouping of things into 3 different categories:

A – Most Important

B – Very Important

C – Important

ABC Analysis

Purpose of doing this ABC classification is identifying things which effect output the most. Low variation in these things can lead to high changes in output. Thus these things are closely monitored thus helping organizations to increase their efficiency.

As A category things are more important more attention is given to A and relatively less to B and C. One should use it for selection of a restricted number of tasks or clients because it produces significant overall result or profit. It basically uses the idea that by doing 20% of effort, 80% of the gain of doing the entire work can be generated. For many events, about 80% of the things come from 20% of the causes.

This analysis works under the assumption that all inventories are not of equal value to the organization so they need to be treated differently.  A typical ABC analysis classifies the inventory based on the following table.

Type of Inventory

Type of Importance

Type of control

A Items

Very Important

Accurate records, very tight control

B Items

Little less important

Decent records, a little less tight control

C Items

Marginally important

Only essential records, light controls

Typically “A items” consist of minimum amount of items but these items account for a major proportion of value for the organization and so on with the other items.

Advantages & Disadvantages of ABC Analysis

Some advantages are:

1. Better control on expensive items on which large investment is required

2. Cycle counting, which is an indicator of stock replenishment can be effectively used after completing the grouping

3. Ensures reduction in storage expenses


However, some of the drawbacks of this method are:

1. This method can’t be employed where products can’t be standardized

2. Classification is done purely on the basis of monetary value and other factors are ignored

3. A good system to codify the products should be used in order to perform the ABC analysis


Example of ABC Analysis

In an inventory management system we can categorize products into ABC classification depending upon their annual sale or percentage sale of the items. High selling items should be categorized as A and managing their inventory should be top priority of inventory management team. A group of items might only be 20% of various types of products available but their business importance or contribution to revenue is 80%.
