Among the many strategies available for prioritizing inventory management, ABC Analysis definitely stands out as one of the most effective techniques for optimizing inventory control by concentrating more on the resources that matter most in the short and long term.  

This blog, in particular, provides a deep dive into the details of ABC Analysis. It explores the fundamentals, advantages, and disadvantages of implementing ABC analysis in inventory analysis while offering practical tips to integrate it seamlessly into your business operations.

So, no matter if you’re running a retail store, a manufacturing unit, or even a healthcare organization, this short guide will help you understand how implementing ABC Analysis can help you better your entire inventory management practices and thus end up supporting your business goals.

Introduction to ABC Analysis in Inventory Management 

Managing inventory in the correct way is one of the most critical aspects of running any business that manages tangible products. It doesn’t matter that you operate in the retail sector, manufacturing, healthcare, or even the automotive industry, your success in maintaining the right stock levels end up hugely impacting your profits, overall operational efficiency, and even customer satisfaction. 

In such a case, the  ABC Analysis framework serves as a measuring scale for inventory categorization and control. It allows businesses to focus their energy and resources on the items that contribute the most value, ensuring optimal inventory management. By categorizing stock into A, B, and C groups based on their significance, this method empowers businesses to address inefficiencies, minimize waste, and make data-driven decisions.

This blog will break down ABC Analysis for you, into small actionable steps and will  provide you with a comprehensive understanding of how it can be implemented in your business for maximum impact 

What is ABC Analysis? 

The term ABC Analysis owes its origin to the universal and smart rule of thumb of ‘Always Better Control’  and is influenced by the Pareto Principle, which is also known as the 80/20 rule. The Pareto Principle indicates that 80 percent of results from any event/job often come from only the 20 percent of causes/efforts. 

Hence, this suggests that businesses should put in maximum effort in those 20% of areas that provided 80% results, both in terms of profit and customer satisfaction. 

This principle, when seen in the context of inventory management system, means that a small percentage of inventory, typically around 20% items, typically is responsible for a large percentage of value of inventory.

Definition of ABC Analysis  

ABC inventory analysis is a systematic approach to classifying all your SKUs basis their consumption/ sales. The primary motive for performing ABC analysis is to understand the demand distribution of your SKUs so that you can best plan your inventory. The 3 classifications of the ABC analysis are as follows:  

• Category A: Fast-moving SKUs that have a disproportionate contribution to your sales, consumption, and profits. 
• Category B: Moderate-moving SKUs that contribute to a smaller portion of your sales, consumptions and profits. These are nevertheless important to your operations.
• Category C: Slow-moving SKUs that have a very minor contribution to your sales, consumption and profits.

Typically, companies will see the majority of their SKUs fall under Category C, followed by Category B, and finally Category A. This analysis can help you segment your inventory focus and strategies to tackle each category separately. ABC analysis can thus help factories maintain the right amount of inventory while reducing stock-outs or overstocking situations, optimizing inventory costs, sales, production efficiencies, and overall factory profitability.

How Does ABC Analysis Work?

Inventory ABC analysis is a step-by-step approach to categorizing your SKUs as A, B, or C SKUs. This can be done separately for raw materials and finished goods due to their differing nature of inventory consumption. The process is as below: 

Step 1: Data Collection

The primary and most important step for successfully performing the ABC analysis of inventory is to have the right data, such as: 

• Annual Usage: Consumption quantities (production consumption for raw materials and sales quantities for finished goods) of your SKUs over the entire year
• Unit costs: Per unit inventory costs of the SKU
• Inventory levels: Current inventory quantities of all your SKUs (typically the same UoM as consumption)

ABC analysis is best performed with high-quality and accurate data. Factories struggling with their data can consider ERP solutions that can help you track all the relevant data. 

Step 2: Calculate Annual Consumption Value

The next step is to calculate the key metric for categorizing your SKUs, the annual consumption or demand value.

Annual Consumption Value = Annual Usage × Unit Cost (calculated per SKU)

This metric is key for performing ABC analysis as well as understanding the financial contributions of each SKU.

Step 3: Rank Items by Value

The next step in the ABC analysis is to rank all the SKUs basis their annual consumption value. One can add a cumulative % contribution against the sorted SKU list to understand the number of SKUs contributing to 80%, 80-95%, and 95-100% of overall annual consumption values.

Step 4: Categorize Inventory

The final step in the ABC analysis of your inventory is to categorize the SKUs as follows:

• Category A: Represents the top 70-80% of annual consumption value, typically comprising only 10-20% of your SKUs.
• Category B: Representing the next 15-25% of annual consumption value, typically involving 20-30% of SKUs.
• Category C: Representing the remaining 5-10% of annual consumption value but includes 50-70% of total SKUs.

This categorization forms the basis for tailoring inventory management strategies to the unique requirements of each category.

Benefits of Using ABC Analysis for Inventory Control 

ABC analysis is highly effective for optimal inventory management at your factories. Some key inventory benefits of ABC analysis are:

a. Optimized Resource Allocation

By categorizing inventory based on its contribution to consumption/ sales, factories can best allocate inventory resources to SKUs that have higher demands. High-value SKUs in Category A must be keenly monitored to ensure stock-out situations can be minimized. 

Similarly, low-value SKUs in Category C must be monitored to ensure inventory working capital is not tied in an overstocked situation.

b. Improved Inventory Turnover

ABC analysis helps you maintain efficient stock rotation by focusing on high-value SKUs. This approach can reduce excess inventory situations, minimize holding obsolete inventory or dead stock, and ensure that the most valuable SKUs are always available when needed.

c. Strategic Supplier Relationships

For Category A SKUs, factories can build strategic relationships with your key vendors to ensure a lower risk of supply disruptions, minimized volatility of supply lead times, and rapid response of supply to high-demand situations.

d. Cost Savings

By focusing inventory resources on high-value SKUs, ABC analysis can help you reduce your overall inventory costs, thereby saving your factory important working capital. This ensures that your working capital is always available for critical and high-value SKUs to make the most of your high-demand situations.

5. Enhanced Decision-Making

Inventory ABC analysis can help your factory executives make the right data-driven decisions while improving your ability to respond quickly to market requirements. This is extremely helpful for executives looking to make strategic decisions to improve their factory profitability.

Limitations of ABC Analysis 

While ABC Analysis is a powerful technique, it is important to recognize its limitations.

Here are various limitations of ABC Analysis: 

1.Implementation Challenges:

As employees are new to ABC Analysis, they may resist the implementation of the same. Employee training the stern resolve form management are must to implement ABC Analysis successfully.

2.Overemphasis on Financial Value:

As its primary focus is on the monetary value of SKUs, other factors such as perishability, seasonal demand, and operational criticality may get neglected. 

3.Static Categorization: 

On the basis of ABC Analysis, any SKU classification is not permanent. Factors such as changes in market conditions, supplier performance, or SKU demand may force frequent reviews and adjustments, hence making the process slightly complex.

Practical Example of ABC Analysis

To show the real-life practical application of ABC analysis, let’s just consider an example of an Automotive parts manufacturer. Here’s how the company categorizes its SKUs.

The category-wise classification helps the company to prioritize its efforts:

The SKU’s in “Category A” should receive the highest attention, with strict inventory control measures in place. While those in “Category B”  should be monitored regularly but only with relatively moderate control measures. On the other hand, “Category C”  should be handled with only basic monitoring and higher safety stock levels  should be maintained to ensure uninterrupted operations.

ABC vs VED Analysis: Key Differences

While ABC analysis mainly focuses on the core financial value of SKUs, whereas VED Analysis (Vital, Essential, Desirable) on the other hand, gives preference to their specific operational importance. 

Here’s a comparison table for ABC vs VED analysis:

For example, in a hospital setting:

– ABC Analysis would end up prioritizing high-cost SKUs like MRI, PET Scan machines.

–  while the VED Analysis would classify critical drugs as “Vital”, irrespective of their cost.

However, the comprehensive inventory management approach is achieved by combining both ABC Analysis and VED Analysis. 

Conclusion

As discussed in the above blog,  the foundation of the most effective SKU inventory management can be ABC Analysis technique, which gives businesses a structured approach to categorize and controlling their stock. It gives major advantages in terms of cost savings and operational efficiency by focusing on high-value items, improving decision-making, and optimizing resource allocation.

However with the certain limitations of ABC Analysis, hence it should be complemented with other analysis, such as VED Analysis  to give  more holistic inventory management strategy.
