ABC Analysis Guide
Step 1: Gathering Data
Before launching into the intricacies of an ABC analysis, you need the right data. The first step calls for precision: gather information on the items in your inventory. To collect this data, consider the following actions:
- Identify the Items to be Analyzed: Start by defining the scope of your analysis. Select a particular product line or the whole inventory.
- Collect Sales, Usage, and Cost Data: You need three essential pieces of information:
- The number of units sold or used over a period (usually a year).
- The price of each unit to calculate the total value.
- The cost to procure or produce each unit.
Remember, accuracy at this stage translates to more reliable results later.
Step 2: Calculate Total Value
With your data in hand, it’s time to crunch some numbers. Take each item you’ve gathered data on and calculate the total value using the following formula:
____
Total value = (Cost per unit) x (Number of units sold/used)
____
For example, if a product costs $15 per unit and 1,000 units were sold, the total value for this item would be $15,000.
Step 3: Rank Items
Once you’ve calculated the total value for all items, rank them in descending order from highest to lowest value. This ranking is crucial as it will help identify the items that have the most significant financial impact on your business.
Step 4: Calculate Cumulative Value
Now, it’s time to calculate the cumulative value for each item. Begin by adding the total value of the first item to the total value of the second, then the third, and so on, until all items have been included. This value represents the combined total of top-selling products, allowing you to discern the importance of each item in relation to the whole.
____
Cumulative value = Total value of item 1 + Total value of item 2 + … + Total value of item n
____
Step 5: Determine Categories
Divide the items into three categories, A, B, and C, based on their cumulative value.
- Category A: These items represent the highest value and typically the smallest percentage of the inventory. They are the most critical to monitor closely and might need stricter controls.
- Category B: Moderately valued items that fall in the middle, usually around 20-30% of the inventory value.
- Category C: Relatively low in value, but often the highest in number. They usually form the majority of the inventory, around 50-70%.
Deciding the value or threshold for each category is arbitrary and will depend on the needs and goals of your organization.
Depending on your industry, you may have identified that some products represent a high value while their usage is very low. They may indicate items that are strategically purchased and stored because of their importance, their difficulty in getting replacements, or the consequences if they are not available. These are the products that we identify as “S”, strategic items, a fourth category.
Step 6: Analyze Categories
Understand the implications of each category:
- For Category A items, focus on tight inventory control and supplier management. These items might demand a closer relationship with suppliers to ensure service levels are maintained.
- Category B items might require a more dynamic ordering policy. Your main goal with these items is to establish an ordering strategy that minimizes stockouts and overstocks while maximizing inventory turnover.
- For Category C items, efficiency is key. Large numbers demand efficient storage and handling.
- For Category S items, the same principles than Category A applies, but in addition, these are products that need to be managed tightly regarding their life expectancy. For example, a product that is made of rubber will have a shelf life of approximately 2 years. Having the item in stock and ready for usage requires the product to be below the 2 years. Hence, managing this product with its specifications is essential to ensure that it is available and ready for use when needed.
Step 7: Develop Strategies
Formulate retention and purchase policies for each category:
- For Category A, you might perform frequent cycle counts to ensure that the ERP data is matching the physical data. Another option of to opt for a “just-in-time” approach to procurement to reduce carrying costs. See our article “Just-in-time or Just-in-case procurement?”
- With Category B, employ a periodic review system combined with reorder points to trigger replenishment.
- Category C items often benefit from economic order quantities and periodic review, given they generally have stable usage patterns.
- Category S items will require a frequent validation of their status and availability for usage. Orders will be more sporadic for these items, but understanding the lead time of suppliers will be critical in establishing procurement strategy.
Your strategies should not only consider inventory control but also the broader supply chain and customer demand forecasting.
