Why is important:
Is your attention focused on the most valuable products (Category A)? The ones that contribute the most to your profits or sales? Do you manage relaxed the less critical items (Categories B and C)? ABC classification it’s like prioritizing your most important tasks to maximize impact!
Our offer:
Provide you a report with ABC classification and share possible insights regarding your products. You will have an opinion on:
- What are most valuable items
- How can your inventory management & cash flow can be improved
- What items could be removed from your future offer/assortment
- Where to keep an eye on "on shelf availability" to secure customer satisfaction
Depending on data available the value and quality of the insights can be fined tuned based on:
- Date of first sale of a product (exclude from analysis the new products)
- Date of last delivery or no-longer-active products (exclude from analysis obsolete products)
Do it yourself (simplified version) ⬇️⬇️⬇️
Preparation Time: 2–3 hours
Skill Level: Beginner-Friendly
Ingredients:
- Simple Inventory Data organized per columns with a clear axis of analysis in mind (eg: sales, quantity or profit)
- Tools: Spreadsheet software (Excel/Google Sheets).
- Skills: Basic understanding of percentages & familiarity with sorting and cumulative calculations.
Step 1: Gather and Prepare Your Ingredients
-
Collect your inventory data. Ensure your dataset includes:
- A unique identifier for each inventory item (SKU code)
- Total sales, quantity, profit or similar per a period of time (month or year); to our demonstration we will use a generic term of Total Value
- Optional you may add: Date of first sale, Date of last delivery/purchase.
-
Ensure data is clean.
- No duplicates;
- Missing values are addressed.
Step 2: Arrange the Ingredients
Add to the table with these columns:
-
- Percentage of Total Value (to be calculated).
- Cumulative Percentage of Total Value (to be calculated).
- Category (to be assigned).
Step 3: Cook Up the ABC Analysis
- Sort the inventory. (Arrange items in descending order by their Total Value.)
- Calculate field "Cumulative Percentage of Total Value" for each item. Formula for each item = item Total Value / sum (all items Total Value)
× 100
. - Calculate field "Cumulative Percentage of Total Value"
- First item (top line) = Cumulative Percentage of Total Value for the item;
- For subsequent fields, add the percentage from each item in sequence: Cumulative Percentage (Row N) = Percentage of Total Value (Row N) + Cumulative Percentage of Total Value (Row N-1).
Step 4: Serve the ABC Categories
Classify your inventory into A, B, and C categories:
- Category A: Items contributing to the top 70% of total value.
- Category B: Items contributing the next 20%.
- Category C: Items contributing the final 10%.
Assign categories based on the Cumulative Percentage of Total Usage Value:
-
-
- Items with a cumulative percentage ≤ 80% → Category A.
- Items with a cumulative percentage > 80% but ≤ 90% → Category B.
- Items with a cumulative percentage > 90% → Category C.
-
Highlight the rows with different colors for each category (optional, for visual clarity).
Step 5: Taste Test (Review the Results)
- Check the classification. Does it align with the typical Pareto Principle (80/20 rule)? Are there outliers or anomalies worth investigating?
- Refine if necessary. Adjust thresholds if needed to suit specific business requirements.
Serving Suggestions
- Present results in a bar graph showing cumulative percentages or a pie chart showing category contributions.
- Use the analysis to prioritize inventory management efforts:
- Focus on Category A for stock optimization.
- Review reorder strategies for Category B.
- Apply less stringent controls for Category C.
Bon appétit in data-driven decision-making!
