Discuss the ABC classification inventory using a suitable diagram.

ABC classification is a method used in inventory management to categorize items based on their importance and value to the organization. It helps prioritize inventory management efforts by focusing attention on items that have the greatest impact on costs, profitability, and customer satisfaction. The ABC classification divides inventory items into three categories: A, B, and C, based on their contribution to overall inventory value or usage.

Key Concepts:

1. Category A: Category A items are high-value or high-usage items that represent a significant portion of the total inventory value or consumption. Although they may constitute a relatively small percentage of the total number of items, they contribute the most to inventory costs or sales revenue. Examples include top-selling products, high-value components, or critical supplies.

2. Category B: Category B items are moderate-value or moderate-usage items that have a moderate impact on inventory costs or consumption. They typically represent a moderate portion of the total inventory value or usage and require moderate attention in terms of inventory management. Examples include products with steady demand or components with moderate cost.

3. Category C: Category C items are low-value or low-usage items that have minimal impact on inventory costs or consumption. Although they may constitute a large percentage of the total number of items, they contribute relatively little to the total inventory value or usage. Examples include slow-moving items, low-cost components, or incidental supplies.

Diagram:

In the diagram:

• The horizontal axis represents the cumulative percentage of items.
• The vertical axis represents the cumulative percentage of total inventory value or usage.
• The curve represents the Pareto principle, also known as the 80/20 rule, which states that roughly 80% of the effects come from 20% of the causes.
• The items are plotted on the graph based on their individual contribution to the total inventory value or usage.
• The ABC classification divides the items into three categories: A, B, and C, based on their position on the graph. Category A items represent the top 20% of items that contribute to 80% of the total inventory value or usage, Category B items represent the next 30% of items, and Category C items represent the remaining 50% of items.
• The ABC classification helps prioritize inventory management efforts, with Category A items receiving the most attention in terms of monitoring, control, and optimization, followed by Category B and Category C items.
