ABC Analysis in Inventory Control is an inventory categorization method which groups items according to their relative importance. Items are divided into three categories based on predetermined criteria such as usage, price, and turnover. “A” items are the most important and usually consist of a small number of high-value items. These items generally require the most attention from inventory managers. “B” items are less important than A-items but more important than C-items and usually represent 20-40% of total inventory value. Finally, “C” items are the least important items in terms of value or usage, representing the majority of inventory by quantity with minimal monetary value and require the least focus from inventory management teams. ABC Analysis helps inventory managers keep track of all items in stock and focus their efforts on those that have the greatest economic impact.
