ניתוח ABC

ABC analysis divides inventory into three categories based on value and importance. Category A includes high-value items that are few in number but contribute significantly to total inventory value. Category B consists of moderate-value items requiring moderate attention. Category C includes numerous low-value items that contribute little to overall value but can be managed with minimal oversight.

Category A items require strict control and regular monitoring because they represent a large portion of total inventory value despite being few in number. By prioritizing high-value items, businesses can control inventory costs and improve efficiency. This focus allows resources to be allocated where they have the greatest financial impact on operations.

ABC analysis segments inventory based on the Pareto Principle, which suggests that a small percentage of inputs often accounts for a large percentage of outcomes. In inventory management, this means a small fraction of items typically represents the bulk of inventory cost. This principle justifies concentrating management efforts on high-value Category A items.

High-value Category A items may require techniques like just-in-time inventory or safety stock optimization to minimize carrying costs. Category B items are managed with moderate intensity. Category C items, being numerous but inexpensive, can be ordered in bulk to minimize administrative effort and reduce ordering frequency.

ABC analysis provides a practical framework for budgeting, supplier negotiations, and risk management by aligning control efforts with financial impact. When combined with demand forecasting and lead time analysis, it forms a key part of modern inventory strategy. This method helps businesses balance service levels with inventory carrying costs effectively.

In a parts distribution company, industrial bearings might fall into Category A due to high unit cost and steady demand, even though there are only a few SKUs. Washers and screws may be classified as Category C because they are abundant and inexpensive, yet individually contribute little to total inventory value.

ABC analysis enables retailers to apply different management intensities based on product value. For example, a store with one hundred products might focus strict control on ten Category A items generating eighty percent of sales value, apply moderate attention to twenty Category B items, and use minimal oversight for seventy Category C items generating minimal revenue.
