Inventory Management and ABC Classification
Not all items in the warehouse are created equal. Trying to manage all stock with the same sensitivity is the mathematical definition of risking the company's core capital by wasting energy on low-value parts.
Inventory (stock) management is the art of balancing the blood flow in the arteries of a factory. Keeping more goods in the warehouse than necessary means freezing the company's cash on shelves (tied-up capital); while working with insufficient stock leads to the production line stopping and the loss of customers. Professional inventory engineering aims to walk that thin, optimum line between these two extremes. An algorithmic system built by considering the turnover rates, shelf lives, and lead times of products ensures that the warehouse is not just a storage area, but a competitive weapon of the company.
ABC classification (a derivative of Pareto analysis) is the most rational method used to manage this complex structure. Thousands of items in the warehouse are sorted not randomly, but according to the value they add to the company. "A" class products are critical and expensive parts that make up 80% of the total stock value despite being low in quantity (20%); therefore, they are counted daily and managed with zero error tolerance. "C" class products (bolts, packaging, etc.), although taking up most of the warehouse volume, have very low financial value; for these, management energy is optimized using more flexible, automatic order triggers (Reorder point).
