3 Common Inventory Management ‘Sins’—And How to Avoid Them
ARTICLE SUMMARY Three rules are really important in inventory management. If you don’t get them right, you won’t be able to do a lot of other things. They are: 1) Observe ABC Classification It has long been shown that 20 percent of lines account for 80 percent of revenue and margin. These are the A-lines and should be prioritised in the warehouse. The B-lines and C-lines contribute less to revenue so they should not be treated in the same way as the A-lines. 2) Forecast Demand If you fail to forecast demand, you face the following potential risks: Running out of stockExcess inventoryObsolescence expenseHidden costs. 3) Draft an Inventory Policy If you don’t have an inventory policy: 1) You won’t get consensus 2) Cause and effect will be hard to pin down 3) Systems can’t be set up 4) Comparisons will be impossible.

Number of lines 4,052. Percentage of lines 58%. As we work down the lines we see an ever-decreasing contribution to revenue.
