Inventory optimisation in 3 steps: forecast, optimisation, procurement.

The key points

  • Inventory optimisation runs in three steps: forecast demand, optimise parameters, execute orders.
  • The forecast determines what you expect. The optimisation determines safety stock, reorder point and quantity per article.
  • Procurement turns that into order proposals that your purchasing only has to approve.
  • Anyone who starts at the third step and just orders faster is optimising symptoms: the order is the point.

Step 1: how does a usable forecast emerge?

The basis is consumption history per article: 12 to 24 months, cleaned of outliers like one-off orders. On top of that, forecasting methods compute that detect trend, season and demand patterns. What matters is less the method than data hygiene: a forecast on unmaintained master data is noise with decimal places.

Step 2: what does optimisation concretely mean?

From forecast, lead time and target service level, the parameters per article emerge: safety stock, reorder point, order quantity. The calculations behind them are textbook. Optimisation means not setting these values once, but continuously updating them: classification, lifecycle and demand change.

Step 3: how does the optimisation reach day-to-day work?

The last step translates parameters into order proposals: which article, which quantity, from which supplier, today or next week. Your purchasing checks exceptions instead of every item. How such a proposal emerges is shown by the article on replenishment.

The most common shortcut is the most expensive: starting straight at step 3 and just ordering faster. Without forecast and parameters you order the same wrong inventory, just more efficiently.
