2. What are some typical inventory metrics you track and how do you use them to improve inventory performance?

Some typical inventory metrics I track include:

  1. Stock turnover rate: This measures how many times inventory is sold and replaced during a period. By tracking this metric, I can identify slow-moving products and make informed decisions about optimizing inventory levels. For example, in my previous role as an inventory manager for a retail company, I noticed that our stock turnover rate for a particular product line was lower than average. By conducting a deeper analysis, we discovered that the slow selling products were due to outdated styles. We then made the decision to discount these products and liquidate them to free up storage space and increase sales of newer products.
  2. Stock accuracy: This metric measures the precision of inventory records against physical inventory counts. I use this metric to identify discrepancies, determine the root causes, and take corrective actions. For instance, in my previous role, I discovered through regular stock accuracy checks that some products were frequently misplaced by warehouse staff. By addressing the training issue and putting in place an updated tracking procedure, we improved our stock accuracy by 25% within six months.
  3. Lead time: This metric is the time it takes from placing an order to when the inventory is received into the warehouse. Tracking lead time helps me to improve inventory performance by ensuring that we have enough inventory to meet customer demand. In my previous role as an inventory manager, I used this metric to identify suppliers that had long delivery periods and switched to those that could deliver in a shorter time frame. This led to a reduction in lead time by 40%, which allowed us to keep fewer days' worth of inventory in storage and resulted in significant cost savings.

By tracking these inventory metrics and regularly analyzing them, I can take data-driven decisions and improve inventory performance significantly.
