The official business definition of an Inventory Manager KPI is a set of metrics used to measure the performance of an inventory manager. These KPIs typically focus on the ability of the inventory manager to accurately forecast demand, maintain optimal inventory levels, and ensure that the right products are in the right place at the right time. They also measure the efficiency of the inventory manager in terms of cost, inventory accuracy, and the time it takes to process orders. The KPIs also measure the ability of the inventory manager to effectively manage supplier relationships and ensure that inventory is replenished in a timely manner. By monitoring these KPIs, companies can ensure that their inventory management processes are efficient and cost-effective.
