Which of the following is a key functionality typically found in a WMS?

A Warehouse Management System (WMS) is primarily designed to optimize and manage warehouse operations. One of its key functionalities is order processing, which involves receiving, picking, packing, shipping, and inventory tracking. This process ensures that orders are fulfilled accurately and efficiently, directly impacting customer satisfaction and operational effectiveness.

In the context of a WMS, order processing integrates with inventory management to facilitate real-time data updates on stock levels, thereby streamlining the workflow within the warehouse. This functionality enables businesses to respond quickly to changes in demand and maintain optimal inventory levels, which is crucial for maintaining the supply chain's overall health.

In contrast, while employee training management, customer relationship management, and financial audits are important business functions, they do not specifically fall under the core operations typically managed by a WMS. Each of those functions is better suited to other systems or modules within a comprehensive enterprise resource planning (ERP) system or HR management system.
