In order to eliminate waste, companies must adopt and implement one or more management practices that focus on different aspects of the lean business model such as:

A) maintaining inventories large enough to shield against all unanticipated disruptions.
B) Just-in-Time.
C) Activity-Based Costing.
D) multi-dimensional performance measurement systems.

Just-in-Time (JIT) is a management practice that focuses on reducing waste by producing and delivering products or services just in time when they are needed, rather than maintaining large inventories. This practice minimizes the cost of inventory and storage space, reduces the risk of inventory becoming obsolete, and increases the speed of delivery. JIT also helps to identify inefficiencies in the production process and improve the quality of the final product. Therefore, JIT can be a useful management practice for companies that are trying to eliminate waste and improve efficiency.
