Final answer:
The best method to understand the movement of material through the machine shop and reduce non-value-added activities and delays is to implement Lean Manufacturing principles.
Step-by-step explanation:
The best method to use in order to understand the movement of material through the machine shop and reduce non-value-added activities and delays is to implement Lean Manufacturing principles. Lean Manufacturing focuses on eliminating waste, improving flow, and maximizing value for the customer. By mapping the current state of the production process, identifying bottlenecks and non-value-added activities, and implementing strategies such as cell manufacturing, kanban systems, and continuous improvement, the machine shop can achieve a more efficient flow of material.
