Semi-finished products are classified under which category of muda?

Overproduction
Repair
Inventory
Motion

The correct answer is: Inventory

Semi-finished products are classified under the category of inventory within the framework of muda, which refers to waste in the context of Lean manufacturing. Inventory is considered a type of waste because it represents capital that is tied up in products that are not yet completed or sold. Holding semi-finished products can indicate inefficiencies in the production process, such as imbalances in workflow or processing times, leading to excess inventory that does not add immediate value to the customer. In Lean philosophy, the goal is to minimize unnecessary inventory to enhance flow and reduce lead times. By focusing on reducing inventory waste, organizations can improve their overall efficiency and responsiveness to customer demands. This aligns with the Lean principle of producing only what is needed, when it is needed, to avoid the costs and space requirements associated with excess inventory. Understanding this categorization highlights the importance of optimizing production processes and carefully managing inventory levels to streamline operations and reduce unnecessary costs.
