Final answer:
The incorrect advantage of Kanban listed is 'Eliminates inventory management.' Kanban does not eliminate inventory management but helps control and optimize it, while also providing other benefits such as improved quality control and reduced inventory costs.
Step-by-step explanation:
The subject of this question pertains to the Kanban system, which is used in inventory management and process improvement, particularly in manufacturing and production environments. Kanban is a component of just-in-time (JIT) systems, like the one utilized by automobile manufacturers such as Honda in the 1980s.
One of the options provided as an advantage of Kanban is incorrect: 'a. Eliminates inventory management'. This is not an advantage of Kanban because Kanban does not eliminate the need for inventory management; rather, it is a system that helps to control and optimize inventory levels.
Instead, Kanban provides several advantages, such as allowing for a limited amount of defective or delayed material (option b), making problems immediately evident since quality issues are detected quickly (option c), and exerting downward pressure on the less desirable aspects of maintaining inventory (option d).
These benefits of Kanban lead to improved quality control in production and supply chain processes, and discourage the accumulation of excess inventory which can be costly and inefficient.
