Question 1 of 143
The use of station warning lights, tool boards and jidohka devices in the application of Lean accomplish which of these principles?
Correct Answer: B

The use of station warning lights, tool boards, and jidohka devices in Lean manufacturing is primarily aimed at creating a Visual Factory. These tools are used to make the status of the production process visible and easily understandable to all workers, thereby enhancing communication and efficiency. This helps in quickly identifying abnormalities and ensuring that corrective actions can be taken promptly.

Question 2 of 143
A Lean Principle that addresses efficiency by the process worker is called ____________________?
Correct Answer: D

The Lean Principle that addresses efficiency by the process worker is called standardizing. Standardizing involves creating consistent methods and procedures to ensure tasks are performed efficiently and effectively, reducing variation and waste, and thereby improving overall process efficiency.

Question 3 of 143
While management of a company must set the stage for all improvement efforts, which of these 5S’s is primarily driven by management?
Correct Answer: D

Sustain is the step of the 5S methodology that involves maintaining and reviewing standards. It is primarily driven by management because it requires their commitment to creating and enforcing policies that ensure the ongoing adherence to the 5S standards. Sustaining 5S practices involves continuous monitoring, training, and support from management to make sure that all other steps (Sort, Straighten, Shine, Standardize) are consistently followed over time.

Question 4 of 143
As part of a Visual Factory plan __________ cards are created and utilized to identify areas in need of cleaning and organization.
Correct Answer: B

Kaizen cards are utilized as part of a Visual Factory plan to identify areas that need cleaning and organization. Kaizen refers to continuous improvement involving everyone, from the management to workers. It focuses on small, incremental changes rather than large-scale sweeps, often highlighting issues that need attention like cleanliness and organization.

Question 5 of 143
The use of Kanbans work best with pull systems for determining the timing of which products or services are produced.
Correct Answer: A

Kanban is a scheduling system for lean and just-in-time production, which inherently works best with pull systems. In a pull system, production is based on actual consumption rather than forecasted demand, and Kanbans are used to signal the need to move materials, objects, and parts through the production process. Therefore, the statement is true.
