Question

Which of the following is NOT consistent with the lean philosophy?

1) Cross-training employees to increase processing flexibility
2) Developing a culture of continuous improvement within the organization
3) Increasing batch size to take advantage of economies of scale
4) Positioning WIP inventories near each processing center

Answer 1

In lean philosophy, increasing batch size to take advantage of economies of scale is not consistent with the focus on minimizing waste and just-in-time production. Lean philosophy supports cross-training employees, continuous improvement, and positioning WIP inventories to reduce transportation waste.

Step-by-step explanation:

The lean philosophy aims to create maximum value for the customer with minimal waste in the manufacturing process. Under this philosophy, cross-training employees (1) and establishing a culture of continuous improvement (2) are key principles. Cross-training employees enhance flexibility and adaptability, while a continuous improvement culture encourages constant refinement of processes to eliminate waste and improve quality.

However, increasing batch size to take advantage of economies of scale (3) is not consistent with lean philosophy, which focuses on reducing waste through just-in-time production and producing only what is needed when it is needed. Large batch sizes can lead to excess inventory, creating additional waste through overproduction, storage costs, and potential for obsolescence. Lastly, positioning work-in-process (WIP) inventories near each processing center (4) is consistent with the lean approach as it minimizes transportation waste and streamlines the flow of materials.
