Which of the following is a characteristic of lean manufacturing that may not align with its principles?

• A. Idle workers
• B. Centralized management control
• C. Mass production
• D. Excess Inventory

Answer: (B)

Lean manufacturing centers on empowering those closest to the work to make decisions and quickly respond to problems, creating smooth flow and reducing waste. Centralized management control clashes with this approach because it concentrates authority away from the people who actually see the process, causing delays, bottlenecks, and slower improvement cycles. When decisions must go up a chain of command, problems on the line can’t be addressed promptly, undermining the pull-based, just-in-time mindset that lean relies on. This is why centralized control is the characteristic that may not align with lean principles.

Idle workers, mass production, and excess inventory are also wastes that lean aims to minimize, so they don’t reflect lean practice. They illustrate outcomes lean seeks to prevent rather than traits that fit lean.
