Which of the following is the key objective of lean manufacturing's focus on non-value-added activities?

• A. Eliminating waste
• B. Increasing production speed only
• C. Reducing energy consumption
• D. Expanding product lines

Answer: (A)

Lean manufacturing aims to remove activities that don’t add value from the customer’s perspective. Non-value-added work takes time and resources but doesn’t change the product in a way the customer would pay for, so the primary objective is to eliminate that waste to improve flow, shorten lead times, and reduce costs. Elimination of waste best captures this focus. Increasing production speed can result from removing waste, but speed alone isn’t the defining aim. Reducing energy consumption and expanding product lines are valuable outcomes in other contexts, but they don’t address the core idea of removing non-value-added activities.
