What is the purpose of value-stream mapping in lean manufacturing?

• A. The purpose is to identify waste and improve process flow across the value chain.
• B. The purpose is to set marketing budgets.
• C. The purpose is to estimate final product pricing.
• D. The purpose is to train employees in leadership.

Answer: (B)

Value-stream mapping is a Lean practice that visualizes the end-to-end flow of a product or service—from raw materials to customer delivery—showing both material and information flows. The main aim is to identify waste and improve process flow across the value chain. By capturing every step, wait time, handoff, and decision point, teams can see non-value-added activities and bottlenecks, measure current cycle times, and design a future state that eliminates waste, reduces lead times, and smooths flow with improvements like pull systems and one-piece flow. This helps coordinate across departments so value is delivered to customers faster and with less waste. Marketing budgets, product pricing estimates, and leadership training are not the focus of value-stream mapping; this technique concentrates on process efficiency and waste elimination.
