Which tool is described as helping to understand the different value streams in lean systems?

• A. Product Family Matrix
• B. Value Stream Maps
• C. FMEA
• D. Hoshin Kanri

Answer: (A)

Understanding how value flows through a lean system is captured by value stream maps. They visualize the end-to-end sequence from raw materials to the customer, showing both the material and information flows, processing times, inventories, and delays. This broad view makes it clear where different value streams exist—for example, where product families take different paths or experience distinct bottlenecks—so you can design a future state that reduces waste and smooths the overall flow. Other tools serve different roles: a Product Family Matrix helps organize products into families for planning, FMEA focuses on identifying and mitigating failure modes, and Hoshin Kanri aligns strategic goals with execution. None of these by itself maps and analyzes the multiple streams of value across a system the way a value stream map does.
