Which term is a TOC analysis used to map the general flow of components and assemblies using V, A, T, I?

• A. VATI Analysis
• B. Zone
• C. Yokoten
• D. Zone picking

Answer: (A)

VATI analysis in TOC maps the general flow of components and assemblies by evaluating four dimensions: Value added versus non-value-added steps, Availability of components (reliability and lead times), Throughput (the pace at which material moves through the system), and Inventory (where parts sit and how much is held). By laying out a product’s path and scoring each step against these four factors, you get a clear picture of where the flow bottlenecks occur and where delays or excess inventory build up. This visualization helps prioritize improvements that will raise overall throughput.

Other terms mentioned are related to different concepts: zone and zone picking pertain to warehouse layout and picking strategies, while Yokoten refers to cross-department sharing of best practices. They don’t constitute the TOC flow-mapping method described by VATI.
