Jeans are underperforming on a marketplace. 1) Design an analysis to diagnose whether the bottleneck is demand or supply using: CTR on jeans ads/searches, search sessions with filters applied, session time, conversion given search, conversion given filter use, and price‑band coverage. 2) Define a quantitative decision rule (with thresholds) that classifies the category as demand‑limited or supply‑limited using funnel ratios like Conversions/Searches and Filter‑Use×Low‑Conversion flags. 3) Propose follow‑up experiments or interventions for each diagnosis (e.g., better retrieval/ranking and intent capture for demand; assortment/price changes, seller tooling, or subsidized shipping for supply) and how you will measure success without cannibalizing adjacent categories.
