This skill provides the complete methodology for retail category product structure analysis and category management, integrating two complementary knowledge systems: ① 零售学堂 (methodology frameworks: product configuration theory, retail mathematics, category management, demystification philosophy) and ② 零售数据化企划/零售老刘 (quantitative modeling: category modeling series, dual ABC, price band analysis, metrics system, entropy framework). It should be used when the user asks to analyze supermarket or retail category structures, perform category management, ABC analysis, evaluate product configurations, diagnose price and variety structures, do 52-week MD planning, or develop data-driven category optimization plans. The skill requires confirming the store format (convenience store, supermarket, hypermarket, etc.) before analysis, and incorporates real-time market trend research and industry benchmark data (Mashangying platform) as external references alongside internal data analysis. It covers: ABC analysis, dual ABC classification, IPC price structure modeling, HS variety matrix, hierarchy proportion analysis, shopping basket analysis, 52-week MD methodology (week dimensions, customer purchase cycles, narrative structure), fresh produce specialty analysis (pork/fruit/vegetables plus wide-class narrow-product model and bustle atmosphere concept), database extraction guidance for Kemai Yushang+ ERP, barcode classification verification, SKU constraint calculation (7 internal constraints), the 4S principle, KVC/KVI price impression management, LOSS dual structure analysis, demand-entropy framework as retail's universal logic, and the full category management workflow with demystification methodology.
