MK-077 | Product-line depth inventory
For a regular chat, upload packs/mk-077.md. It includes the shared rules, this method, and required references
Purpose
This skill delivers: Tiers, specifications, and price differences within a product category
Products occurring in the same transaction do not establish psychological motives; a product pairing does not automatically prove cross-selling effectiveness
Required inputs
Provide: SKUs, product costs, customer groups, purchase records, and product lines
Method
- Product-line depth examines whether one category offers different tiers, prices, or bundles for audiences with different willingness to pay
- The course material matches different product tiers and prices to different audiences so everyone is not limited to a single price point
- After adding depth, still check costs, willingness to pay, and channels to avoid meaningless internal price competition
Calculations and interpretation
Product selections and next-need proposals are candidates; check inventory, gross margin, existing buyers, and sales data
