# MK-091 | Product-mix gap diagnosis

For a regular chat, upload `packs/mk-091.md`. It includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Imbalances between traffic-driving and profit-generating roles**

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

1. First check that the product line includes roles such as first contact/traffic-driving or trial, core/member benefits, and high-margin/repeat purchase
2. Then check whether the same shared audience can progress from its first purchase to another brand product, instead of buying traffic again each time
3. If product-development capability is missing, use knowledge products to qualify audiences first. If a first-purchase entry point is missing, prioritize traffic-driving/trial products. If repeat-purchase progression is missing, add core/high-margin products and reminders

## Calculations and interpretation

Product selections and next-need proposals are candidates; check inventory, gross margin, existing buyers, and sales data
