# MK-084 | Cross-selling to the same customer group

For a regular chat, upload `packs/mk-084.md`. It includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Related-product recommendation hypotheses for existing buyers**

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. For buyers identified through a role-marker product, prioritize other products needed by people with the same audience characteristics
2. For example, after identifying motorbike riders, consider waterproofing spray, raincoats, gloves, and backpacks. The core is shared role-based needs, not arbitrary cross-selling
3. Validate each follow-on product with shopping-cart, customer-feedback, or behavioral data; a shared role does not guarantee a purchase

## Calculations and interpretation

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

## Required output fields
