# MK-015 | Customer-clue inventory

For a regular chat, upload `packs/mk-015.md`. It includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Separate columns for raw clues, sources, knowns, and unknowns**

Hypotheses are useful but do not establish demographics or market share; do not fabricate interview content or customer experiences

## Required inputs

Provide: Product facts, existing customer data, surveys, or customer-service records

## Method

1. Gather clues such as product images/pages/Sales Kits, three USPs, price, purchase frequency, and existing customer/audience data
2. Give the AI and team a shared view of the product before moving to Persona work
3. Separate facts, brand assumptions, and consumer hypotheses awaiting validation; do not mix AI estimates into customer facts

## Calculations and interpretation

Treat customer roles and motivations as hypotheses initially; do not establish someone's actual identity from a single purchase behavior

## Required output fields

| Order | Field | How to complete |
|---:|---|---|
| 1 | Hypothesized group | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 2 | Buying/using role | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 3 | Trigger situation | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 4 | Tasks and concerns | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 5 | Supporting clues | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 6 | Counterexamples | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 7 | Items to validate | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 8 | Suitable message | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |

## Verification cases

**MK-015-C05 | An order contains maternity and baby products**

Expected: Do not immediately identify the buyer as a mother; separate the buying and using roles

**MK-015-C06 | Different clues support two situations**

Expected: Keep both candidates and request the data that would distinguish them
