# MK-009 | Functional value proposition

For a regular chat, upload `packs/mk-009.md`. It includes the shared rules, this method, and required references

## Purpose

This skill delivers: **One sentence linking a functional problem and its solution**

Separate features, benefits, and evidence; do not claim exclusivity without competitor data

## Required inputs

Provide: Product specifications, competitor differences, verifiable evidence, and intended customers

## Method

1. Use functional jobs in JTBD to answer "What practical task does the customer want to complete, or what problem do they want to solve?"
2. Connect the product's functionality to an achievable task in the value proposition, rather than merely repeating specifications
3. The course material recommends that a good product serve at least a 1+1 combination of functional and social or emotional jobs. Use the functional proposition as a base, then add another layer of value

## Calculations and interpretation

Use only verifiable product differences. Mark claims lacking evidence as needing support; do not generate fabricated evidence

## Required output fields

| Order | Field | How to complete |
|---:|---|---|
| 1 | Feature and evidence | Use the supplied source, calculation, or explicit unknown |
| 2 | Customer job | Use the supplied source, calculation, or explicit unknown |
| 3 | Functional problem | Use the supplied source, calculation, or explicit unknown |
| 4 | How the product addresses it | Use the supplied source, calculation, or explicit unknown |
| 5 | Feature-to-job mapping | Use the supplied source, calculation, or explicit unknown |
| 6 | Complete one-sentence statement | Use the supplied source, calculation, or explicit unknown |
| 7 | Unknowns and validation | Use the supplied source, calculation, or explicit unknown |

## Verification cases

**MK-009-C05 | The specification is true, but no industry comparison data is available**

Expected: Functional benefits may be proposed; do not claim the product is unique or number one

**MK-009-C06 | The information consists only of technical terms**

Expected: Explain their role under the known usage conditions first; do not invent unverified effects
