# MK-087 | Premium-bundle upgrade design

For a regular chat, upload `packs/mk-087.md`. It includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Offers differentiated by functionality, specifications, or service**

Products occurring in the same transaction do not establish psychological motives; a product pairing does not automatically prove cross-selling effectiveness

## Required inputs

Provide: SKU, costs, current and upgraded offers, comparable market data, audience willingness-to-pay or choice evidence, stock and fulfillment conditions

## Method

1. Premium upgrades can use different product tiers and prices to serve audiences with different willingness to pay
2. Packaging, IP collaborations, bundles, and a new value framing can also increase willingness to pay, instead of simply charging more for the same product
3. After upgrading, recheck the market, audience value, and costs to confirm the change adds corresponding value rather than costs alone

## Calculations and interpretation

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

## Required output fields

| Order | Field | How to complete |
|---:|---|---|
| 1 | Goal | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 2 | Audience | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 3 | Plan/task | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 4 | Evidence and assumptions | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 5 | Prerequisites | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 6 | Resources | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 7 | Deliverables and acceptance | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 8 | Open issues | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |

## Verification cases

**MK-087-C05 | The budget is unknown, but materials can be organized first**

Expected: Deliver the parts of the plan that do not depend on the budget first; do not require a complete questionnaire
