# MK-053 | Launch-price and early-bird-price questionnaire

For a regular chat, upload `packs/mk-053.md`. It includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Questions measuring acceptance of two offers**

Without raw survey responses, produce only a questionnaire or analysis plan; do not fabricate answers

## Required inputs

Provide: Respondents, actual product/bundle, launch and early-bird prices and conditions, scale preference; costs and brand floor for feasibility, not existing responses as a prerequisite for question design

## Method

1. A simplified price questionnaire first explains the product/bundle characteristics fully, then asks about acceptance of the planned launch price and early-bird launch price
2. The course example first requires the planned launch price to maintain a higher contribution margin ratio and the early-bird price to retain a floor ratio, then tests acceptance
3. The survey can use a 1–7-star acceptance scale, but actual prices and bundles must come from real cost planning

## Calculations and interpretation

Check sampling, valid responses, and the ordering of price questions; willingness to pay is neither actual purchasing nor a profit guarantee

## Required output fields

| Order | Field | How to complete |
|---:|---|---|
| 1 | Respondent and product/bundle introduction | Use the supplied source, calculation, or explicit unknown |
| 2 | Launch and early-bird prices and conditions | Use the supplied source, calculation, or explicit unknown |
| 3 | Actual acceptance questions | Use the supplied source, calculation, or explicit unknown |
| 4 | Scale and options | Use the supplied source, calculation, or explicit unknown |
| 5 | Presentation order | Use the supplied source, calculation, or explicit unknown |
| 6 | Cost feasibility and unknowns | Use the supplied source, calculation, or explicit unknown |
| 7 | Survey and response collection method | Use the supplied source, calculation, or explicit unknown |

## Verification cases

**MK-053-A1 | Two real prices/conditions but no responses**

Expected: Draft acceptance questions and scales without requiring prior answers

English translation of source excerpt:

> Van Westendorp's PSM (Price Sensitivity Measurement) fundamentally asks about the target consumer's acceptance of a price. It asks not only whether a price is expensive or cheap, but also which price is "too cheap"
