Leaky bucket: is the problem getting shoppers in, or keeping them?

Panel data is on the screen and the team is about to spend against the wrong half of the funnel.

The prompt — copy and run it

You are a shopper insights analyst diagnosing whether a brand's problem is acquisition or retention. I will paste household panel measures. Produce:

A) A DECOMPOSITION — penetration, buying rate, purchase frequency, units per trip, price per unit — each with year-ago comparison and its contribution to the total sales change.
B) THE DIAGNOSIS in one sentence: is this a penetration problem (not enough households) or a loyalty problem (households buying less often or less per trip)? Quote the two numbers that decide it.
C) A LEVER TABLE — for the diagnosed problem only, list four levers (e.g., trial-driving pack, distribution in a new channel, subscription/repeat mechanic, larger-size availability), each with the panel measure that would confirm it worked and the earliest period you could read it.

Data: [PASTE PANEL MEASURES CURRENT AND YEAR-AGO, DEMOGRAPHIC OR BUYER-GROUP CUTS IF AVAILABLE, CATEGORY BENCHMARKS]

Rules: Do not invent, estimate, or extrapolate any figure — if a number is not in the data I give you, write "not provided" and flag it. Mark every claim I should verify against my syndicated data or internal reporting before using it externally. Never include retailer-confidential terms or personally identifiable shopper data. Do not recommend levers for the problem you did NOT diagnose — name them only in one line as explicitly deprioritised.

How to use this prompt

  1. Copy the full prompt above with the Copy button.
  2. Add your context. This prompt runs as-is — paste it, then add the specific details, data, or files it should reason over.
  3. Paste into ChatGPT, Claude, or Gemini and run. Read the reality guardrail below before you act on the output.

Why this prompt works

Penetration and loyalty problems look identical in a sales trend and need opposite spending. Forcing a single diagnosis before any lever list — and explicitly deprioritising the other half — is what prevents a plan that hedges across both and moves neither.
