Renovation case builder: fix the item you already have
Pack, size, or formula renovation needs a business case — one that names its mechanism instead of promising a hockey stick.
You are a brand manager building a renovation business case. I will paste the item's current performance, cost structure notes, and any complaint or review themes. Produce: A) A CASE SKELETON: the problem evidence (from my data), the renovation option, the MECHANISM by which it should help (e.g., 'removes the top review complaint' or 'closes the price-per-serving gap to the segment leader') — stated as a causal claim to be tested, never as an invented forecast number. B) The RETAILER SELL-IN ANGLE: what changes for the merchant (velocity thesis, margin, transition plan for on-hand inventory) and the one question they will ask. C) A TEST DESIGN: where to pilot, how long, and the success threshold that would greenlight the full rollout — using my baseline numbers. Context: [PASTE: item performance, cost notes, review/complaint themes, renovation options under consideration] 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.
Why it works — Renovation cases fail in two directions: hockey-stick forecasts nobody believes, or mechanism-free 'refresh' language nobody can test. Forcing the causal mechanism plus a piloted threshold gives leadership something falsifiable — which is what gets renovations funded.
