Most concepts fail before they ever reach a consumer.

Not because the product is bad. Because the "concept" was never really a concept, it was an ad, a wish list, or a guess dressed up in nice language. This workbook fixes that, one fillable page at a time.

You open a blank page. You know your product. You know your consumer, sort of. But somewhere between the brief and the final concept, things get fuzzy. Insights turn into demographics. Benefits turn into taglines. And by the time it reaches consumer research, nobody can tell you what promise you're actually testing.

This is not another framework you read once and forget.

The Product Concept System is a hands-on Excel workbook with 7 modules, 49 guided questions, and 5 diagnostic tests that walks you from "I have a product idea" to a complete, research-ready concept you could hand to a consumer, a CEO, or an R&D team tomorrow. Built from the exact method used inside 60+ real product launches, at brands like Unilever, Orion, and Tan Hiep Phat.

1. A system, not a template. Most "concept templates" are just empty boxes. This one teaches you the method inside every box — the Why-Because technique for insights, the 4-step translation staircase for product facts, the Incident Room for connecting your raw materials, and more.

2. Built-in honesty checks, not just fill-in-the-blanks. Every module ends with a real diagnostic: the 5-Signal Insight Check, the Competitor Test, the 4 Proposition Tests, the 4 Concept Killers, and the 6-Point Winning Checklist. You'll know exactly when your concept is weak — before a consumer tells you.

3. Built by someone who's done this 60+ times. Written by Ryan Holmes (Đoàn Trung Thảo), a Head of Marketing with 16+ years across Unilever, Tan Hiep Phat, Jupiter Foods, Rooster Beers, and Orion — the same process used to reposition underperforming brands into category leaders.

4. Ready to use today. One Excel file. No software to learn, no account to create. Open it, pick your product on the Start Here tab, and start filling in Module 0.
