D3: Scenario-Based Decision Model - Selection Logic

Overview

Match products to scenarios instead of one-size-fits-all rankings.

Core idea (zh-aligned)

Instead of asking “best overall,” ask “best for scenario.” Scenarios are operationalized needs; they carry weights.

How to apply

1. List 3–5 scenarios (e.g., travel, work, family).
2. For each scenario, define must-haves and weights.
3. Score candidates per scenario.
4. Aggregate across scenarios by scenario importance.
