Purpose, performance, design, responsibility and distinction are not scored independently and then simply added together — a product that performs well but creates real safety or environmental costs cannot outscore its way past that trade-off. Category-specific weighting exists because the right balance differs by category: a kitchen appliance's responsibility considerations (durability, repairability, energy use) carry different real-world weight than a wearable's. This guide walks through how the five dimensions interact in practice, using published category weightings as the reference rather than abstract principle.
