What problem does it solve? Product teams often draft Charter documents by copying competitors or filling templates in random order, producing inconsistent business plans. This Skill structures the entire product business case into a 5-column by 3-row matrix and enforces a core-to-outer "long onion" derivation order so every cell logically supports the value proposition. ## Core Features & Use Cases - 5x3 Canvas Generation: Produces a complete matrix covering competitive strategy, product positioning, product solution, GTM plan, and target system across strategic, tactical, and execution layers. - Long Onion Filling Logic: Enforces a mandatory derivation sequence from core battlefield and target users outward to pricing, channels, and cost targets, explicitly banning competitor-copying thinking. - Consistency Checklist: Validates cross-cell logic such as whether selling points support the competitive strategy and whether pricing matches the target audience's purchasing power. - Use Case: A product manager preparing a Charter review workshop for a new smart water bottle uses the Skill to generate the full canvas table, then walks stakeholders through each cell for alignment. ## Quick Start Ask the assistant to generate a business success canvas for your product concept, providing the product category, target users, and core value proposition.
