Point → Line → Plane → Solid (点–线–面–体)

Maps competitive position across four strategic dimensions: Point (one capability, easily copied) → Line (integrated pipeline, integration is the asset) → Plane (platform/ecosystem where others transact, network effects emerge) → Solid (multi-layer reinforcing system — technology, data, network, culture, capital — that requires replicating all layers simultaneously). Answers why some organizations build enduring competitive distance while excellent point-level competitors remain…

How it works

Gate: Confirm the current point-level value proposition is genuinely working before designing dimension elevation.

1. Diagnose the current dimension. Point: one capability, one sentence, directly comparable. Line: reliable integrated sequence, customers cannot decompose and rebuild it. Plane: more users creates more value for existing users; third parties participate. Solid: 4+ co-reinforcing layers (platform + data + brand + network effects + capital). 2. Identify what prevents moving to the next dimension. Point→Line: what adjacent capabilities must be integrated and what blocks it? Line→Plane: what must be true for third parties to participate (density, tools, economics, trust)? Plane→Solid: what additional layers must be added and how do they reinforce each other? 3. Apply the business selection filter. For each candidate path: score on 能 (capability fit) + 想 (organizational desire) + 值得 (economic return) + 该做 (strategic/ethical alignment). Fail multiple criteria = wrong-direction elevation. 4. Design the first concrete transition step. Specific: what is built, acquired, or partnered in the next 90 days. Not "become a platform" — "sign 3 API partners and build the tools they need." 5. Establish the milestone for declaring dimension achievement. "Platform declared when third-party-generated value exceeds 20% of total platform value."

Stop-rule: If the plan skips an intermediate dimension, return to line-building. Each dimension is the structural prerequisite for the next.

When to use it

• user says 'we're good at X but not growing,' 'we need a moat,' 'we're just a feature not a platform,' 'competition keeps copying us,' 'we want to build something hard to replicate,' or asks how to move from product to platform to ecosystem

Worked example

Carnegie Steel's Dimension Progression (1875–1901)

Andrew Carnegie's ascent from single mill to the world's largest private company is the clearest documented application of the point–line–plane–solid progression in industrial history.
