Power = benefit + barrier
What is Power = benefit + barrier?
Helmer: Power is the set of conditions creating the potential for persistent differential returns. It requires both a Benefit (something that materially improves cash flow — higher price, lower cost, less investment) and a Barrier (something that prevents competitors from arbitraging that benefit away). Most 'strengths' are benefits without barriers.
How Power = benefit + barrier works
The barrier is the non-obvious half. The test for every concept in this layer: what specifically stops a rational, well-resourced competitor from copying the benefit?
The question to ask of a company
Against which rival, in which period and customer segment, does this advantage improve cash flow? State benefit, barrier, evidence and a counterexample; distinguish an entry advantage from a durable moat.
Examples
- A great engineering team is a benefit without a barrier — competitors can hire.
- Low prices are a benefit without a barrier unless backed by Scale economies.
Who names it — 4 of the canon
| Author | What they call it / where it appears |
|---|---|
| Helmer | Power; Benefit + Barrier; 'strategy is a route to continuing Power' |
| Neumann | Moat: a mechanism that lets an innovator keep some of the value it created |
| Porter | Sustainable competitive advantage |
| NFX | Defensibility |
Note. A successful strategy can include valuable but temporary product or execution advantages. Record these without relabeling each as Power. Retention supports persistence but cannot explain initial acquisition or isolate switching costs from satisfaction.
