Key Insights
- The seven powers (the only sources of durable competitive advantage). Helmer’s full taxonomy: (1) Scale Economies, (2) Network Economies, (3) Counter-Positioning, (4) Switching Costs, (5) Branding, (6) Cornered Resource, (7) Process Power. Each creates persistent differential returns — not just temporary advantage. “If your business does not have at least one of these seven Power types, then you lack a viable strategy, and you are vulnerable.”
- Power = Benefit × Barrier. The two-factor test: does this source of advantage create real economic benefit for you, AND does it create a moat (barrier) that prevents competitors from replicating it? A benefit without a barrier is just efficiency. A barrier without a benefit is just friction. When evaluating any strategic move, look for the barrier first: “Always look to the Barrier first.”
- Counter-Positioning — the new entrant’s best weapon. When a superior business model exists that incumbents won’t copy because it would cannibalize their existing business, the new entrant has Counter-Positioning power. The incumbent’s rational self-interest becomes their strategic blindspot. This explains why Netflix beat Blockbuster and why established players often can’t respond to disruptors even when they see them coming.
- Strategy vs. operational effectiveness. Strategy “serves best not as an analytical redoubt, but rather in developing the ‘prepared mind’ of those on the ground.” Operational improvements are table stakes — they don’t create Power. Power comes from structural position, not from doing the same things better.
- Power must be won early — the Statics vs. Dynamics distinction. Static analysis (does a power exist?) is different from dynamic analysis (how did it get created?). Power is typically established during a narrow window — often at launch or at a key inflection — not gradually accumulated. Most companies wait too long to think about which Power they’re building.
- Switching costs are vastly underestimated in B2B. When a customer’s workflows, data, and workflows are embedded in a product, the real cost of switching is multiples of the sticker price of the alternative. This creates durable pricing power — the customer will pay above-competitive margins rather than absorb switching pain.
