The short answer
The short answer
Hamilton Helmer's Seven Powers describes seven potential mechanisms of durable business advantage: scale economies, network economies, counter-positioning, switching costs, branding, cornered resource, and process power. Each requires both a benefit and a barrier to competitors. The framework is not a checklist on which a business should claim every power.
01
What distinguishes the seven mechanisms?
Scale economies can reduce unit costs as volume grows. Network economies can increase value to users as participation grows. Counter-positioning describes a business model an incumbent faces damaging trade-offs in adopting. Switching costs make changing providers costly. Branding can support value through customer associations. A cornered resource involves preferential access to a valuable scarce asset. Process power arises from embedded routines competitors cannot readily reproduce.
A large audience is not automatically a network effect. Familiarity is not automatically pricing power. A documented process is not automatically process power. Identify the benefit, the barrier, and the customer or economic evidence.
02
How does Seven Powers work with VRIO?
VRIO tests particular resources; Seven Powers asks which mechanism could sustain attractive economics. Together they help a business distinguish its candidate advantage from supporting infrastructure and unsupported claims.
Use focused tests rather than assigning an invented overall power score. An established advantage can weaken as customer needs or competitive capabilities change.
Further clarity
Questions owners ask
Does an endorsement network establish network economies?
Not by itself. Relationships may create credibility or privileged insight without increasing value to each participant as more participants join. Those benefits can be important but should be described accurately.
