Hamilton Helmer · 2016
Supplies the strict test: a Power needs a benefit and a barrier. Check the seven honestly. Growth and margin are the benefit, not the barrier.

Michael E. Porter · 1998
Supplies the entrant's view: the classic barriers to entry and the mobility barriers between strategic groups, so you can ask whether copying you would even be rational for the bigger player.
