Reach value, not merely finish setup
Creating an account is a conversion, but it does not mean the product has helped yet. In a collaboration tool, inviting a colleague and completing a first shared task might count as activation.
The “aha moment” is when the product’s value becomes clear to someone. A team cannot measure that feeling directly, so it chooses an activation event: an action that suggests the user has reached value.
Find evidence, then reduce friction
Teams look for early actions linked to later retention, then research why the link exists. People who take more steps may simply have been more motivated to begin with. The goal is to help users reach real value sooner, not just get them through more setup steps.
