Success metrics must be defined before execution.

🚩 Failure to Report

The Violation
The Principle

Teams cannot clearly define what success looks like.

The call

Defining what success looks like after a campaign launches means you're measuring backward. Pre-defined KPIs create accountability, enable optimization, and prevent gut-feel from passing as analysis.

The Legends

Hopkins: "Treat it as a salesman. Force it to justify itself. Compare it with other salesmen. Figure its cost and result. Accept no excuses which good salesmen do not make."

In Action (the tape)

• “It feels like it’s working”

Owned — Teams don’t know success metrics.

Earned — PR success measured subjectively.

Paid — Spend tracked without ROI.

Analytics — KPIs defined after launch.

AI — AI outputs evaluated emotionally, not empirically.
