The waterfall mental model is the most common installation failure. A team finishes Scan, finishes Story, finishes Stake, and then declares the cycle done. What they have done is build a quarterly planning ritual with new vocabulary. The discipline never closes the loop because the operating environment never stops moving.
In practice, the four phases overlap. The Signal Steward is already feeding Wednesday's intake into next month's Story read while last quarter's Stake is still being steered. The diagram looks like four points on a circle for the same reason a clock face does — they are all true at once. Position on the circle is a function of cadence, not phase completion.
The accent arc on the diagram — Steer returning to Scan — is where the discipline pays for itself. Every Steer cycle re-seeds the next Scan with what the world actually did, which indicators triggered, which scenarios collapsed. The fifth revolution of the loop is not the same loop running again. It is a sharper instrument with a memory.
The person who runs the Loop on behalf of the leadership team is the Predictionist.
