The Five Systems

One engine. Five systems. Five stages of mastery.

This is the map we work from.

The five stages · how we score every system

1
Foundational
The basics aren’t in place yet.
2
Emerging
Some pieces exist, inconsistent.
3
Working
Functional and repeatable, gaps remain.
4
Strong
Solid and mostly self-sufficient.
5
Expert
Best-in-class; it runs without us.
Stages 1–3 are the normal path, not a grade. You’ll be Expert on one system and Foundational on another. We score each system on its own, and movement up the ladder is the win.

Selling isn’t a sixth system

It’s the engine running: Target picks who, Story arms the pitch, Network gets you in the room, Pipeline moves the live deal from first call to signed, and Raise turns a proven engine into capital. Revenue is what the whole engine produces.
