How much of what you build
actually reaches your customer?

Three inputs. One diagnosis. See your health, your engine efficiency, and what friction is costing you in time.

Step 1
Where are you in the cycle?
Sets the healthy benchmark. The same score means different things at different phases.
Step 2
How good is your engine?
Product-market fit. Team capability. The raw quality of what you produce before friction touches it.
Engine quality M0.70
Weakmin 0.38peak 0.67Max
Step 3
How much friction?
Everything that absorbs output before it reaches your customer. Structural minimum is 0.236 — you cannot go below this.
Total friction D0.30
Nonemin 0.24danger 0.50critical
People past their phase0.05
Wrong people in wrong phase. Founders still building in Conservation.
Process mass0.03
Processes managing processes. Meetings about meetings.
Observer confusion0.00
Cascades to every agent. The most dangerous friction source.
Step 4 — optional
How fast do you cycle?
Calculates what friction costs you in time.
Product cycle6 wks
One build-ship-learn loop.
Cycles completed4
How many full loops done so far.
