The review behind the score

The score becomes useful when the removed context is written back beside it.

Table 1The review behind the score

Score component	Name the boundary	Read the movement	Ask before acting
Growth	Starting cohort, currency, acquisitions and price changes	New demand, expansion, mix or timing	What remains if acquisition spend stops?
Margin	Gross, operating or cash measure and included costs	Price, mix, delivery cost or deferred investment	Which future capability was not funded?
Time	Measurement window and comparison period	Acceleration, deceleration or one-off base effect	Does the mechanism persist after the period?
Stock	What survives and who maintains it	New asset, maintained asset or no durable output	Can the next team use it without rebuilding it?

From the essay

Growth that compounds

The Rule of 40 is a trade-off, not a target

The Rule of 40 compresses growth and margin into one score. Use it to expose a trade-off and its timing, not to reward a team for crossing a line.
