Herbig's test for a strategy line is right: if the opposite is stupid, it was never a choice. His test for whether the whole strategy is working is the one I would replace, because mine passed it for an entire spring in which the strategy refused nothing and 13 of 39 builds ended up as orphans.
The ledger format, the flip applied to the two lines most AI strategy decks open with, and why three writers landed on the same point in one week are in A Strategy Is Working When It Said No This Week. Count the Nos.. The loop that fills the ledger is One Problem a Week, and the 39 builds are counted in Twenty Minutes Is Not a Reason to Build.
