Systems with high transaction cost will always revert back to big batches no matter how much we try to encourage individual actors to reduce the size of the batch.
Actors act rationally within a given set of constraints imposed by the system, so the intervention point must be at the system level, not on the individual level.
I cannot have a fast feedback if I don’t have small batches.
But, I could have a slow feedback even if I have small batches.
That’s the case when WIP is too high, which causes queueing in the system, which then delays the feedback.
