Individual interventions in the system do not help

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.

Big Batches™ and assumptions

  • way more second-order, compounded assumptions as a product of first order-assumptions (A x B x C x … x N)
  • carry all of these for a longer time

It’s not about:

  • Continuous Integration

What is a high transaction cost?

An example is of transaction cost is how long it takes us to get enough confidence that our change didn’t break previous functionality.

In most cases a big batch is

an indication of a lack of mechanism to reduce the transaction cost.

Two intervention points for the fastest flow

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.
