I just came to a realization that #mobprogramming is (also) an implementation of “stop the line” a.k.a. “andon cord” concept from Lean…

Do you know that code reviews with Pair/Mob Programming are virtually free?

An abundance of those is what builds the quality in.
Not a staged and expensive, khm Pull Requests khm, process.

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

  • more assumptions
  • way more second-order, compounded assumptions as a product of first order-assumptions (A x B x C x … x N)

It's actually not about practices

It’s not about:

  • Continuous Integration
  • Trunk Based Development
  • Pair Programming
  • Mob Programming
  • Limiting WIP
