"Each team is full-stack and full-lifecycle: responsible for front-end, back-end, database, business analysis, feature prioritization, UX, testing, deployment, monitoring"

"But they also shouldn't be too large, ideally each one is a Two Pizza Team"

Either that's a team with some hugely diversified skills, or that's two car-sized pizzas

I'm a simple man, I see Fowler and I upvote

But then I read this article and it is very thin puff piece for the book. Very little insight

Obey conways law, you can't break it

I like the concept of reducing cognitive load for the stream-aligned teams. This means all efforts go towards enabling them as much as possible in supporting the business. It also makes it relatively easy to judge if a platform team is doing the right things.

Conway's Law is a category-theoretic statement; it asserts the existence of a homomorphism on graphs, mapping from modules to code authors. Quoting Conway's original paper:

Speaking as a mathematician might, we would say that there is a homomorphism from the linear graph of a system to the linear graph of its design organization.

The author does not really show an understanding or respect for the underlying maths.
