Matteo Technical Principles

1. Conway’s Law is paramount.

Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure.

In order to design a piece of software we need to “design” the team that is going to produce it.

2. Developer Experience is key to productivity
