Consider Conway’s Law on organizational design:

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

This rule bears non-trivial consequences.

Most notably, that changing your system architecture most often requires changing your communication structure as well — and vice versa.

For example, it is hard to organize your team into small, independent units, while retaining a monolithic structure for your software. People will likely step on each other’s toes.

Likewise, you won’t probably get the full benefits of microservices as long as your team stays a single large unit. The overhead brought on by orchestration and observability issues might not be worth it if you don’t get the upside of distributed, autonomous teams.
