One simple way of hermetically sealing organizational complexity: microservices.
Many people don't seem to understand when to use microservices. They're not for small teams.
I believe the real benefit of them is that you can have a team at say, Amazon, who works on their product prediction engine. They have well defined input data, and they have well defined data consumers need as an output. Beyond that, they just have to coordinate within their own team to build what they need to.
They don't have to meet with stakeholders across the organization and get into debates with ten other guys in other departments about adding a database field. They have their own database, of their own design, and they do with it what they want. If they need more data they query some other microservice.
