Nice to see big companies working like this. I wish more places would understand that different approaches work for different people, teams, products, technologies and contexts. There is no one true way, and most attempts to impose one tend to create something that is bigger and more complex than any single team needs. It's like the human equivalent of a code library that is trying to solve too many problems and so becomes an unweildy mess of config and options and meta-problems.

We (Bugsnag) are a relatively small engineering team, so have the advantage of low comms overhead, and we do have an overarching approach, but each of the teams works a bit differently. Even from project to project I'll adjust what makes sense based on complexity/risk/size.
