Andrew Harmel-Law:

The moves in software delivery towards ever-increasing team autonomy have, in my mind at least, heightened the need for more architectural thinking combined with alternative approaches to architectural Decision Making.

Ensuring our software teams experience true autonomy raises a key problem: how might a small group of architects feed a significant number of hungry, value-stream-aligned teams? Why? Because in this environment Architects now need to be in many, many more places at once, doing all that traditional “architecture”.

…

The Rule: anyone can make an architectural decision.

The Qualifier: before making the decision, the decision-taker must consult two groups: The first is everyone who will be meaningfully affected by the decision. The second is people with expertise in the area the decision is being taken.
