In this episode of "Stories of Software Architecture and Design," hosts Kenny (Baas) Schwegler and Andrea Magnorsky welcome back guests Elena and Pete to discuss the challenges of managing team autonomy when an architect disagrees with a decision.

Pete, who discussed this topic at QCon, shares his perspective on dealing with decisions made by teams that he felt were incorrect.

1. Architect's Dilemma and Self-Reflection: Pete shared his challenge when teams made decisions he disagreed with, stressing the need for the architect to first reflect on whether their own feedback was persuasive and to remove emotional attachment from the outcome.
2. Building Accountability and Skills: The discussion covered the difficulty when teams lack the "harder skills" for questioning , emphasizing that Architecture Principles are key for guidance, especially regarding cost , and that the architects' role is critical for supporting teams to build accountability and trust.
3. Decisions Across Boundaries: The team tackled the issue of decisions affecting multiple teams (i.e., "context wars") , confirming that a key tool is the Context Map (from DDD) to promote autonomy and that dealing with this requires facilitating communication.
4. Granularity of ADRs: A challenge was the differing frequency and size of Architecture Decision Records (ADRs) across teams. The consensus was to encourage teams to write ADRs, even small ones that don't need the formal advice forum , as long as they find their right flow and document impactful decisions.
