Architecture Decision Documentation and Communication Questions

Covers the practices for capturing, organizing, and communicating architectural decisions and the rationale behind them. Candidates should be able to describe how to create architecture decision records and design documents, record alternatives considered, list pros and cons, and show impacts on scalability, cost, maintainability, security, and operations. This topic also covers techniques for communicating decisions to engineers, product managers, and non technical stakeholders, obtaining buy in, handling feedback and dissent, and evolving documentation as requirements change. Interviewers may probe how candidates link decisions to requirements, trace implications across components, and ensure decisions are discoverable and revisited when assumptions change.
