architectural-proposals

An architectural proposal aligns teams by documenting problem statements, proposed architecture, changes, risks, and decisions with explicit trade-offs and sign-offs. Creating this documentation before coding makes it cheaper to change a doc than refactor code.

You need an architecture proposal when architecture shifts invalidate existing assumptions, product direction changes require new foundations, multiple waves are affected, or external dependencies change. Early alignment prevents costly refactoring across affected milestones.

Document risks in architecture proposals by capturing risk statements with likelihood, impact, and concrete mitigation steps to reduce uncertainties. Frame decisions by presenting recommendations alongside alternatives, rationale, and required sign-offs to accelerate team alignment.

Use a wave restructuring pattern that clearly reframes waves and updates dependencies to preserve parallel work where possible. Document this in your proposal to maintain alignment across affected teams and milestones.

Accelerate team sign-offs on architecture changes by using explicit decision framing that presents a recommendation with alternatives, rationale, and required sign-offs. Including evidence, risks with mitigations, and examples of common mistakes guides consistent proposals and faster agreement.
