plan-design-review

To identify missing design decisions in a product plan, review the document against user flows, states, validation, accessibility, and edge cases to ensure every design choice is explicit, documented, and justified with rationale.

A design-first critique for UX reviews and feature specs is a process that annotates product plans with explicit design rationales, aligns choices with product goals, and enforces traceable changes to eliminate ambiguous implementation outcomes.

Yes, you can use design rationale annotation for early-stage product plans, UX reviews, and feature spec updates to append missing design decisions, propose testable acceptance criteria, and align documented choices with user outcomes.

The best way to document design intent in a feature spec update is to append missing design decisions with concrete rationale directly to the plan, ensuring design choices are explicit, testable, and traceable within the artifacts.

Your product plan leads to ambiguous implementation outcomes when it lacks explicit design decisions and rationale, causing misaligned implementations because developers and designers do not have documented, justified design intent to follow.

You should avoid design-first critique for plan reviews if your document is purely operational or lacks user-facing states, as the process specifically targets identifying and annotating missing UX, validation, and accessibility design decisions.
