UI Quality & Craft

Visual and interaction quality of shipped interfaces. Fidelity to design intent. Polish in edge cases.

Exceeds

Shipped UI is indistinguishable from design intent. Edge cases are handled with the same care as happy paths.

Meets

UI matches design spec with minor variations. Edge cases are handled adequately.

Below

Shipped UI diverges from design intent in noticeable ways. Edge cases are often broken or unstyled.

Example review phrases

  • "Designers consistently say their implementations are the most faithful in the org—pixel-perfect and interaction-precise."
  • "Redesign shipped with full responsive coverage across 5 breakpoints with zero visual regression QA issues."

Web Performance

Core Web Vitals, bundle size management, and performance optimization for real users.

Exceeds

Core Web Vitals are in the green across all pages they own. Proactively identifies and reduces bundle bloat.

Meets

Core Web Vitals are acceptable. Aware of bundle impact. Performance is not a consistent concern.

Below

Performance regressions are introduced without awareness. Bundle size grows unchecked.

Example review phrases

  • "LCP on the landing page improved from 4.1s to 1.8s after their optimization work—conversion improved 12%."
  • "Audited and reduced main bundle size by 38% without functional regression."

Design-Engineering Collaboration

Partnership quality with designers. Ability to give feedback on feasibility and translate designs into engineering constraints.

Exceeds

Designers seek their feedback before finalizing specs. Proactively surfaces technical constraints early so designs are shippable.

Meets

Works well with designers. Flags major feasibility issues before starting implementation.

Below

Design-to-implementation gaps are discovered late. Rarely engaged in design reviews.

Example review phrases

  • "Designer's note: They are the first engineer who ever pushed back on an animation spec and proposed a better alternative—and they were right."

Where do these examples come from in real reviews?

Most managers write performance reviews from memory—limited to what they personally observed. Confirm surfaces behavioral evidence from across the organization: who relied on this person, what they drove, how their impact extended beyond their direct manager's line of sight. Reviews written with Confirm's data are more accurate, more defensible, and faster to write.
