Technical Evaluation Framework: Vetting Web Application Design Partners

Web application design requires deep systems thinking that goes far beyond marketing aesthetics. Enterprise SaaS tools, customer portals, and internal dashboards require intuitive workflows, rigorous state management, and scalable design tokens that integrate seamlessly with frontend codebases (React, Vue, Angular).

1. Critical SaaS & Web App UX Capabilities

• ▸
  State Machine UX Design: Comprehensive interface design for every user state: default data, active loading (skeleton screens), empty zero-states with onboarding CTAs, input error validation, and partial failure states.
• ▸
  Data Density & Complex Table Ergonomics: Resizable columns, sticky headers, bulk action toolbars, faceted multi-select filters, inline editing, and responsive mobile card fallbacks for enterprise tabular data.
• ▸
  Atomic Design Systems & Token Architecture: Organized component hierarchy (Atoms, Molecules, Organisms, Templates) utilizing Figma Variables for typography scales, spacing grids, theme switching (dark/light mode), and semantic color tokens.
• ▸
  Developer Handoff Hygiene: Production-ready Figma structures with explicit Auto Layout rules, component properties, variant states, and interactive prototype specs ready for frontend engineering.

2. Vetting Questions for Engineering & Product Leaders

1. ▸
   "Can we review a real-world Figma file from your portfolio to inspect your Auto Layout conventions, component naming, and token architecture?"
2. ▸
   "How do you test and validate workflows for complex permissions (multi-tenant RBAC, read-only vs admin roles)?"
3. ▸
   "Do you conduct usability testing with actual target users using interactive prototypes before finalized sign-off?"
4. ▸
   "Have your designers worked directly inside Storybook, Tailwind configuration, or Git pull requests alongside engineering teams?"

3. Red Flags

• ▸
  Dribbble-Style 'Unbuildable' UIs: Concepts featuring micro-fonts, zero contrast, or floating elements that look futuristic in a snapshot but collapse under real data and edge cases.
• ▸
  Ignoring Keyboard Navigation & Shortcuts: Dashboards designed strictly for mouse clicks without tab order, focus rings, or power-user hotkeys.
• ▸
  Missing Loading & Error Specs: Handing over only "happy path" static screens and leaving frontend developers to invent edge-case UX during sprints.
