Full UX audit checklist with severity scoring

# UX Audit Report: TaskFlow (Project Management App) ## Executive Summary This audit evaluated TaskFlow against Nielsen's 10 usability heuristics across 14 key screens and 8 primary user flows. We identified **23 usability issues**: 3 critical (severity 4), 5 major (severity 3), 9 moderate (severity 2), and 6 minor (severity 1). The most urgent issues involve inconsistent navigation patterns, missing system feedback during bulk operations, and poor error recovery in the project creation flow. **Overall Usability Score: 62/100** — Below industry benchmark of 72 for B2B SaaS tools. --- ## Prioritized Findings ### H1: Visibility of System Status | # | Issue | Severity | Screen | Fix | Effort | |---|-------|----------|--------|-----|--------| | 1.1 | No progress indicator during file uploads — users click "Upload" repeatedly, creating duplicates | 4 | Task Detail | Add upload progress bar with cancel button, disable submit during upload | Low | | 1.2 | Bulk task deletion shows no confirmation or progress — 50+ tasks silently delete | 4 | Board View | Add confirmation modal with count, progress indicator, and undo window (30s) | Medium | | 1.3 | Save status unclear in Settings — no "saved" confirmation after changing preferences | 2 | Settings | Add auto-save toast notification with "Settings saved" confirmation | Low | ### H2: Match Between System and Real World | # | Issue | Severity | Screen | Fix | Effort | |---|-------|----------|--------|-----|--------| | 2.1 | "Sprint velocity" shown to non-technical stakeholders without explanation | 3 | Dashboard | Add tooltip definitions, offer "simple view" toggle that uses plain language | Low | | 2.2 | Date picker uses MM/DD/YYYY format for international users | 2 | Task Creation | Detect locale, use locale-appropriate format, add format hint text | Medium | ### H3: User Control and Freedom | # | Issue | Severity | Screen | Fix | Effort | |---|-------|----------|--------|-----|--------| | 3.1 | No undo for task status changes — accidental drag-and-drop on Kanban board is permanent | 4 | Board View | Implement undo stack with Ctrl+Z support and toast with "Undo" action button | High | | 3.2 | Cannot exit project creation wizard mid-flow without losing all input | 3 | Project Wizard | Auto-save draft state to localStorage, add "Save as Draft" button | Medium | ### H4: Consistency and Standards | # | Issue | Severity | Screen | Fix | Effort | |---|-------|----------|--------|-----|--------| | 4.1 | Primary action button is blue on some pages, green on others | 2 | Global | Standardize to single primary color in design tokens | Low | | 4.2 | "Close" means "archive" in Projects but "dismiss" in Notifications | 3 | Projects, Notifications | Rename to "Archive Project" and "Dismiss" respectively | Low | ### H5: Error Prevention | # | Issue | Severity | Screen | Fix | Effort | |---|-------|----------|--------|-----|--------| | 5.1 | Can assign task to team member who left the project | 2 | Task Edit | Filter assignee dropdown to active project members only | Low | | 5.2 | Due date can be set before start date without warning | 2 | Task Creation | Add date validation, disable invalid date ranges in picker | Low | ### H6: Recognition Rather Than Recall | # | Issue | Severity | Screen | Fix | Effort | |---|-------|----------|--------|-----|--------| | 6.1 | Recently viewed projects not shown — users must search every time | 3 | Dashboard | Add "Recent Projects" section with last 5 visited projects | Low | | 6.2 | Filter settings reset on page navigation — users re-apply filters repeatedly | 3 | Board View | Persist filter state in URL params and localStorage | Medium | ### H7: Flexibility and Efficiency of Use | # | Issue | Severity | Screen | Fix | Effort | |---|-------|----------|--------|-----|--------| | 7.1 | No keyboard shortcuts for power users — all actions require mouse | 2 | Global | Add keyboard shortcut system (? to show cheat sheet) | High | | 7.2 | Cannot create task from any screen — must navigate to specific project first | 2 | Global | Add global "Quick Add" shortcut (Cmd+K) with project selector | Medium | ### H8-10: Additional Findings | # | Heuristic | Issue | Severity | Fix | Effort | |---|-----------|-------|----------|-----|--------| | 8.1 | Aesthetic/Minimalist | Dashboard shows 12 widgets by default — information overload | 2 | Default to 4 essential widgets, let users customize | Medium | | 9.1 | Error Recovery | API errors show raw "500 Internal Server Error" | 3 | Map error codes to friendly messages with suggested actions | Medium | | 9.2 | Error Recovery | Form validation only triggers on submit — no inline feedback | 1 | Add real-time inline validation on blur | Medium | | 10.1 | Help/Docs | No onboarding tour for first-time users — 68% day-1 drop-off | 3 | Add 5-step guided tour, triggered on first login | Medium | | 10.2 | Help/Docs | Help center opens with no context — users search from scratch | 1 | Add contextual help icons that deep-link to relevant docs | Low | --- ## Fix Roadmap (Prioritized by Impact/Effort) ### Sprint 1 — Quick Wins (Low effort, High impact) 1.
