Key Design Decisions

1. Story Detail Page Layout

Decision: Two-column layout with main content + metadata sidebar

Rationale:

• Consistent with Epic detail page design
• Separates core content from metadata
• Optimizes for 80% use case (reading details)

Layout:

┌────────────────────────────────────────────────┐
│ [Breadcrumb] [←] Story Title    [Edit][Delete] │
├────────────────────────────────────────────────┤
│ ┌─────────────────────┐  ┌──────────────────┐ │
│ │ Story Details       │  │ Metadata Sidebar │ │
│ │ - Description       │  │ - Status         │ │
│ │ - Acceptance Criteria│  │ - Priority      │ │
│ │ - Tasks (8)         │  │ - Assignee       │ │
│ │ - Activity Timeline │  │ - Parent Epic    │ │
│ └─────────────────────┘  └──────────────────┘ │
└────────────────────────────────────────────────┘

2. Story Creation Flow

Decision: Hybrid approach (Quick Add + Full Form)

Quick Add (Inline):

• For rapid Story creation
• Title + Priority only
• Inline form at top of Stories section
• Keyboard shortcut: Cmd/Ctrl + N

Full Form (Dialog):

• For detailed Stories
• All fields available (description, assignee, acceptance criteria)
• Accessed via [+ New Story] button

Rationale:

• Supports both quick workflows and detailed planning
• Reduces clicks for common case (simple Story)
• Maintains consistency with Epic creation pattern

3. Kanban Board Enhancements

Decision: Add contextual Story creation from Epic cards

New Interaction:

Hover over Epic card → [+ Add Story] button appears
Click → Inline Story form opens below Epic card
Create → Story appears in correct Kanban column

Rationale:

• Reduces navigation (no need to open Epic detail)
• Maintains context (Epic visible while creating)
• Faster workflow for batch Story creation

4. Task Management in Story Detail

Decision: Expandable Task list with inline creation

Features:

• Checkbox for quick status toggle
• Filters: Status, Priority, Assignee
• Sort: Priority, Status, Date, Assignee
• Drag to reorder
• Inline Quick Add Task

Rationale:

• Tasks are critical to Story completion
• Users need quick Task updates without navigation
• Aligns with "Flow" principle (minimize steps)

5. Activity Timeline

Decision: Show full change history with filtering

Display:

• Icon-based event types (status, assignment, comment)
• Relative timestamps ("2h ago")
• Filters: All, Changes, Comments, Assignments
• Infinite scroll / Load More

Rationale:

• Transparency: Users see all changes
• Collaboration: Track team activity
• Audit trail: Compliance requirement

Risk & Mitigation

Risk 1: Complex Task Management

Issue: Task list with filters, sorting, drag-drop is complex

Mitigation:

• Start with basic Task list (Phase 1)
• Add features incrementally (Phase 3)
• Use proven library (@dnd-kit) for drag-drop
• Extensive testing with real users

Risk 2: Real-time Update Conflicts

Issue: Multiple users editing same Story simultaneously

Mitigation:

• Optimistic UI updates with revert on conflict
• SignalR broadcasts changes to all users
• Show "Someone else is editing" indicator
• Auto-refresh on conflict detection

Risk 3: Mobile UX Complexity

Issue: Story detail page has many sections for small screens

Mitigation:

• Use tabs on mobile (Details | Tasks | Activity)
• Bottom sheets for forms (not full dialogs)
• Progressive disclosure (collapse sections)
• Swipe gestures for common actions

Risk 4: Performance with Large Task Lists

Issue: Stories with 50+ Tasks may be slow

Mitigation:

• Virtual scrolling for Task lists (react-window)
• Pagination or "Load More" for Activity Timeline
• Optimize SignalR payload size
• Backend pagination for Tasks API

Design Review Checklist

Before implementation, verify:

• Layout matches existing Epic page consistency
• All interactive elements have hover/focus states
• Color contrast passes WCAG AA (4.5:1)
• Keyboard shortcuts don't conflict with browser
• Mobile design provides equivalent functionality
• Loading states defined for all async operations
• Error messages are user-friendly and actionable
• ARIA labels added to all interactive elements
• Design tokens match ColaFlow design system
• User flows tested with real scenarios

Questions for Product Team

1. Acceptance Criteria: Should this be a simple checkbox list or rich text?
2. Story Status Transitions: Are all transitions allowed (e.g., Done → Backlog)?
3. Task Limits: Is there a maximum number of Tasks per Story?
4. Batch Operations: Priority for bulk Story creation/update?
5. Integrations: Will Stories sync with external tools (GitHub, Jira)?
6. AI Features: Should AI suggest Story breakdown or acceptance criteria?

---

Next Steps

1. Design Review: Schedule with Product, Engineering, QA teams
2. Prototype: Create Figma interactive prototype (optional)
3. User Testing: Test flows with Lisa (PM) and David (Dev) personas
4. Implementation: Start Phase 1 (Core Story Detail)
5. Iteration: Gather feedback after each phase, adjust design
