+## Design Principles Applied
+
+1. **Immediate Status Visibility:** Color-coded status badges and priority indicators make task states clear at a glance
+2. **Team Ownership Clarity:** User avatars and names prominently displayed throughout interface  
+3. **3-Step Task Creation:** Simple form flow maintains user goal of ≤3 steps to create/assign task
+4. **Accessibility:** High contrast colors, clear labels, proper form structure
+5. **Responsive Design:** Desktop focuses on data density, mobile optimizes for touch interaction
+6. **Error State Guidance:** Blocked task state provides clear next actions for users
+
+## Key Assumptions
+
+- Teams of 2-15 members (confirmed by sidebar and assignee lists)
+- Desktop-first workflow with mobile support for field updates
+- Admin-managed user accounts (no self-service visible in interface)
+- Status progression: Open → In Progress → Complete (with Blocked as exception state)
+- Priority and due dates are essential task attributes for small team coordination
