Kanban Board with WIP Limits and Flow Policies

Design a complete Kanban system for:\\\\\\\\n\\\\\\\\nOrganization: [COMPANY NAME]\\\\\\\\nCurrent process: [DESCRIBE THE CURRENT WORKFLOW, E.G. BACKLOG → DESIGN → DEV → QA → DEPLOY]\\\\\\\\nTeam size: [NUMBER PER STAGE]\\\\\\\\nWeekly volume: [WORK ITEMS PER WEEK]\\\\\\\\nCurrent lead time: [DAYS]\\\\\\\\nTarget lead time: [DAYS]\\\\\\\\nMain bottleneck: [STAGE WHERE WORK ACCUMULATES]\\\\\\\\n\\\\\\\\nThe system must include:\\\\\\\\n1) Kanban board design:\\\\\\\\n   - Columns with sub-columns (Doing/Done for each stage)\\\\\\\\n   - Expedite lane for urgent items\\\\\\\\n   - Blocked lane with unblocking policy\\\\\\\\n   - Buffer between stages (when necessary)\\\\\\\\n2) WIP limits per column:\\\\\\\\n   - Calculation based on capacity (explain the formula used)\\\\\\\\n   - System-wide WIP limit\\\\\\\\n   - WIP violation rule (when it is acceptable to break the limit)\\\\\\\\n3) Explicit flow policies:\\\\\\\\n   - Entry and exit criteria for each column\\\\\\\\n   - Service classes (Standard, Fixed Date, Expedite, Intangible)\\\\\\\\n   - SLA by service class\\\\\\\\n   - Prioritization policy (FIFO, WSJF, cost of delay)\\\\\\\\n4) Meeting cadence:\\\\\\\\n   - Daily standup (format: board-focused, not person-focused)\\\\\\\\n   - Replenishment meeting (backlog refilling)\\\\\\\\n   - Delivery planning\\\\\\\\n   - Service delivery review (with CFD)\\\\\\\\n5) Flow metrics:\\\\\\\\n   - Weekly throughput\\\\\\\\n   - Lead time and cycle time (with P50, P85, P95 percentiles)\\\\\\\\n   - Cumulative Flow Diagram (CFD) — how to read and interpret\\\\\\\\n   - WIP age and blocker clustering\\\\\\\\n6) Phased implementation plan (4 weeks)\\\\\\\\n\\\\\\\\nFormat: visual board layout in text, policy tables, metrics dashboard, and rollout plan.
