Kanban Principles
Core Practices
- Visualize the workflow - Make work visible
- Limit WIP - Focus on finishing, not starting
- Manage flow - Optimize throughput
- Make policies explicit - Clear rules for moving work
- Implement feedback loops - Regular reviews
- Improve collaboratively - Continuous improvement
WIP Limits
```markdown
WIP Limit Guidelines
| Column | WIP Limit | Rationale |
|---|---|---|
| Backlog | ∞ | Unlimited ideas storage |
| To Do | 10 | Committed work for near-term |
| In Progress | 5 | Active development capacity |
| Review | 3 | Prevent review bottleneck |
| Done | ∞ | Completed work archive |
Setting WIP Limits
- Start with team size × 1.5
- Adjust based on flow metrics
- Too high = loss of focus
- Too low = idle time ```
Flow Metrics
Lead Time vs Cycle Time
``` Lead Time ◄───────────────────────────────────────────► │ │ │ Cycle Time │ │ ◄─────────────────────► │ │ │ │ │ ┌───▼────▼───┐ ┌──────────┐ ┌──────────┐ ┌▼─────────┐ │ Created │──►│In Progress│──►│ Review │──►│ Done │ │ (Backlog) │ │ │ │ │ │ │ └────────────┘ └──────────┘ └──────────┘ └──────────┘
Lead Time: Time from request to delivery Cycle Time: Time from start to completion ```
Throughput Calculation
```python
Throughput: Items completed per time period
def calculate_throughput(completed_items: list, period_days: int) -> float: items_completed = len(completed_items) throughput = items_completed / period_days return throughput
Example
completed_this_week = 15 throughput = completed_this_week / 7 # 2.14 items per day ```

Card Structure
```markdown
Kanban Card Template
Title
[Clear, concise description]
Type
[ ] Feature [ ] Bug [ ] Tech Debt [ ] Support
Details
- Requester: [Name]
- Priority: [High/Medium/Low]
- Size: [S/M/L/XL]
- Due Date: [If applicable]
Description
[What needs to be done]
Acceptance Criteria
- Criterion 1
- Criterion 2
Blockers
[Any dependencies or impediments]
Class of Service
[ ] Expedite (Urgent, bypass WIP) [ ] Fixed Date (External deadline) [ ] Standard (Normal flow) [ ] Intangible (Low priority) ```
Service Level Expectations
```markdown
SLE by Card Type
| Type | Target Lead Time | % On Time Target |
|---|---|---|
| Expedite | 1 day | 95% |
| Bug Fix | 3 days | 90% |
| Feature | 2 weeks | 85% |
| Tech Debt | 1 month | 80% |
| ``` |

Kanban Meetings
Daily Standup (Walking the Board)
- Start from right (Done) to left (Backlog)
- Focus on blocked items
- Identify bottlenecks
- 15 minutes max
Replenishment Meeting (Weekly)
- Review backlog
- Prioritize incoming work
- Pull items to "To Do"
- Discuss capacity
Delivery Planning (Bi-weekly)
- Review completed items
- Update forecasts
- Communicate delivery dates
Golden Armada Kanban Commands
```bash
View board status
/kanban-status --board golden-armada
Add item to backlog
/kanban-add --title "Feature X" --type feature --size M
Move item
/kanban-move GA-123 --to "In Progress"
Generate metrics report
/kanban-metrics --period 30d ```
