+## Project Information
+
+| Field | Value |
+|---|---|
+| Project Name | |
+| Organization | |
+| Project Lead | |
+| Start Date | |
+| Segmentation Tool | [Illumio / VMware NSX / Guardicore / Cisco ACI] |
+
+## Workload Inventory
+
+| Workload | IP Address | OS | Role | Application | Environment | Location |
+|---|---|---|---|---|---|---|
+| | | | web | | prod | |
+| | | | app | | prod | |
+| | | | db | | prod | |
+
+## Segmentation Zone Design
+
+### Zone Definitions
+
+| Zone Name | Description | Workloads | Default Policy |
+|---|---|---|---|
+| PCI-CDE | Cardholder data environment | [list] | Deny-all |
+| HR-Systems | HR applications | [list] | Deny-all |
+| DMZ | Internet-facing services | [list] | Deny-all |
+| Management | Admin/monitoring | [list] | Restricted |
+
+### Inter-Zone Communication Matrix
+
+| Source Zone | Destination Zone | Ports/Protocols | Justification |
+|---|---|---|---|
+| DMZ | App-Tier | 8080/tcp | Web application traffic |
+| App-Tier | DB-Tier | 3306/tcp | Database queries |
+| Management | All Zones | 22/tcp, 9090/tcp | SSH and monitoring |
+
+## Policy Rules
+
+### Allow Rules
+
+| Rule ID | Source | Destination | Port | Protocol | Process | Justification |
+|---|---|---|---|---|---|---|
+| 1 | | | | tcp | | |
+| 2 | | | | tcp | | |
+
+### Default Deny
+- All traffic not explicitly allowed is denied
+- Deny rule logged and alerted
+
+## Enforcement Schedule
+
+| Week | Activity | Applications | Risk Level |
+|---|---|---|---|
+| 1-2 | Agent deployment and discovery | All | Low |
+| 3-4 | Label assignment and validation | All | Low |
+| 5-6 | Policy design and test mode | All | Low |
+| 7 | Enforce: Dev/Test environments | Dev apps | Low |
+| 8 | Enforce: Low-risk production | Non-critical | Medium |
+| 9-10 | Enforce: Business-critical apps | ERP, CRM | High |
+| 11-12 | Enforce: Regulated environments | PCI, HIPAA | High |
+
+## Validation Tests
+
+- [ ] Legitimate traffic flows uninterrupted after enforcement
+- [ ] Unauthorized cross-zone traffic is blocked
+- [ ] Lateral movement from compromised workload is contained
+- [ ] Policy violation alerts appear in SIEM
+- [ ] Break-glass procedure works for emergency access
+- [ ] Application dependency map matches actual flows
