- Phase 3 - Recommendations & Roadmap (Weeks 5-8)
The consultant will provide a realistic roadmap that balances security, stability, cost, and staffing.

- Prioritized Recommendations Matrix (by risk reduction, cost, complexity, effort)
- 12-24 Month Network Roadmap including sequencing and dependencies
- Modernization guidance (architecture direction, lifecycle replacement, monitoring improvements)
- Budgetary ROM estimates where possible (not formal quotes)
- Leadership Readout (slide deck or summary presentation)
Phase 4 - Optional Ongoing Support (Month 2+ as needed)
Based on findings and City priorities, the consultant may continue in a part-time or expanded role to execute improvements, provide operational continuity, support vendor engagements, and help transition to permanent staffing.
