2. Budget Risk Mitigation

Change Control Board: Review all scope changes
Monthly Budget Reviews: Track burn rate
Vendor Negotiations: Lock in rates early
Resource Flexibility: Mix of FTE and contractors

3. User Adoption Risk Mitigation

Beta Program: 50 teachers, 500 students
Training Materials: Videos, guides, webinars
Feedback Loops: Weekly surveys during beta
Champion Program: Early adopter incentives

Code Reviews: Mandatory for all changes
Automated Testing: 80% code coverage target
Performance Budgets: Set and monitor limits
Technical Spikes: Research before implementation

Contingency Plans

Scenario 1: 4-Week Delay

Reduce scope to P0 features only
Increase team size for critical path items
Consider November 1 beta launch

Scenario 2: 20% Budget Overrun

Defer P1 features to Phase 2
Negotiate payment terms with vendors
Seek additional funding approval
