Risk Management & Contingencies

Risk: Calendar API Reliability

Severity: 🟡 Medium

Mitigation: Implement retry logic, cache events locally, provide fallback to manual entry

Contingency: Build robust error handling and user notifications for sync issues

Risk: Privacy Concerns

Severity: 🔴 High

Mitigation: Role-based salary estimates, granular permissions, opt-in features

Contingency: Clear privacy policy, data deletion on request, industry benchmark option

Risk: Low User Adoption

Severity: 🔴 High

Mitigation: Pre-launch waitlist (500+), free individual version, clear value props

Contingency: A/B test messaging, expand target segments, add viral sharing features
