Risk Mitigation

Technical Risks

• OSBuild Complexity: Start with simple modifications, build complexity gradually
• Integration Challenges: Use well-defined interfaces, test integration points early
• Performance Issues: Test performance early, optimize continuously
• Compatibility Issues: Test with real Debian packages, validate edge cases

Timeline Risks

• Scope Creep: Stick to core functionality, defer advanced features
• Integration Delays: Plan integration carefully, test early and often
• Testing Complexity: Start testing early, automate testing where possible
• Documentation: Document as you go, don't leave it until the end

Resource Risks

• Developer Availability: Plan for developer rotation, document everything
• Infrastructure Issues: Use simple infrastructure initially, scale gradually
• Dependency Changes: Monitor upstream projects, plan for changes

Notes

• Priority: Focus on core functionality first, add advanced features later
• Testing: Test each component individually before integration
• Documentation: Document everything as you go, don't assume you'll remember
• Iteration: Use iterative development, get working system early and improve gradually
• Community: Engage with Debian community early for feedback and adoption
