Risk Buffer Guide
When to use each buffer level.
Low (10%)
Stable team, well-defined scope, familiar tech
Medium (25%)
Normal projects, some unknowns expected
High (50%)
New tech, complex integrations, external dependencies
Very High (100%)
R&D, new team, vague requirements
Project Estimation Tips
Accurate estimates require realistic velocity data and appropriate risk buffers.
Best Practices
- Use historical velocity — Average of last 3-5 sprints
- Add buffer for unknowns — 25-50% is reasonable
- Account for meetings — Real coding time is less than you think
- Plan for holidays — Check your calendar for time off
Common Estimation Mistakes
- Using ideal velocity instead of actual
- Not accounting for code review and testing
- Ignoring external dependencies
- Underestimating integration complexity
