如何计算Story Point Estimate
learn.whatIsHeading
Assigns effort size to work items using relative estimation. Enables velocity tracking and capacity planning independent of time.
分步指南
- 1Select reference story of known size
- 2Compare other stories to reference
- 3Assign Fibonacci points (1, 2, 3, 5, 8, 13...)
- 4Use relative difficulty, not absolute time
- 5Refine estimates after completion

常见问题
Are story points hours?
No; points measure relative complexity, not time; same 5-point story might take 4-8 hours.
How accurate should estimates be?
Typically ±50% acceptable; consistency matters more than precision.
