How to do Agile estimation with story points? Agile estimation is based on simple principles:
- apply relative comparison as people are better in relative estimation not absolute,
- compare items with estimation references included in the estimation catalogue,
- use a simple scale based on the modified Fibonacci scale numbers of which are known as the storypoint,
- estimate together, as a crowd,
- agree on final estimation,
- compare the complexity of problems, not the time necessary for its implementation as it can differ by team members,
- don’t over-invest the time into the estimation,
- don’t dive into deep details,
- accuracy is more important than precision,
- don’t estimate all items, just a few of them which will be implemented in the next sprint, or program/product increment time period.
