Estimating stories faster and more accurately

In a recently endeavour to find the blogs of all Agile Manifesto’s authors, I’ve found this post of James Grenning about some planning poker companion games. Luckily, we were about to do a release planning for both Brasigo and BlogBlogs here at WebCo, just the perfect opportunities to try a new approach to estimating.

The results:

  • 20 stories estimated in just one hour!
  • much more coherent estimation!
  • much more accurate estimation!

Why?

  • faster due to the great amount of example stories per column of similar difficult, facilitating the comprehension of everybody;
  • coherent, because the team compared almost all stories against each other to correctly sort them in columns of similar difficult;
  • accurate, also due to the great amount of example stories per column of similar difficult, so that each column had much more information than a single story could give in an usual planning poker game;

Conclusion

I highly recommend this method! Not only for release plannings, but for all estimation sessions. It is deep enough to do always.

    Tiago,

    muito obrigado pela dica, realmente o time conseguiu estimar 22 histórias em 45′. O resultado foi muito satisfatório, pois o time se sentiu muito seguro, conseguiu estimar com mais precisão em relação às outras histórias e a proporcionalidade entre os números ficou mais clara.

    []s,
