Im trying to understand whether a project could be done in twelve weeks of development effortand whether my team will have control in the project to realistically manage towards that goal. Want to take 7pace for a spin? Story points vs. hours 9. Creating such a forecast involves a substantial upfront investment in both time and money, but it pays off through a better product that satisfies its customers needs.

Prioritize tasks and features 5. However, creating one isnt an easy task. The X axis corresponds to the estimation, and the Y axis to the probability, that this estimation will be true, and the task will last for a certain period of time (neither more, nor less). After estimating software development time, we found out that the development required 2.5 months with next support on a 10-hours-per-week basis. amazing content and it was very helpful and very well explained.
