If the advantage of story points is just to make sure how much story points of work we can take up in a sprint and nothing more than that then instead of story points can we simply assign hours to story ?
For example - Story A has 3 tasks
Task A - 3 hours
Task B- 2 hours
Task C- 6 hours
So we can assign 11 hours to story A. This is our best guess obviously .
Over the period of time, we will get to know how many hours we as a team can complete on an average.
I would like to know any flip side of this approach.
