What is right size for Epic, Story, Task, Sub-task ?

Tridip Charukia

Hi Team, 

I have 2 queries if someone can help.

1. What is right size we should keep for each type of issue in JIRA?

For Example,

Max 10-20 Story points in each Story (1 Story Point = 1 day of work)

Max 20 Hrs for any Sub-task (Measuring Sub-task by Hrs)

 

2. What is the best way to decide to choose between Story and Task ?  

 

Thanks

It's whatever size your team works with best.

Story points are not a measure of time though, please don't do that.  They are a relative sizing between issues, and have no link to time - your teams will regularly do things like logging 1 hour on an 8 point story and 12 hours on a 2 point story.  If you want to estimate in hours instead of relative sizing, either use the original estimate as the estimate, or create a numeric hour field.

The other two things you need to look at are:

• The estimate for a story should be smaller than the size of the sprint - the whole point of a sprint is that you complete entire stories, so if a story is too big to do in one sprint, it needs to be split up into several stories (and maybe those contained within an Epic.
• Sprint estimates do not go on to sub-tasks.  Sub-tasks are fragments of their parent, not sprint items.
