I used Jira to work as follow:
My question is related to the connection I made with Story, Task, and sub-task.
A story is a Sprint container of one or more tasks.
Each Task should be defined by the PM such as Feature Design, Feature Implementation, Feature, Research...
Sub-Tasks are the development breakdown to small pieces and are created and maintained by the developers. Sub-tasks own worklog and effort estimation
1) I do see the Sub Tasks Time spent is calculated on the Task level but I do not see that aggregate to the Story.
2) Maybe there is a different approach to do it?
Thanks a lot.
