Hi. First of all i am not a newbie in Jira.. But i couldn't find anything that can give me this simple requirement that we need in order to have simple workflow.
Our current workflow is that:

Open -> Dev in progress -> Dev done - >Pending QA -> QA in Progress -> QA Done
We need really basic thing. We want to estimate our tasks and plan the sprints based on that.
I went over endlessly examples and even tried to use the Jira Permium, Epics, Stroys and subtasks but nothing gives the required result.
Anyone can help here? Give me a link to real life examples?
If i use subtasks it is not very easy to sum the effort and this is really hard to manage.
For example:
Story: Login
Subtask: Server side
Subtask: Client side
Subtask: QA
Now the board need to be updated on the parent along with the subtasks all the time.. Hard to maintain.
Please HELP!!
