It became a best practice to define a feature request, improvements etc. as a parent issue and
to break down the implementation tech details into sub-tasks.
Unfortunately, everybody with permission Create Issues is able to create sub-tasks.
There is no way for project lead to enforce a
- "How to create a sub-task" policy
My improvement request: please add a new permission type
- Create Sub-Tasks
Based on this improvement, a project lead will be able decide whom to give the permission
to create sub-tasks (e.g. to experienced team members), and not give (e.g. customers, etc.)
BTW, please consider to rename sub-task to sub-issues to become more consistent - check JRA-6923.
