What are peoples opinions on sub tasks should they be used for teams? What use cases do you leverage sub tasks for vs using tasks and stories?
I will tell you that our teams use Sub-tasks very sparingly because of the limitations/tightness of the connection with parents. We also do Kanban and not Scrum so that probably helps to not rely on Sub-tasks.
But we leave it up to each team to decide if they want to use them. I personally rarely use them. I try to figure out another way to get what I need without using them. My two cents. :-)
We use sub-tasks. We use stories for user requirements. We use tasks for technical requirements or tasks. We add sub-tasks to both stories and tasks. The sub-tasks are assigned to the person doing the work. We only prioritize and estimate at the story/task level. The sub-tasks are just a breakdown of the work by person. Ideally, sub-tasks can be completed in 8 hours or less - not always the case though.
