I am Managing a mobile app product. it contains backend team, design team, and flutter (mobile) team. User stories are usually consisting of subtasks, that involves both, backend, design and mobile team.
My questions are,
- How to estimate such a story, since the estimation of the mobile team, is way higher than the design team and is completely different by the dev team? which estimation will be taken into account?
- should these subtasks be really subtasks in Jira story, or should it be just tasks that is linked to the story as its parent? the reason for this question is that, when it is subtasks, we can't separately consider it done, because we estimate the story itself, and not the subtasks, then lots of problems happen, such as: I can't know how much points each developer has, 2- If the sprint ends before we finish a whole story, its story points are not counted in the report, even if it was 90% done of it, and then the velocity and burndown charts doesn't reflect the real effort that the team can do within a sprint.
I would really appreciate some practical tips of how to manage such a situation
