We just need more details to accomplish that
Can we do it in 3 weeks (1 sprint)? or 1 sprint for backend and other
one for the frontend?
We discussed today.It depends on how much we want to use this
feature. Though it's a good feature, we might need to redesign all task
in the back-end and might need a new tab in the front which indicates
user what kind of message they want to register. Also just for the task
issue, simply we might just need to add some pairs of keys that provide
more information of the task so that the browser will identify which
user is running which tasks, in which case, we still need the browser
check over and over again whether one task is finished.
We might need to discuss more about this issue and if we want a new
design of the message deliver, it might need more time for both the
back-end and the front-end work for a long time since there hardly exist
one good solution for that. We need to design all my our own. And for
the task improvement proposal, it should be a much more quick job.
