It would be great if we could put an entire team into a plan, but some team members can only add something to a single bucket list and the others have read-only permissions. Is this possible? Here I think very strongly of agencies that work with development and concept and designers. One could create a kind of Scrum process where customer advisors can create tasks and afterwards the work can be carried out by the individual departments. Furthermore, there should then be a bucket list such as verification, here the customer advisor can comment again, upload images .... to list errors. After that, for example, the developer can fix the errors.
Is this possible in the foreseeable future?
Also see https://planner.uservoice.com/forums/330525-microsoft-planner-feedback-forum/suggestions/34806313-would-like-the-ability-to-add-a-person-to-just-one you should be able to share just a task with a single person, not a whole plan. But I voted for this too as I can see the use case... I'll move back to Trello or something if Planner doesn't get some resource soon - sadly, as I expected this functionality...
I've been looking for such a solution for a long time. The Scrum process is getting more and more important. It would be great if you could implement that in your software.
