Hi,
I am a scrum master and have been told that we need to hit a deadline with certain scope.
In turn to meet this deadline the team have created a plan (similar to Gantt chart due to dependencies) with me facilitating. It is split into what we intend to carry out in the next four sprints to meet the deadline.
We have then reviewed this and adjusted this in refinement. In planning the team agree whether they are ok take what has been selected in the sprint.
