I am setting up Jira in my current employer. We have already some teams working with it and using Scrum as their development framework.
Now, the management told me they would like to know on what the teams are working and if they are delivering "on time".
I imagine that this is a recurring problem on agile: how to achieve transparency to the company regarding on what the teams have already worked on and are currently working on?
The management told they wanted something like a Gantt chart, so they could see what the teams have done so far and what they are doing, so they can compare to our roadmap.
I tried to use BigGantt, but it has some problems when a task has already started in a previous sprint, because the sprint start date is set as the earliest task start date.
How can I fix this problem in our projects?
