Let's say you have a project plan and none of the issues have estimates. Is it possible to visualise progress using Portfolio for JIRA or are estimates required?
If it is possible, how can we do this?
Do you consider other add-ons as a help for this problem? We have customers using Portfolio together with Structure for measurements and visualization.
A hierarchy in Structure can be built automatically based on a Portfolio plan, and then you can use highly configurable Progress column or formula-based calculations in Structure to get the number you need.
