Notify Roadmap Stakeholders if an upcoming release is over/underplanned

What is the challenge?

In our company, many stakeholders steer the contents of our product roadmap. It would be great if those stakeholders could be automatically informed if an upcoming release is over/underplanned.

What is the impact?

Better planning because we inform the stakeholders upfront that there is no or too much capacity in an upcoming release

Describe your idea

Warning notification that is triggered if a release that is due x days in the future has less than less 50% or more than 150% usage of its capacity.
