A project portfolio management process allows an organization to assess the effectiveness of its projects and find ways to improve them.
It also helps identify when a project or group of projects should be stopped or completed early.
This helps avoid situations where too many resources are tied up in unsuccessful projects and can free up resources for more promising projects.
It's crucial for this process to work you have accurate data from ongoing projects. That's where Portfolio Maps for Jira comes into play. It connects your high level portfolio plan to actual Jira data.
