This is a cool concept, but at the moment, we're finding this matrix too noisy, and it tends to sidetrack the discussion we'd like to have. With that, here are some features we'd like to see around this:
|Release time frame|
Thank you for the note. There are a few aspects of the existing functionality which can help you better leverage the Initiatives page for your own use.
It's currently possible to hide initiatives from appearing on the matrix. When clicking into an initiative, you can click on the "Show on roadmaps and charts" option to hide it from this matrix chart.
It's also possible to create a custom scorecard field on Initiatives, which would allow you create your own custom formula (and directly edit the drivers).
We don't currently have plans to suppress/remove the chart (based on community feedback) but hope that the points above will be helpful. Based on the above points, we'll mark this idea as already exists.
