Features are typically mapped directly to Initiatives within the same Product. It seems that it would be less frequent that you map outside of that Product or Product Line. Yet when you try to do the mapping it shows all of the Initiatives across the whole organization. There is search functionality but this functionality is slow and requires knowledge of the key words to hit for that initiative.
Just showing the initiatives within that product would fit the 95% of scenarios, and could be something else to map outside. But right now inundated with options when trying to create that mapping. Worried that this will inhibit how well the tool scales to large organizations with tons of initiatives...
I run the on-boarding for my team to Aha and this has been repeatedly expressed.
Also you can't click on the Initiative from within the feature.
