Because this feature doesn't exist, my current way of managing things is to repurpose Releases to be PI's which causes a few problems:
- the portfolio view becomes useless, showing a number of consecutive increments. It should show outcomes being delivered through the releases.
- with Releases now only able to be used for planning capacity, to have a view of how a number of features come together to deliver an outcome over a number of increments, you need to use Initiatives. Unfortunately there is now nothing that ties the initiatives together - and in the Aha model, it should be the initiative that ties the Releases together - saying "these releases are trying to deliver this greater outcome which is represented by this initiative".
