Hi all. Happy New Year!
Is there a way I can get aggregates of aggregates (for example, in a card tree). I’d like to use Task cards and link them to Story cards. I’d like each of those Task cards to have an effort estimate in hours upon which I can create an aggregate estimate calculation per Story to get total hours of all tasks per Story. That, I believe, I can do now in v2.1 of Mingle. I believe I can also use that newly created aggregate calculation (at the Story level) in other calculations at the Story level (for example, I can divide that hour total number by X to get an estimate of days of effort as opposed to hours for each Story).
What I am not sure about, however, is what I want to do next. I want to be able to link stories (which, remember, now have tasks with estimates in hours associated with them) to iterations and then also have aggregate calculations at the iteration level (total hours for all stories in that iteration, for example). I don’t think there’s a way I can currently do that in Mingle (but that’d be a GREAT addition to the tool).
Does anyone have recommendations for how to address this need?
Aggregates of Aggregates

Anyone have any ideas on this? I'd love to be able to implement this.
Patrick, although there isn't a concept of an aggregate of aggregates, you can accomplish the same thing by creating the same aggregate at a higher level in the tree. If I understand your setup correctly, you could create an iteration aggregate which sums up the estimates on the tasks in that iteration.
Say you have a fixed number of iterations per release. Aggregates of aggregates is the ideal way to get the average velocity over all iterations.
Such a feature would be, in my opinion, desireable. I would be interested in a workaround, should anyone know one.
Any chance we can include this in 3.0? At PMI, we're using Mingle in a few different ways (adjusting Agile to work within PMI) and we need some other functionality that's not currently available (and that, I would think, would be desired for large enterprises using Mingle).

We are currently not intending to build this as we see the workaround that Jay suggested to be acceptable at the moment. Can you explain why this doesn't work for you guys so we can consider this again?
Also, as this is related, I wanted to let you know we will be including the functionality to build formulas using aggregates and also the ability to create conditional aggregates in Mingle 3.0.
Thanks Suzie
