For the larger projects there is definitely non-programming tasks that need to be captured and tracked. For example, with the rewrite there were training sessions, documentation, help videos, and communications that all needed to be done. Those were non-development tasks that needed to be done and tracked. Plus, all of the pre-development work like requirements gathering, drafting the documents that detailed each piece, etc. So, yeah, we kinda need more than just the dev component.
I really want to move on from Trello as we've grown way past it. But with the recession not sure if now is the time since everything else costs money.
