Large projects require big thinking. Don't worry! With pinnery you are best prepared! You can attach an unlimited count of checkpoints to every card. When you are working on a certain task you can see it on the checklist and resolve the task step by step. So you ensure nothing gets forgotten.
Every card can have a whole subboard. The subboard works just like a normal board, cou can create columns and cards in it. Whenever a task in the subboard is in the process of being resolved, the information will be displayed in the main board where your card was originally assigned. You can assign different team members to the sub board.
