What would be the best project/board for this?

[Lukasz]

I have 3 projects.

Each project has tasks. These tasks have subtasks. 

I would like to have it on one board.

Hi @Lukasz ,

I think that a Kanban Board with  Swimlanes based on Projects, can be a good option to see all in the same Board.

Team managed or company managed?
