It reminded me of a colleagues' board, but on a smaller scale. I really like the fact that you can't put everything on it, that it keeps you 'to the point' and focussed.The board, at Snapper known as "a Gina board" is used to organise personal tasks. The standard workflow is "Backlog" (stuff I want to/have to do), "Queue" (the subset of the Backlog that’s up to be worked on next), "In Progress" and "Done".The limited space for each of those workflow states imposes a natural limit on the number of items in each state, e.g. no more than 4 stickies fit into the "In Progress" area and getting more than 8 items into your "Queue" column is impossible. The lowest area on the board is either used as an expedite lane or for little inspirational messages and reminders.
