I'm using personal kanban and currently have 2 separate boards - one for job hunting and school, one for household chores. Each is has color coded task types in addition. I don't switch between boards very often during the day - generally only when burn out on job hunting approaches.
However, in the fall I will be back to taking online courses that will be pretty intense. I'm thinking of setting up a separate board for each course, still with the self imposed rule of not switching between boards.
Is it wise to have separate kanban boards? Should I more strictly limit the number of WIP (1 or 2 instead of 3) per board or impose a limit across all boards? Or should I try to mix this all into one board? (these boards are online, not physical)
