Kanban and Blocked Work

Whats the best way to handle blocked work in a Kanban system?

  1. Do you increase the WIP limit, thus freeing up time for team members to work on something else?
  2. Do you keep the WIP limit as-is, and raise awareness by having people sit idle while the root cause of the blockage is pursued?

My thought is the proper long-term approach is probably #2, but #1 seems a lot easier to implement. (Image credit)
