How does work flow from one state to the next in a team Kanban board?
A . During the daily stand-up, team members make decisions and discuss how to move the work
B. People working in the first state move the work to the next state
C. Team members pull work from the previous state when they can do so without impacting their current state WIP constraint
D. The Scrum Master moves the work from one state to the next to ensure ongoing progress within the team

Answer: C

Explanation:

The team will focus on moving the work items to DONE. Kanban is a PULL system and not a PUSH system. The work items are pulled as and when the team can work on and this goes all the way to the last state “Done”. WIP limits adjust demand to capacity at bottlenecks and enable the flow through the board.
