In order to move stories between columns on the kanban board I can do 1 of 2 things:
- Drag and drop the story in the new column. However this has the undesired result of changing the overall ranking of the story.
- Expose the state as a drop down on the story and then select a new state. This preserves the overall ranking but the story stays 'done' (ie it has the green tick) from the previous column.
In both situations the story remains assigned to whoever it was previously assigned to.
It would, IMHO, be a significant improvement if the stories could have a couple of buttons on them which would allow you to move the story to the next (or previous) column and at the same time removed the 'done' status and assigned it to you. If these buttons were only visible when the story was 'done', then it would promote the correct kanban workflow of marking a story as done and then someone can 'pull' it by moving it across the board to the next column, and assigning themselves to the ticket.
