I have a question regarding kanban board and handling defects that are found in testing. The case is this:
- User story moves through "Development'' and goes to "Testing'' column on board. Defect is found in the period of testing. Where should that US be held now?
a) In the same column and flagged but with new status - maybe "Defect opened''
b) Returned back to "To do'' - but then we go LEFT instead to RIGHT on the kanban board
c) In the same column with the same status "Testing''
