I want to implement a E2E dev process that is basically divided in three phases. 1. Discorvery-Phase in Kanban, 2. Delivery-Phase in Scrum for the development and 3. a Deployment-Phase in Kanban. It seems that it is not possible to put Scrum in the middle of two Kanban Boards, because Scrum wants to have a Done Status to close the Tickets. We do not want to close the TIckets in our 2. dev process. Instead the Tickets should go forward to the 3. phase - all this as one E2E process. Any suggestions? Would be nice ;-)
