I am working with a company that is beginning to use Kanban for integrations. They have defined a process and built columns and status to visible represent priorities. My question is, the business will want to keep planning with the PO and architects some complex Boomi integrations to prepare for 3rd party/offshore developers, is it best to define the work need in the EPIC or how can I simply use a standard backlog? Today I have just Roadmap and Kanban board and we feel it would make better sense to have a backlog of stories and major tasks we need to create. Why shouldn't we take this approach?
