I have a Client using Epics instead of User Stories to build and manage his Product Backlog (SAP Hana conversion). His Product backlog only feature Epics NO US. Epics have almost the same structure as User Stories i.e. They are described the same way: " <As a User>< xxxxx> etc..." It has acceptance criteria, DoD, DoR, priority. Epics are broken down in User Stories during Sprint Planning and are used along side their relevant tasks during Daily Scrums. Might I have your views about this unusual way of working and the potential risks that this might represent. Thanks.
