When you have a work stream that manages perpetual streams of work (nested/organized by client), using EPICS that remain open, with linked stories that get executed (open/resolved/closed) seems to skew reporting (time to close, avg time in status, etc.). How do we classify this work, so that we have a history by client of all work requests, features, etc that get executed. Using tags and labels seems to classify and group the work, but then you can't see the details and history - that only allows you to pull data by tag/label - we need to have all work (and the history) roll up to a level ...so is this best achieved using Initiatives, or Programs vs. trying to keep Epics open indefinitely? Please advise.
