What it is
Provide structure in the backlog and map to roadmap themes or objectives. Each epic has a goal, hypothesis, and success criteria — not just a name.
Concrete example
Epic: “Invoicing 2.0,” with stories for tax handling, partial payments, and invoice templates.
When to use it
Anytime a roadmap theme decomposes into 3+ stories. Replace name-only epics with goal-bearing epics.
What Product Joi delivers
Epic charter: goal, hypothesis, target metric, success criteria, scoped story list, dependencies, and milestone checkpoints.
