Core concepts
The five phases
Every iteration passes through five phases in order:
| Phase | What happens | Who's typically the owner |
|---|---|---|
| Product | Define what the change is, from a user-facing perspective | PM or designer |
| Engineering | Decide how it should be built, at the architecture level | Engineer |
| Planning | Break the work into a sequence of PRs | Engineer |
| Building | A coding agent or engineer implements each PR | Engineer |
| Built | All PRs merged | (read-only) |
Each phase narrows the work. Product defines what. Engineering defines how, at a high level. Planning defines the sequence. Building executes. Built is the finish line.
You move forward through phases via an action button at the top of the iteration. You can also reassign the iteration to a different person at any phase boundary, or even mid-phase.
For full detail on each phase, see Working in Itera.
