      Someone might be the PO for a single IT project. Or be in the early
      stages of inventing and envisioning some new idea. Or getting a
      program written to perform some technical calculation.

      It does happen.

        XP differs from kanban in many of the same ways as Scrum. It
        is batch pull, not continuous pull. Instead of a sprint, XP
        calls it an iteration. In XP, like scrum, but not kanban, each
        story has a high level estimate attached to it during release
        planning, which is similar, but somewhat different from
        backlog grooming in scrum.
