At Nestbot Robotics, one Developer only writes firmware, another only builds the companion app, and a third only handles hardware bring-up. A new engineering director wants to give them formal titles like 'Firmware Developer' and 'App Developer' and have each one accountable only for their own specialty's backlog items. How does this fit the Scrum Guide's description of the Developers?
Select an answer to reveal the explanation.
Short Explanation
Having a firmware specialty and an app specialty is normal — Developers bring different skills to the table all the time. What Scrum doesn't do is turn those skills into separate titles or separate ownership zones; the whole group is on the hook for the work together, not each person for their own slice.
Full Explanation
The Scrum Guide is explicit that Developers may have specialized skills and areas of focus, but accountability belongs to the Developers as a whole, and it names no sub-teams or hierarchy within that accountability. Assigning formal titles like 'Firmware Developer' with siloed ownership of specific backlog items reintroduces exactly the structure the Guide avoids: it turns a self-managing group into a set of individually accountable specialists, which works against the whole-team responsibility for the Sprint Backlog and the Increment. Making this contingent on Scrum Master approval misplaces the decision — the Scrum Master coaches on Scrum's structure, but titles and sub-accountabilities inside the Developers aren't something to be approved into existence, since the Guide doesn't recognize them at all. Treating it as a one-Sprint experiment to reconsider at the next Sprint Planning still misses the point: the issue isn't the duration, it's that formal specialty ownership conflicts with a core structural rule regardless of how long it's in place. In practice, specialization can and should still exist informally — the firmware-savvy Developer will naturally gravitate to firmware work — the difference is that no Product Backlog item is 'owned' by one person's title, and the Developers as a group remain answerable for the Sprint's outcome. A concrete check: when a Product Backlog item stalls, verify the whole group treats it as a shared problem rather than routing it to whoever holds the matching title.
