True. All work the Scrum Team plans for the product comes from the Product Backlog. It is the single place where work is made visible and ordered.
Exam Question
True or False: All planned work for the Product done by the Scrum Team must originate from the Product Backlog.
A. True
B. False
Correct Answer
A. True
Why This Is the Correct Answer
The Scrum Guide says the Product Backlog “is the single source of work undertaken by the Scrum Team.” The Sprint Backlog is built from Product Backlog items selected in Sprint Planning, plus the plan for delivering them. Keeping all work in one place means the Product Owner can order everything by value and stakeholders can see what the team is working on. Work that bypasses the backlog becomes invisible and undermines transparency.
Why the Other Options Are Wrong
B. False Side channels for work, such as direct requests to Developers or a separate technical list, hide work from the Product Owner and stakeholders. Scrum deliberately funnels everything through the Product Backlog.
Exam Tip
“Single source of work” is exact wording from the Scrum Guide and is a common basis for True/False questions on PSPO I.
Key Takeaways
- The Product Backlog is the single source of the Scrum Team’s work.
- The Sprint Backlog is built from it in Sprint Planning.
