Who creates a Product Backlog Item's estimate?
Who creates a Product Backlog Item's estimate?
The Development Team is exclusively responsible for creating the estimates for Product Backlog Items. This is because the team members are the ones who will be performing the work and have the necessary understanding and expertise to make accurate estimates. This autonomy allows them to account for the complexities and uncertainties involved in each task. Although the Product Owner can provide clarity on business needs and priorities, the final estimation is made solely by the Development Team.
Scrum Guide says: “The Development Team is responsible for all estimates. The Product Owner may influence the Development Team by helping it understand and select trade-offs, but the people who will perform the work make the final estimate.”
E. The Development Team, alone. The Scrum Guide emphasizes that the Development Team is responsible for estimating the work required for Product Backlog Items during Sprint Planning. The Development Team should have the autonomy to estimate the effort required for each item based on their collective understanding and expertise. The other options (A, B, C, and D) do not accurately reflect the responsibility for estimating Product Backlog Items as per the Scrum Guide.

The development team after learning about the requirements from PO.
A is the correct answer.
