Explanation
In Scrum, estimates must come from the person who will actually do the work - making the assigned team member's estimate of 7 days the correct value to use. This is a core Agile principle: those closest to the implementation have the most accurate understanding of effort and complexity.
- A (2 days) is wrong because the Lead Architect is not doing the work; their estimate likely underestimates hidden complexity the implementer knows about.
- B (5 days) is wrong because the Product Owner defines what gets built, not how long it takes - the PO should not be estimating implementation effort at all.
- D (8 days) is wrong because the Scrum Master is a process facilitator, not a technical contributor; they have no basis for work estimates.
Memory tip: Think "Who owns the work owns the estimate." If you see a story where multiple roles give different estimates, always pick the developer/implementer - they have the ground-level knowledge that managers and architects lack.
