Consider the following iteration planning tasks where a tester can provide value: Break down user stories into tasks (particularly testing tasks) Estimate test effort for all testing tasks Identify and refine functional and non-functional aspects of the test object Which ONE of the following tasks should be ADDED to the above list?

During iteration planning, a tester's role is to ensure quality is built in from the start. The provided list covers task breakdown and estimation. A crucial addition is the proactive analysis of user stories. By participating in detailed risk analysis, testers help identify potential quality problems early. They also assess the testability of user stories and their acceptance criteria, ensuring that requirements are clear, consistent, and verifiable. This prevents defects and clarifies the scope of testing required for the iteration.

A. The test strategy is a high-level document, typically defined for the entire project or release, not within each iteration planning session.
C. Planning for the entire release is a higher-level activity (release planning), distinct from the more detailed planning for a single iteration.
D. The product owner is primarily responsible for writing user stories; testers collaborate to refine them and ensure they are testable, but not to write them initially.
