Question 5

The 'Cone of Uncertainty' is a concept that illustrates a key principle of Agile planning and estimation. What does this concept primarily demonstrate?

Accepted Answer

Estimates become more accurate as a project progresses and more is known.

Answer

A team's velocity must increase over the course of a project.

Answer

The project scope must be fixed at the beginning to allow for accurate estimates.

Answer

Relative estimation is always four times less accurate than time-based estimation.

Question 6

Which of the following is a primary advantage of using a relative estimation technique like Story Points instead of a time-based estimation technique like ideal hours?

Accepted Answer

Story Points abstract the estimate to include complexity, risk, and effort, which fosters consensus and avoids issues with varying skill levels.

Answer

Story Points provide a precise delivery date to stakeholders at the beginning of the project.

Answer

Story Points are directly convertible to a fixed number of hours, making them easy for managers to understand.

Answer

Story Points eliminate the need to break down large features into smaller user stories.
