Expert Scrum Master Practice Test

Story points are estimates. Velocity is based on estimates and has a variance. We can use velocity to estimate the number of Sprints needed - but it is an estimation, only.

The Work Breakdown Structure is a traditional project management technique.

A Business Requirement Definition is a traditional business analysis document.

Given - When - Then is a template for writing acceptance criteria.

Acceptance criteria is a technique which supports not only testing but also the better understanding of complex or ambiguous requirements.

While Agile encourages collective code ownership, no one can give strong specialist skills and system knowledge to all Developers. The Product Owner should set his or her expectations accordingly.

In agile, we usually call the timebox an iteration and the outcome an increment. This is because the two approaches can be combined with synergy and used in this format in agile invariably. However, iterative development does not have to deliver increments at all. It simply means that features, functions, components are evolving from iteration to iteration, as more is learned about the nature of the product.

Definition of Ready is an arbitrary technique. When a Product Backlog item meets the Definition of Ready (e.g. refined, estimated, approved, has all details), the team can mark it as ready for Sprint Planning.

Product Backlog items are not necessarily user stories. A user story is just another optional agile technique from Scrum's perspective.

A user story does not have a mandatory format, though there are some popular templates.

Acceptance criteria are not a mandatory element of the user story.

The burndown chart measures the progress of work in a Sprint and can represent all the related metrics. However, it does not represent velocity from Sprint to Sprint.

The definition of "Done" should cover everything that is needed for a potentially releasable Increment.

If integration testing is needed for that, it should be part of the definition of "Done". Since the definition of "Done" is applied for all backlog items, it means that in our case integration testing is a prerequisite of claiming a backlog item "Done".

In Scrum, the Development Team is responsible for architectural decisions. One of the recommended approaches is the 'emergent architecture'.

Velocity is calculated from estimations and estimations are peculiar to a given team. Two teams may apply utterly different estimation techniques.
