Scrum Test

What is the recommended size for a Development Team (within the Scrum Team)?

3 to 9 Why: Optimal Development Team size is small enough to remain nimble and large enough to complete significant work. Fewer than three Development Team members decreases interaction and results in smaller productivity gains. More than nine members simply requires too much coordination.

The maximum length of the Sprint Review (its time-box) is:

4 hours for a monthly Sprint. For shorter Sprints it is usually shorter. Why: Sprint Review is a four-hour time-boxed meeting for one-month Sprints. For shorter Sprints, the event is usually shorter.

What are the two primary ways a Scrum Master keeps a Development Team working at its highest level of productivity?

By facilitating Development Team decisions By removing impediments that hinder the Development Team

Who should know the most about the progress toward a business objective or a release, and be able to explain the alternatives most clearly?

The Product Owner Why: The Product Owner is the sole person responsible for managing the Product Backlog, which includes that the Product Backlog is visible, transparent, and clear to all, and shows what the Scrum Team will work on next.

Who has the final say on the order of the Product Backlog?

The Product Owner Why: The Product Owner is the sole person responsible for managing the Product Backlog.

Who is on the Scrum Team?

The Scrum Master The Product Owner The Development Team Why: The Scrum Team consists of the Scrum Master (manages the process), the Product Owner (decides what to do) and the Development Team (does the work).

Why is the Daily Scrum held at the same time and same place?

The consistency reduces complexity.

True or False: Scrum does not have a role called "project manager."

True

True or False: The purpose of a Sprint is to produce a done increment of working product.

True Why: The heart of Scrum is a Sprint, a time-box of one month or less during which a "Done", usable, and potentially releasable product Increment is created.

The Development Team should have all the skills needed to:

Turn the Product Backlog items it selects into an increment of potentially releasable product functionality. Why: The Development Team consists of professionals who do the work of delivering a potentially releasable Increment of "Done" product at the end of each Sprint. Development Teams are cross-functional, with all of the skills as a team necessary to create a product Increment.

The Product Backlog is ordered by:

Whatever is deemed most appropriate by the Product Owner. Why: The Product Owner decides what makes the most sense to optimize the value of the work being done by the Development Team.

Upon what type of process control is Scrum based?

Empirical Why: Scrum is founded on empirical process control theory, or empiricism. Empiricism asserts that knowledge comes from experience and making decisions based on what is known.

When is a Sprint over?

When the time-box expires. Why: The duration of a Sprint is fixed and cannot be shortened or lengthened.

Which of the below are roles on a Scrum Team?

Development Team, Product Owner, Scrum Master

The time-box for the Sprint Planning meeting is?

8 hours for a monthly Sprint. For shorter Sprints it is usually shorter. Why: Sprint Planning is time-boxed to a maximum of eight hours for a one-month Sprint. For shorter Sprints, the event is usually shorter.

Which statement best describes Scrum?

A framework within which complex products in complex environments are developed. Why: Scrum is not a process or a technique for building products; rather, it is a framework within which you can employ various processes and techniques.

When many Development Teams are working on a single product, what best describes the definition of "Done?"

All Development Teams must have a definition of "Done" that makes their combined work potentially releasable. Why: Scrum requires an Increment to be releasable. This is an Increment of product. Many teams working on a single product are expected to deliver such an Increment.

Development Team membership should change:

As needed, while taking into account a short term reduction in productivity. Why: Teams typically go through some steps before achieving a state of increased performance. Changing membership typically reduces cohesion, affecting performance and productivity in the short term.

Which two things does the Development Team do during the first Sprint?

Deliver an increment of potentially releasable software. Develop and deliver at least one piece of functionality. Why: The heart of Scrum is a Sprint, a time-box of one month or less during which a "Done", useable, and potentially releasable product Increment is created. This applies to every Sprint.

True or False: When multiple teams work together on the same product, each team should maintain a separate Product Backlog.

False Why: Products have one Product Backlog, regardless of how many teams are used. Any other setup makes it difficult for the Development Team to determine what it should work on.

What is the main reason for the Scrum Master to be at the Daily Scrum?

He or she does not have to be there; he or she only has to ensure the Development Team has a Daily Scrum. Why: The Scrum Master enforces the rule that only Development Team members participate in the Daily Scrum.

The CEO asks the Development Team to add a "very important" item to a Sprint that is in progress. What should the Development Team do?

Inform the Product Owner so he/she can work with the CEO. Why: The items selected for a Sprint have been selected as most valuable with the Product Owner. The items serve the Sprint's goal. No changes should be made that endanger the Sprint Goal. No one external to the Scrum Team can force changes on the Development Team (Sprint Backlog) and the Product Owner (Product Backlog).

The three pillars of empirical process control are:

Inspection, Transparency, Adaptation Why: Scrum is founded on empirical process control theory, or empiricism. Empiricism asserts that knowledge comes from experience and making decisions based on what is known. Three pillars uphold every implementation of empirical process control: transparency, inspection, and adaptation.

Which statement best describes the Sprint Review?

It is when the Scrum Team and stakeholders inspect the outcome of a Sprint and figure out what to do next. Why: Every event in Scrum, besides the Sprint which is a container for the other events, is an opportunity to Inspect AND Adapt.

The length of a Sprint should be:

Short enough to keep the business risk acceptable to the Product Owner. Short enough to be able to synchronize the development work with other business events. Incorrect answer No more than one month.

What is the role of Management in Scrum?

Support the Product Owner with insights and information into high value product and system capabilities. Support the Scrum Master to cause organizational change that fosters empiricism, self-organization, bottom-up intelligence, and intelligent release of software. Why: Management has no active role in the actual product development through Scrum. However, management external to the Scrum team is incredibly important in setting the vision and strategy to guide the overall direction of the organization.

Which of the following services are appropriate for a Scrum Master in regard to the Daily Scrum?

Teach the Development Team to keep the Daily Scrum within the 15 minute time-box. Why: The Scrum Master ensures that the Development Team has the meeting, but the Development Team is responsible for conducting the Daily Scrum. The Scrum Master teaches the Development Team to keep the Daily Scrum within the 15-minute time-box. The Scrum Master enforces the rule that only Development Team members participate in the Daily Scrum.

Who is required to attend the Daily Scrum?

The Development Team. Why: Only the people doing the work described on the Sprint Backlog need to inspect and adapt at the Daily Scrum. If the Scrum Master or Product Owner is also on the Development Team, they will need to be at the Daily Scrum. Otherwise, the Scrum Master simply has to make sure the Development Team knows how to conduct a Daily Scrum and does so.

The Development Team should not be interrupted during the Sprint. The Sprint Goal should remain intact. These are conditions that foster creativity, quality and productivity.

The Sprint Backlog is fully formulated in the Sprint Planning meeting and does not change during the Sprint. Why: The Sprint Backlog makes visible all of the work that the Development Team identifies as necessary to meet the Sprint Goal. The Development Team modifies the Sprint Backlog throughout the Sprint, and the Sprint Backlog emerges during the Sprint.

When might a Sprint be abnormally cancelled?

When the Sprint Goal becomes obsolete. Why: A Sprint can be cancelled before the Sprint time-box is over. A Sprint would be cancelled if the Sprint Goal becomes obsolete. This might occur if the company changes direction or if market or technology conditions change.
