PSM I Study Questions
When many Development Teams are working on a single product, what best describes the definition of "Done?" A) All Development Teams must have a definition of "Done" that makes their combined work potentially releasable. B) Each Development Team defines and uses its own. The differences are discussed and reconciled during a hardening Sprint. C) It depends. D) Each Development Team uses its own but must make their definition clear to all other teams so the differences are known.
A) 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: A) As needed, while taking into account a short term reduction in productivity. B) Every Sprint to promote shared learning. C) Never, because it reduces productivity. D) As needed, with no special allowance for changes in productivity.
A) 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.
How much work must a Development Team do to a Product Backlog item it selects for a Sprint? A) As much as it has told the Product Owner will be done for every Product Backlog item it selects in conformance with the definition of "Done". B) Analysis, design, programming, testing and documentation. C) As much as it can fit into the Sprint. D) All development work and at least some testing.
A) The purpose of each Sprint is to deliver Increments of potentially releasable functionality that adhere to the Scrum Team's current definition of "Done".
Which three behaviors demonstrate that a team is NOT self-organizing and are NOT following the Scrum Guide? A) The Development Team invites external people to the Sprint Planning to ask them how to turn a Product Backlog item into an Increment via a complete and detailed Sprint Backlog. B) The Development Team has all the skills needed to create a releasable Increment. C) The Development Team creates their own sprint backlog, reflecting all work that is part of the definition of "Done". D) Stakeholders attend the Daily Scrum to check progress and work with the Scrum Master to optimize the functional scope for the Sprint. E) The Development Team members are working within the boundaries of their functional description and nicely handing off work from analyst to developer to tester to integration. F) Development Team members collaboratively selecting their own work during the Sprint.
A, D, & E) 1. The Daily Scrum is for the Development Team and attended by the Development Team. It should not be used by external stakeholders to check progress. 2. During Sprint Planning the Scrum Team should be crafting the Sprint Goal based on the set of Product Backlog items selected for the sprint. The Development Team identifies the necessary work to meet the Sprint Goal. 3. Scrum Development Team members don't have titles, and no sub-teams; such as, testing, architecture, or operations are recognized. Accountability belongs with the Development Team as a whole, regardless of whether team members have specialized skills.
Which statement best describes the Sprint Review? A) It is a mechanism to control the Development Team's activities during a Sprint.

B) Every event in Scrum, besides the Sprint which is a container for the other events, is an opportunity to Inspect AND Adapt.
The Development Team should have all the skills needed to: A) Do all of the development work, except for specialized testing that requires additional tools and environments. B) Turn the Product Backlog items it selects into an increment of potentially releasable product functionality. C) Complete the project as estimated when the date and cost are committed to the Product Owner.
B) 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: A) Items are randomly arranged. B) Whatever is deemed most appropriate by the Product Owner. C) Least valuable items at the top to most valuable at the bottom. D) Risk, where safer items are at the top, and riskier items are at the bottom. E) Size, where small items are at the top and large items are at the bottom.
B) The Product Owner decides what makes the most sense to optimize the value of the work being done by the Development Team.

B) Teach the Development Team to keep the Daily Scrum within the 15 minute time-box. C) Facilitate in a way that ensures each team member has a chance to speak. D) Lead the discussions of the Development Team. E) All answers apply.
B) 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.
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. (Which one the following answers is FALSE?) A) The Development Team may work with the Product Owner to remove or add work if it finds it has more or less capacity than it expected.

D) The Product Owner can help clarify or optimize the Sprint when asked by the Development Team.
B) 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.
The time-box for a Daily Scrum is? A) 4 hours. B) 15 minutes. C) The same time of day every day. D) Two minutes per person. E) 15 minutes for a 4 week sprint. For shorter Sprints it is usually shorter.

C) 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.

D) 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.
True or False: The Scrum Team should choose at least one high priority process improvement, identified during the Sprint Retrospective, and place it in the Product Backlog.
False, to ensure continuous improvement, the Sprint Backlog rather than the Product Backlog includes at least one high priority process improvement identified in the previous Sprint Retrospective meeting.
True or False: The purpose of a Sprint is to produce a done increment of working product.
True, 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 time-box for the Sprint Planning meeting is? A) 4 hours. B) Monthly. C) 8 hours for a monthly Sprint. For shorter Sprints it is usually shorter. D) Whenever it is done.
C) Sprint Planning is time-boxed to a maximum of eight hours for a one-month Sprint. 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? A) By starting and ending the meetings at the proper time B) By facilitating Development Team decisions C) By removing impediments that hinder the Development Team D) By keeping high value features high in the Product Backlog
B & C) A Scrum Master is a servant-leader for the Development Team. Facilitation and removing impediments serves a team in achieving the best productivity possible.
Upon what type of process control is Scrum based? A) Complex B) Empirical C) Defined D) Hybrid
B) 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.
True or False: It is mandatory that the product increment be released to production at the end of each Sprint.
False, The product increment should be usable and releasable at the end of every Sprint, but it does not have to be released.
What is the role of Management in Scrum? A) 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. B) Identify and remove people that aren't working hard enough. C) Continually monitor staffing levels of the Development Team. E) Monitor the Development Team's productivity.
A) 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.
When does a Development Team member become the sole owner of a Sprint Backlog item? A) Whenever a team member can accommodate more work. B) During the Daily Scrum. C) At the Sprint planning meeting. D) Never. All Sprint Backlog Items are "owned" by the entire Development Team, even though each one may be implemented by an individual development team member.
D) Sprint Backlog and all of its items are collectively owned by the Development Team. No individual team member can claim ownership over an item as this would block communication and collaboration.
When might a Sprint be abnormally cancelled? A) When the Sprint Goal becomes obsolete. B) When it becomes clear that not everything will be finished by the end of the Sprint. C) When the sales department has an important new opportunity. D) When the Development Team feels that the work is too hard.
A) 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.
What does it mean to say that an event has a time-box? A) The event must happen by a given time. B) The event must happen at a set time. C) The event must take at least a minimum amount of time. D) The event can take no more than a maximum amount of time.
D) Time-boxed events are events that have a maximum duration.
True or False: When multiple teams work together on the same product, each team should maintain a separate Product Backlog.
False, 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 recommended size for a Development Team (within the Scrum Team)? A) 3 to 9 B) Minimal 7 C) 7 plus or minus 2 D) 9
A) 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.
Who is on the Scrum Team? A) The Scrum Master B) The Product Owner C) The Development Team D) Project Manager E) None of the above
A, B, & C) 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).
Which of the below are roles on a Scrum Team? A) Customers B) Development Team C) Users D) Scrum Master E) Product Owner
B, D, & E) The Scrum Team consists of a Product Owner, the Development Team, and a Scrum Master.
