PSM-I Sample Questions Answers

The correct answer is B, because the Sprint Backlog is created during the Sprint Planning meeting. The Scrum Guide states that “the Sprint Backlog is the set of Product Backlog items selected for the Sprint, plus a plan for delivering the product Increment and realizing the Sprint Goal.”

The correct answer is E, because any of the above (or others) which are a decomposition of the selected Product Backlog items can be included in the Sprint Backlog. The Scrum Guide states that “the Sprint Backlog is the set of Product Backlog items selected for the Sprint, plus a plan for delivering the product Increment and realizing the Sprint Goal.” Therefore, any work items that help the Development Team achieve the Sprint Goal can be part of the Sprint Backlog.

During the Sprint Retrospective, the Scrum Team may add items to the Sprint Backlog for the next Sprint, as stated in [5]: “The purpose of each Sprint Retrospective is to plan ways to increase quality and effectiveness. The Scrum Team plans ways to implement improvements identified during this meeting into its way of working. By doing this it reinforces empiricism throughout its work. Improvements may be implemented at any time during a Sprint or they may be planned for subsequent Sprints.”

The correct answers are B, C, and D, because moving away from component teams toward feature teams may involve some challenges and trade-offs. Productivity may suffer when making this kind of move, as teams need to learn new skills, coordinate with other teams, and deal with legacy code. Getting support from the business side first helps, as they can provide the vision, value, and feedback for the features. Feature teams have less communication overhead, as they can deliver end-to-end functionality without depending on other teams.

According to the Scrum Guide1, each event in Scrum is a formal opportunity to inspect and adapt something. These events are specifically designed to enable critical transparency and inspection. Failure to include any of these events results in reduced transparency and is a lost opportunity to inspect and adapt. All events are time-boxed events, such that every event has a maximum duration. Once a Sprint begins, its duration is fixed and cannot be shortened or lengthened. The remaining events may end whenever the purpose of the event is achieved, ensuring an appropriate amount of time is spent without allowing waste in the process. The time-box for the Daily Scrum is 15 minutes or less for a one-month Sprint. Its location and time remain constant.

The correct answer is C, because the Development Team should inform the Product Owner so he/she can work with the CEO. The Scrum Guide states that “only the Product Owner has the authority to cancel the Sprint, although he or she may do so under influence from the stakeholders, the Development Team, or the Scrum Master.” Therefore, if the CEO wants to add a “very important” item to a Sprint that is in progress, he or she should communicate with the Product Owner, who can then decide whether to cancel or continue the current Sprint.

The correct answer is B, because the Scrum Guide states that “the Sprint Goal is an objective set for the Sprint that can be met through the implementation of Product Backlog. It provides guidance to the Development Team on why it is building the Increment.” Therefore, the Sprint Goal provides the Development Team with a target and overarching direction for the Sprint.

According to the Scrum Guide, a high-performance Scrum Team does not run a Release Sprint, as this is not a Scrum event. A Release Sprint is a term used to describe a Sprint that is dedicated to finalizing the product for release, such as fixing bugs, polishing features, or integrating components. This is contrary to the Scrum principle of delivering a potentially releasable Increment at the end of each Sprint, regardless of whether it is actually released or not. Therefore, the answer is false.

According to the Scrum Guide1, collaboration between the Product Owner and Developers is essential for creating valuable products. The Product Owner is accountable for maximizing value resulting from work by Developers. Developers are accountable for creating a plan for the Sprint, which includes selecting items from Product Backlog that they can complete within a Sprint. The Scrum Master is accountable for establishing Scrum as defined in the Scrum Guide. They do this by helping everyone understand Scrum theory and practice, both within the Scrum Team and the organization. Therefore, two valuable actions for a Scrum Master to take if the Product Owner is not collaborating with the Development Team during the Sprint are:

• Bring up the problem in the Sprint Retrospective, where the Scrum Team can inspect how they worked together and create a plan for improvements.
• Coach the Product Owner in the values of Scrum and incremental delivery, and help them understand their role and responsibilities in collaborating with Developers.

The other options are not valuable actions, as they may undermine trust, respect, and self-organization within the Scrum Team.

The correct answer is C, because as soon as possible in the Sprint, the Development Team should work with the Product Owner to remove some work or Product Backlog items if they realize they have selected too much work to finish in the Sprint. The Scrum Guide states that “the Development Team may renegotiate the selected Product Backlog items with the Product Owner. If the Development Team realizes it has too much or too little work, it may renegotiate the selected Product Backlog items with the Product Owner. The Development Team may also invite other people to attend to provide technical or domain advice.”

Three statements that are true about Scrum are:

• Each component of Scrum serves a specific purpose and is essential to Scrum’s success and your usage of Scrum to develop complex products.
• Scrum is a framework for developing and sustaining complex products.
• Scrum is based on empiricism and lean thinking.

These statements are supported by [6]: “Scrum is not a process, technique, or definitive method. Rather, it is a framework within which you can employ various processes and techniques. … Each component within the framework serves a specific purpose and is essential to Scrum’s success and usage. … The rules of Scrum bind together events, roles, artifacts, and rules governing their relationships. … The three pillars uphold every implementation of empirical process control: transparency, inspection, and adaptation.”

The correct answer is A, because a Sprint Retrospective should be held at the end of each Sprint. The Scrum Guide states that “the Sprint Retrospective is an opportunity for the Scrum Team to inspect itself and create a plan for improvements to be enacted during the next Sprint. … The Sprint Retrospective occurs after the Sprint Review and prior to the next Sprint Planning.”

Two techniques that would be most helpful in this situation are to discuss the impediments with the Development Team, and to prioritize the list and work on them in order, as stated in [3]: “The Scrum Master should facilitate a discussion with the Development Team to identify and prioritize the impediments that are blocking their progress. The Scrum Master should then work with the Development Team and other stakeholders to remove or mitigate these impediments as soon as possible.”

According to the Scrum Guide, every Scrum Team should have the competencies and skills needed to deliver an Increment in a Sprint. This means that the Developers can work on any aspect of the product without depending on others outside the team. The other options are not valid descriptions of what every Scrum Team should have, as they either imply that the Developers work in silos or rely on external people (such as a lead developer or representatives from different departments).

A Product Backlog item is considered complete when it meets the Definition of Done, as stated in [5]: “When a Product Backlog item or an Increment is described as “Done”, everyone must understand what “Done” means. Although this varies significantly per Scrum Team, members must have a shared understanding of what it means for work to be complete, to ensure transparency. This is the definition of “Done” for the Scrum Team and is used to assess when work is complete on the product Increment.”

According to the Scrum Guide, Developers do meet with stakeholders, especially during the Sprint Review and Sprint Planning events. The Product Owner is the primary person who interacts with stakeholders, but Developers also need to communicate with them to understand their needs, expectations, and feedback. The Product Owner may also invite stakeholders to provide clarifications or inputs during the Sprint.

According to the Scrum Guide, the timebox for a Sprint Planning event is 8 hours for a one-month Sprint, proportionally shorter for shorter Sprints. The other options are not valid, as they are either too long (such as monthly), too vague (such as whenever it’s done), or too short (such as 4 hours for a one-month Sprint).

All of the above topics should be discussed in the Sprint Review, as stated in [4]: "The purpose of this meeting is to inspect what was delivered during this sprint and adapt what we want to deliver next. This means we will discuss three things:

• What did we do this sprint?
• How did we do it?
• What do we want to do next?"

The correct answer is D, because this statement best describes the Sprint Review. The Scrum Guide states that “a Sprint Review is held at the end of the Sprint to inspect the Increment and adapt the Product Backlog if needed. During the Sprint Review, the Scrum Team and stakeholders collaborate about what was done in the Sprint.” Therefore, the Sprint Review is when the Scrum Team and stakeholders inspect the outcome of a Sprint and figure out what to do next.

A Product Owner releases each Increment when it makes sense, as stated in [2]: “The Product Owner decides when to release an Increment. This can be done at any time during or after a Sprint. The Product Owner may choose to release an Increment when it delivers enough value to customers or users, when it meets a market opportunity, when it reduces risk or uncertainty, or when it aligns with other business goals.”

The timebox for the Sprint Review is four hours for a one-month Sprint, as stated in [4]: “The Sprint Review is held at the end of the Sprint to inspect the Increment and adapt the Product Backlog if needed. During the event, the Scrum Team and stakeholders review what was accomplished in the Sprint and what has changed in their environment. Based on this information, attendees collaborate on what to do next. The Product Owner explains what Product Backlog items have been “Done” and what has not been “Done”; additionally, they discuss any changes to scope or budget or potential value. The entire group then collaborates on what to do next, so that the Sprint Review provides valuable input to subsequent Sprint Planning. The Sprint Review is a working session and attendees should inspect based on facts. A Sprint Review is held at the end of every Sprint for a maximum duration of four hours for a one-month Sprint.”

According to the Scrum Guide, the Product Owner does not make sure that the Developers select enough from the Product Backlog for a Sprint to satisfy the stakeholders. The Developers are responsible for selecting how much work they can do in a Sprint, based on their capacity and past performance. The Product Owner may influence them by ordering and clarifying the Product Backlog items, but does not control their selection.

 The Scrum Master should be concerned about the ability of the Development Teams to produce integrated Increments, as this is one of the goals of Scrum. The Scrum Master should also encourage the Development Teams to figure out a solution for themselves, as this fosters self-management and collaboration. The other options are not relevant or important for the Scrum Master in this situation.

According to the Scrum Guide1, the purpose of the Sprint Retrospective is to plan ways to increase quality and effectiveness. The Scrum Team inspects how the last Sprint went with regards to individuals, interactions, processes, tools, and their Definition of Done. Inspected elements often vary with domain, practices, and people involved. The Scrum Team identifies the most helpful changes to improve its effectiveness. The most impactful improvements are addressed as soon as possible. They may even be added to the Sprint Backlog for the next Sprint. The Sprint Retrospective is an opportunity for the Scrum Team to inspect itself and create a plan for improvements to be enacted during the next Sprint. The Scrum Master is part of the Scrum Team and should participate as a Scrum team member and facilitate as requested or needed.

According to the Scrum Guide1, the Scrum Master is accountable for establishing Scrum as defined in the Scrum Guide. They do this by helping everyone understand Scrum theory and practice, both within the Scrum Team and the organization.

According to the Scrum Guide, the Product Owner must participate in the Daily Scrum when he or she is actively working on items on the Sprint Backlog; however, they participate as a Developer, not as an authority figure. This means that the Product Owner can share progress, plans, and impediments with the other Developers and collaborate with them on delivering value. The other options are not valid reasons for the Product Owner to participate in the Daily Scrum, as they are either irrelevant (such as representing stakeholders or discussing impediments) or inappropriate (such as being asked by the Scrum Master).

The correct answers are B and C, because technical debt impacts transparency in these ways. It leads to false assumptions about the current state of the system, specifically of an Increment being releasable at the end of a Sprint, as it may contain hidden defects or incomplete functionality. It also results in future work being slowed down in unpredictable ways, as development progresses and code is added, the system becomes more difficult to stabilize and maintain.

According to the Scrum Guide, a Sprint concludes when the Sprint Retrospective is complete. This is the last event of the Sprint cycle, where the Scrum Team inspects itself and creates a plan for improvements. The other options are not valid indicators of the conclusion of a Sprint, as they are either irrelevant (such as the Product Owner deciding enough has been delivered) or incomplete (such as all tasks or Product Backlog items being done).

The Development Team must do as much work as it has told the Product Owner will be done for every Product Backlog item it selects in conformance with the definition of “Done”, as stated in the Scrum Guide1: “The Development Team works to forecast the functionality that will be developed during the Sprint. The Product Owner discusses the objective that the Sprint should achieve and the Product Backlog items that, if completed in the Sprint, would achieve the Sprint Goal. The entire Scrum Team collaborates on understanding the work of the Sprint.”

A Scrum Team is a cohesive unit of professionals that consists of one Product Owner, one Scrum Master, and Developers, as stated in the Scrum Guide: “The Scrum Team consists of one Scrum Master, one Product Owner, and Developers. Within a Scrum Team, there are no sub-teams or hierarchies. It is a cohesive unit of professionals focused on one objective at a time, the Product Goal.”

According to the Scrum Guide1, only people who are actively working on items in the Sprint Backlog participate in updating it during a Sprint; this includes tracking progress made on those items. This is typically done by Developers updating their remaining work every day after their Daily Scrum. The Development Team tracks this total work remaining at least for every Daily Scrum to project the likelihood of achieving their Sprint Goal.

According to the Scrum Guide, the amount of work required of the Developers to complete a Product Backlog item selected during the Sprint Planning is as much as is required to meet the Scrum Team’s Definition of Done. This means that the Developers must ensure that every item they work on is in a usable condition and meets all quality standards agreed upon by the team. The other options are not valid descriptions of the amount of work required, as they are either too vague (such as all development work and some testing or a proportional amount of time) or incorrect (such as fitting as much as possible or deferring work to the next Sprint).

According to the Scrum Guide1, each event in Scrum is a formal opportunity to inspect and adapt something. These events are specifically designed to enable critical transparency and inspection. Failure to include any of these events results in reduced transparency and is a lost opportunity to inspect and adapt. All events are time-boxed events, such that every event has a maximum duration. Once a Sprint begins, its duration is fixed and cannot be shortened or lengthened. The remaining events may end whenever the purpose of the event is achieved, ensuring an appropriate amount of time is spent without allowing waste in the process.

According to the Scrum Guide, the Scrum Team consists of three roles: the Scrum Master, who coaches and facilitates the team; the Product Owner, who manages and prioritizes the Product Backlog; and the Development Team, who delivers a potentially releasable Increment at the end of each Sprint. Users and customers are not roles on the Scrum Team, but they are stakeholders who may provide feedback and input to the product.

The correct answer is B, because the time-box for the Sprint Planning meeting is 8 hours for a monthly Sprint. The Scrum Guide states that “Sprint Planning is time-boxed to a maximum of eight hours for a one-month Sprint. For shorter Sprints, the event is usually shorter.”

The correct answers are B and C, because these are two responsibilities of a self-organizing Development Team. The Scrum Guide states that “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 structured and empowered by the organization to organize and manage their own work.” Therefore, the Development Team should pull Product Backlog items for the Sprint and do the work planned in the Sprint Backlog.

The correct answers are A, B, and D, because these techniques would be most helpful in this situation. Consulting with the Development Team may help identify the root causes of the impediments and possible solutions. Prioritizing the list and working on them in order may help reduce the backlog and focus on the most important or urgent issues. Alerting management to the impediments and their impact may help escalate the problems and get support from the organization.

According to the Scrum Guide1, the definition of “Done” is a formal description of the state of the Increment when it meets the quality measures required for the product. The definition guides the Development Team in creating a “Done” Increment. The definition of “Done” is created by the development organization (or Development Team if none is available from the development organization). The definition of “Done” may vary significantly per Scrum Team, depending on the context. One aspect of Scrum Teams inspecting how they work toward their Product Goal is that they improve their definition of “Done” over time. Therefore, one good way for a Scrum Team to ensure security concerns are satisfied is to add security concerns to the definition of “Done”. Another good way is to have the Scrum Team create Product Backlog items for each concern, as they are responsible for managing and refining the Product Backlog.

The correct answers are B, E, and F, because these activities would probably help the team in starting up. Having the Scrum Team members introduce themselves and give a brief background of their skills and work history helps build trust and rapport among them. Ensuring the team understands they need a definition of “Done” helps create transparency and alignment on the quality standards for the product. Asking the Product Owner to discuss the product or project, its history, goals, and context, as well as answer questions helps clarify the vision and value of the product.

According to the Scrum Guide, the Sprint Backlog may include any items that are a decomposition of the selected Product Backlog items, such as user stories, tasks, use cases, tests, or others. The Sprint Backlog is the Developers’ plan for the Sprint, and it contains all the work that they forecast they can do to achieve the Sprint Goal and create a “Done” Increment. The other options are not valid, as they are either too specific (such as user stories or tasks) or too vague (such as tests).

According to the Scrum Guide1, the Daily Scrum is an event for the Developers of the Scrum Team. The purpose of the Daily Scrum is to inspect progress toward the Sprint Goal and adapt the Sprint Backlog as necessary, adjusting the upcoming planned work. The Daily Scrum optimizes the probability that the Developers will meet the Sprint Goal. Every day, the Developers should understand how they intend to work together as a self-organizing team to accomplish the Sprint Goal and create the anticipated Increment by the end of the Sprint. If the frequency of the Daily Scrum were to be lowered to every two or three days, some key concerns would be:

• Opportunities to inspect and adapt the Sprint Backlog are lost, which may result in wasted work or missed dependencies.
• Impediments are raised and resolved more slowly, which may hinder the progress and quality of the work.
• The Sprint plan may become inaccurate, as changes in requirements, risks, or priorities are not reflected in a timely manner.

The other options are not valid concerns, as they are not aligned with Scrum values and principles.

References: Scrum Guide

According to the Scrum Guide1, ordering Product Backlog items is solely up to the Product Owner’s discretion. The Product Owner orders items in the Product Backlog to best achieve goals and missions. To do this, they optimize value by considering various factors such as cost and benefit, risk, dependencies, date needed, etc.

The correct answers are A and D, because a Development Team is responsible for resolving internal team conflicts and organizing the work required to meet the Sprint Goal. The Scrum Guide states that “development Teams are self-organizing. No one (not even the Scrum Master) tells the Development Team how to turn Product Backlog into Increments of potentially releasable functionality.” Therefore, a Development Team should manage its own work and resolve its own issues.

According to the Scrum Guide, the Development Team should do two things during the first Sprint: develop at least one piece of functionality and create an increment of potentially releasable software. These are the goals of every Sprint, regardless of its order. The other options are not things that the Development Team should do during the first Sprint, as they are either out of scope (such as making a plan for the rest of the project or defining major product features and release plan architecture) or unnecessary (such as analyzing, describing, and documenting requirements for subsequent Sprints).

According to the Scrum Guide, two actions that the Scrum Master should support in this scenario are forecasting the Product Backlog items that are most likely to meet the Sprint Goal and creating the Sprint Backlog, and discussing why this happened and what changes will make it less likely to recur during the next Sprint Retrospective. These actions are consistent with Scrum values and principles, such as empiricism, adaptation, and continuous improvement. The other options are not valid actions, as they are either wasteful (such as canceling the Sprint or continuing the Sprint Planning past its timebox) or ineffective (such as asking everyone to take more time to analyze the Product Backlog).

According to the Scrum Guide1, 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 structured and empowered by the organization to organize and manage their own work. The resulting synergy optimizes the Development Team’s overall efficiency and effectiveness. Cross-functional teams have all competencies needed to accomplish the work without depending on others not part of the team. The team model in Scrum is designed to optimize flexibility, creativity, and productivity.

The correct answer is D, because the recommended size for a Development Team is 3 to 9 members. The Scrum Guide states that “fewer than three Development Team members decrease interaction and results in smaller productivity gains. Smaller Development Teams may encounter skill constraints during the Sprint, causing the Development Team to be unable to deliver a potentially releasable Increment. Having more than nine members requires too much coordination. Large Development Teams generate too much complexity for an empirical process to be useful.”

The correct answer is B, because when multiple Scrum Teams work from the same Product Backlog, they should pull in work in agreement with the Product Owner. The Scrum Guide states that “multiple Scrum Teams often work together on the same product. One product goal unites them. Therefore, they must mutually define and comply with a definition of ‘Done’ that applies to their combined work product.” Therefore, they should collaborate and coordinate with each other and with the Product Owner to select Product Backlog items that align with their shared product goal.

According to the Scrum Guide, two things that the Scrum Team should do during the first Sprint are building at least one piece of valuable functionality and creating at least one valuable, useful Increment. These are the goals of every Sprint, regardless of its order. The other options are not things that the Scrum Team should do during the first Sprint, as they are either out of scope (such as defining major product features and a release plan architecture or making a plan for the rest of the project) or unnecessary (such as analyzing, describing, and documenting requirements for subsequent Sprints).

According to the Scrum Guide1, the purpose of the Sprint Retrospective is to plan ways to increase quality and effectiveness. The Scrum Team inspects how the last Sprint went with regards to individuals, interactions, processes, tools, and their Definition of Done. Inspected elements often vary with domain, practices, and people involved. The Scrum Team identifies the most helpful changes to improve its effectiveness. The most impactful improvements are addressed as soon as possible. They may even be added to the Sprint Backlog for the next Sprint. Therefore, two appropriate topics for discussion during a Sprint Retrospective are:

• Identifying high priority process improvements for the next Sprint.
• How the team collaborates.

The other options are not relevant or appropriate for the Sprint Retrospective.

There is no such thing as Sprint 0 in Scrum, as stated in [7]: “Sprint 0 is a term used by some people who use Scrum to describe an initial period before starting Sprints where they do some upfront planning or analysis. However, this is not part of Scrum and contradicts its principles of empirical process control, iterative delivery, and responding to change.”

According to the Scrum Guide1, the Sprint Retrospective is an opportunity for the Scrum Team to inspect itself and create a plan for improvements to be enacted during the next Sprint. The Sprint Retrospective occurs after the Sprint Review and prior to the next Sprint Planning. The purpose of the Sprint Retrospective is to plan ways to increase quality and effectiveness. The Product Owner is part of the Scrum Team and should participate as a Scrum Team member in the Sprint Retrospective.

References: Scrum Guide

 According to the Scrum Guide, a Scrum Team is not only allowed to meet with stakeholders during Sprint Review, but also during Sprint Planning and throughout the Sprint as needed. The Sprint Review is an opportunity for the Scrum Team and the stakeholders to collaborate on what was done in the Sprint and what to do next. However, it is not the only time that stakeholder feedback is welcomed and valued.

According to the Scrum Guide, Developers are self-managing, which means that they manage their own Sprint Backlog. They decide how to organize their work and collaborate effectively to deliver a valuable Increment that meets the Definition of Done and the Sprint Goal. The other options are not valid, as they imply that Developers manage things that are either determined by the Scrum framework (such as Sprint length), by collaboration with other roles (such as when to release or stakeholders for the Sprint Review), or by the Product Owner (such as Product Backlog ordering).

According to the Scrum Guide1, the Sprint Planning meeting has a time-box of eight hours or less for a one-month Sprint. The Scrum Master ensures that the meeting is time-boxed and keeps the Scrum Team focused on the objective. If the Development Team cannot forecast how many Product Backlog items it can complete, it should still start the Sprint and work on the most likely items to meet the Sprint Goal. The Sprint Backlog can be updated throughout the Sprint as more is learned. The Scrum Master should also support the team to discuss the reasons for the lack of clarity in the Product Backlog items and how to prevent it from happening again in the next Sprint Retrospective.

References: Scrum Guide

According to the Scrum Guide1, an Increment is a concrete stepping stone toward the Product Goal. Each Increment is additive to all prior Increments and thoroughly verified, ensuring that all Increments work together. In order to provide value, an Increment must be usable. Multiple Increments may be created within a Sprint. The sum of the Increments is presented at the Sprint Review thus supporting empiricism. However, an Increment may be delivered to stakeholders prior to the end of the Sprint. The Sprint Review should never be considered a gate to releasing value. Therefore, the best description of an increment of working software is additional features in a usable state that complement those delivered in previous iterations.

References: Scrum Guide

The Scrum Master should talk to the IT manager and explain that progress in Scrum comes from inspecting an Increment at the Sprint Review, as stated in [5]: “The Scrum Master should educate the IT manager about how Scrum works and how progress is measured. The Scrum Master should invite the IT manager to attend the Sprint Review where the Development Team demonstrates what was accomplished during the Sprint. The Scrum Master should also explain that status reports are not necessary in Scrum, as transparency is ensured by using artifacts such as Product Backlog, Sprint Backlog, and Increment.”

According to the Scrum Guide, the best approach for Scrum Teams in order to produce valuable Increments is to have each Developer work on the component where they feel that they can contribute. This means that the Developers can self-organize and collaborate effectively to deliver a valuable Increment that meets the Definition of Done and the Sprint Goal. The other options are not valid approaches, as they either imply that the Developers work in silos or rely on external people (such as developing functionality from beginning to end, working on an independent set of components, or working only as an independent layer of the system).

According to the Scrum Guide, the Product Owner is accountable for clearly expressing Product Backlog items, as he or she is responsible for managing and prioritizing the Product Backlog. The other options are not valid, as they imply that the Product Owner can be replaced by a business analyst, or that the Scrum Master or the Developers can express the Product Backlog items.

The correct answer is A, because Development Team membership should change as needed, while taking into account a short term reduction in productivity. The Scrum Guide states that “development Teams are cross-functional, with all of the skills as a team necessary to create a product Increment; development Teams are self-organizing. No one (not even the Scrum Master) tells the Development Team how to turn Product Backlog into Increments of potentially releasable functionality.” Therefore, changing Development Team membership may affect their cross-functionality and self-organization in the short term.

Correct Answer: C and E

Short Explanation: According to the Scrum Guide 20201, the product has one Product Backlog, which is the single source of work undertaken by the Scrum Team. The Product Backlog is ordered by the Product Owner, who is accountable for maximizing the value of the product resulting from the work of the Scrum Team. There should be only one Product Owner per product, who may represent the desires of a committee in the Product Backlog, but those wanting to change a Product Backlog item’s priority must address the Product Owner1. Having multiple Product Owners or Product Backlogs would create confusion, inconsistency, and waste in the Scrum process.

 According to the Scrum Guide1, when multiple Scrum Teams are working together on the same product, they must mutually define and comply with the same definition of “Done”, which includes creating an integrated Increment at least by the end of each Sprint. The Scrum Master should teach and coach the Developers that it is their responsibility to work with other Scrum Teams to create an integrated Increment that meets the definition of “Done”. The other options are not aligned with Scrum values and principles.

The correct answers are B and C, because these are the two primary ways a Scrum Master keeps a Development Team working at its highest level of productivity. The Scrum Guide states that “the Scrum Master serves the Development Team in several ways, including … removing impediments to the Development Team’s progress; facilitating Scrum events as requested or needed; and coaching the Development Team in self-organization and cross-functionality.” Therefore, by removing impediments and facilitating decisions, the Scrum Master helps the Development Team focus on their work and deliver value.

According to the Scrum Guide, the Product Owner has the final decision about the order of items in the Product Backlog, as he or she is responsible for maximizing the value of the product and the work of the Development Team. The other roles do not have this authority, although they may provide input and suggestions to the Product Owner.
