PSM-I Professional Scrum Master I Question and Answers

The correct answer is D, because one of the services that a Scrum Master can provide in regard to the Daily Scrum is to teach the Development Team to keep the Daily Scrum within the 15 minute time-box. The Scrum Guide states that “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.”

 According to the Scrum Guide, the Daily Scrum is held at the same time and same place to reduce complexity and promote consistency. The other options are not valid reasons for holding the Daily Scrum at the same time and same place, as they are either irrelevant (such as naming the place) or incorrect (such as being demanded by the Product Owner or booking rooms in advance).

The correct answer is A, because a good first question for you to suggest the group thinks about when forming into teams is how will we make sure all teams have the right amount of expertise. This question helps the group consider the cross-functionality and self-organization of the Development Teams, which are essential for delivering a potentially releasable Increment every Sprint.

The correct answers are B and D, because these are the most appropriate responses for the Scrum Master. The Scrum Master should coach the team on why the Daily Scrum is important as an opportunity to update the plan, inspect the progress, and synchronize the activities of the Development Team. The Scrum Master should also learn why the Development Team wants this and work with them to improve the outcome of the Daily Scrum, rather than imposing a decision or accepting their request without question.

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, if a Product Backlog item worked on during the Sprint does not meet the definition of “Done”, two things that should happen with the undone Product Backlog item are:

Put it on the Product Backlog for the Product Owner to decide what to do with it, as they are accountable for effective Product Backlog management and ordering.

Do not include the item in the Increment this Sprint, as it does not meet the quality standards and may compromise value.

The other options are not appropriate, as they may compromise transparency, inspection, or adaptation.

According to the Scrum Guide, the Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product1. The Definition of Done is created by the Developers and it is used to assess when work is complete on the product Increment1.

The Scrum Guide also states that the Definition of Done may vary significantly per Scrum Team, depending on the context. The Definition of Done evolves over time and becomes more stringent as the Scrum Team matures1. Therefore, it is important for the Scrum Team to regularly inspect and adapt the Definition of Done to reflect their current situation and needs.

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 Sprint1. The Sprint Retrospective focuses on three questions: What went well in the Sprint? What could be improved? What will we commit to improve in the next Sprint?1 These questions can help the Scrum Team identify potential changes to the Definition of Done that would increase the quality and value of the product.

Option A is incorrect because Product Backlog refinement is not a formal Scrum event, but rather an ongoing activity that can happen at any time during the Sprint1. Product Backlog refinement is mainly concerned with adding detail, estimates, and order to Product Backlog items1. Changing the Definition of Done during Product Backlog refinement could cause confusion and inconsistency among the Developers and the Product Owner.

Option C is incorrect because Sprint Planning is a time-boxed event that initiates a Sprint by defining a Sprint Goal and selecting Product Backlog items that deliver one coherent function1. Sprint Planning is based on the current state of the Product Backlog and the latest Definition of Done1. Changing the Definition of Done during Sprint Planning could disrupt the flow of the event and affect the scope and feasibility of the Sprint.

Option D is incorrect because prior to starting a new project is not a specific time in Scrum. Scrum does not prescribe any phases or stages for a project, but rather an empirical approach that relies on frequent inspection and adaptation of both the product and the process1. Changing the Definition of Done before starting a new project could be premature and irrelevant, as the Scrum Team may not have enough information or experience to define what ‘Done’ means for their product.

According to the Scrum Guide, two valid actions that the Developers can take when they realize that the workload may be greater than their capacity to complete the work are ensuring that the Scrum Team is aware, starting the Sprint, and monitoring progress, and removing or changing selected Product Backlog items. These actions are consistent with Scrum values and principles, such as transparency, adaptation, and collaboration. The other options are not valid actions, as they are either wasteful (such as recruiting additional Developers or canceling the Sprint) or unsustainable (such as working overtime).

According to the Scrum Guide, a Scrum Team must release each Increment when it makes sense to do so, based on the value and feedback obtained from stakeholders. The decision to release an Increment is made by the Product Owner, who is responsible for maximizing the value of the product and the work of the Development Team. The other options are not valid, as they imply that releasing an Increment is either mandatory (such as after every Sprint), conditional (such as when the product is free of defects), or irrelevant (such as when the Scrum Team finishes their work).

The correct answers are A and D, because these ways of creating Development Teams are consistent with Scrum’s values. Allowing existing teams to propose how they would like to organize into the new structure respects their self-organization and empowerment. Bringing all the developers together and letting them self-organize into Development Teams also respects their autonomy and collaboration.

According to the Scrum Guide, the action that the Scrum Master should take when the Team decides that a Sprint Retrospective is unnecessary is to begin facilitating productive and useful Sprint Retrospectives. The Sprint Retrospective is an essential event for the Scrum Team to inspect itself and create a plan for improvements to be enacted during the next Sprint. The Scrum Master is responsible for ensuring that this event takes place and that positive outcomes are achieved. The other options are not valid actions, as they either imply that the Scrum Master complies with or ignores the decision of the Team (such as complying with it, calling a meeting with senior management, or consulting with the Product Owner), which is not consistent with Scrum values and principles.

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 correct answer is B. To present the Scrum Teams with insights and resources that help them improve. According to the Scrum Guide1, “The role of management in Scrum is to support the Product Owner with insights and information into high-value product and system capabilities.” Management also helps the Scrum Team by providing an environment that fosters agility, learning, and collaboration2. Management does not directly control or monitor the work of the Developers, nor does it interfere with the self-organization and autonomy of the Scrum Team3. Management’s function in Scrum is to enable and empower the Scrum Team to deliver value and continuously improve.

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 best two answers are B and D. These two ways of dealing with regulatory compliance issues are consistent with Scrum’s values and principles, as they allow the Scrum Team to deliver valuable and potentially releasable increments of the product while meeting the necessary standards and regulations. They also enable the Scrum Team to inspect and adapt their compliance strategy based on feedback and changing requirements.

A is not a good answer because it creates a separate silo of responsibility for compliance issues, which can lead to delays, conflicts, and inefficiencies. It also violates the Scrum value of transparency, as the compliance team may not have full visibility into the product development process.

C is not a good answer because it implies a waterfall approach that assumes all the compliance requirements are known and fixed upfront, which is rarely the case. It also reduces the flexibility and responsiveness of the Scrum Team, as they may have to follow a rigid plan that does not reflect the current reality of the product or the market.

The correct answers are A, C, and E, because these are feedback loops in Scrum. The Sprint Review is a feedback loop that allows the Scrum Team and the stakeholders to inspect the Increment and adapt the Product Backlog. The Sprint Retrospective is a feedback loop that allows the Scrum Team to inspect itself and create a plan for improvements. The Daily Scrum is a feedback loop that allows the Development Team to inspect its progress and plan its work for the next 24 hours.

When a Development Team determines that it will not be able to finish the complete forecast, both the Product Owner and the Development Team have to be present when reviewing and adjusting the Sprint work selected, as stated in [6]: “If there is not enough work remaining for all members of a Development Team then they can renegotiate scope with their Product Owner. If there is too much work remaining then they can also renegotiate scope with their Product Owner.”

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.

According to the Scrum Guide, the Developers are accountable for tracking the remaining work toward the Sprint Goal, as they are responsible for creating a valuable Increment that meets the Definition of Done and the Sprint Goal. The other options are not valid, as they imply that someone else outside the Development Team (such as the Scrum Master, the Product Owner, or the Project Manager) is accountable for tracking the remaining work, which is not consistent with Scrum values and principles.

 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.

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.

According to the Scrum Guide, Scrum is a framework to generate value through adaptive solutions for complex problems. It is based on empiricism, self-organization, and collaboration. The other options are not accurate descriptions of Scrum, as they are either too rigid (such as a defined and predictive process or a complete methodology), too vague (such as a cookbook), or irrelevant (such as scientific management).

The correct answer is A, because the Product Owner does not determine how many Product Backlog items the Development Team selects for a Sprint. The Scrum Guide states that “the number of items selected from the Product Backlog for the Sprint is solely up to the Development Team. Only the Development Team can assess what it can accomplish over the upcoming Sprint.” Therefore, the Development Team is responsible for choosing the scope of work for a Sprint.

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, in order to turn Product Backlog items into an Increment of potentially releasable product functionality, the Development Team should have all the skills needed.

References: Scrum Guide

 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, self-organization is one of the essential characteristics of Scrum Teams. Self-organizing teams choose how best to accomplish their work, rather than being directed by others outside the team. Self-organization enables teams to deliver faster and better results by harnessing their creativity and skills. Some benefits of self-organization are:

Increased creativity, as team members have more freedom and autonomy to explore new ideas and solutions.

Increased self-accountability, as team members take ownership and responsibility for their work and outcomes.

Increased commitment, as team members are more engaged and motivated by having a say in how they work.

The other options are not benefits of self-organization, as they may imply external control or pressure.

References: Scrum Guide

According to the Scrum Guide1, the Developers are self-organizing and decide how to turn Product Backlog items into an Increment of value. No one tells them how to do their work. The Developers are accountable for creating a plan for the Sprint, the Sprint Backlog. 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, when the Scrum Team gets caught in an internal disagreement about which development techniques to apply, two techniques that the Scrum Master could use are:

Involve the complete Development Team, as they are responsible for managing and refining their own work.

Use coaching techniques, such as open questions and active listening, to help the Development Team resolve their conflict and reach a consensus.

The other options are not appropriate, as they may undermine the self-organization and empowerment of the Developers.

References: Scrum Guide

The correct answer is C, because the Scrum Guide states that “the Development Team usually starts by designing the system and the work needed to convert the Product Backlog into a working product Increment. Work planned for the first days of the Sprint by the Development Team is decomposed by the end of this meeting, often to units of one day or less. The Development Team self-organizes to undertake the work in the Sprint Backlog, both during Sprint Planning and as needed throughout the Sprint.” Therefore, enough work should be defined during the Sprint Planning event so that the Development Team can create its best forecast of what it can do, and to start the first several days of the Sprint.

According to the Nexus Guide2, which is a framework for scaling Scrum, one way to form multiple Development Teams from a large group of people is to ask them to self-organize into teams based on dependencies, skills, domain knowledge, and personal preferences. This approach respects the autonomy and empowerment of the Developers and allows them to choose how they want to work together.

References: Nexus Guide

According to the Scrum Guide, the purpose of a Sprint is to produce a valuable useful Increment that meets the Definition of Done and the Sprint Goal. This means that the Developers work on items from the Product Backlog that deliver value to the stakeholders and align with the product vision. The other option is not valid, as it implies that producing an Increment is not the purpose of a Sprint.

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).

There are no activities that a Product Owner would typically undertake in the phase between the end of the current Sprint and the start of the next Sprint, because there is no such phase. The next Sprint starts immediately after the current Sprint, without any gaps or breaks. The other options are either activities that occur during a Sprint (such as refining the Product Backlog) or activities that are not consistent with Scrum (such as working with Quality Assurance departments or updating project plans).

 According to the Scrum Guide, changing the terminology of Scrum may have negative consequences, such as losing the benefits of Scrum, not understanding what has changed, or having very little change at all. Therefore, all answers apply to this question. The Scrum Guide recommends using the same terminology as in the guide to avoid confusion and misunderstanding.

According to the Scrum Guide1, one aspect of Scrum Teams inspecting how they work toward their Product Goal is that they improve their definition of “Done” over time. 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. Therefore, it is most appropriate for a Development Team to change the definition of “Done” during the Sprint Retrospective.

The correct answer is A, because keeping component teams while starting Scrum may cause less initial disruption than organizing into new teams. As they start using Scrum, they will discover what works best for them and how to potentially re-organize towards feature teams. However, component teams may face some challenges in delivering a working Increment of software that provides business value every Sprint, as they may depend on other teams or layers.

According to the Scrum framework, the Product Owner is responsible for managing the Product Backlog, which includes prioritizing and adding new items1. However, when a new item is introduced during a Sprint, it is crucial to involve the entire Scrum Team in the decision-making process. This ensures that the team can assess the impact of the new item on the current Sprint goals, capacity, and workload1. By discussing the item with the team, they can collectively decide whether to include it in the current Sprint, defer it to a future Sprint, or handle it in another way1. This collaborative approach aligns with the principles of transparency, inspection, and adaptation, which are core to Scrum.

According to the Scrum Guide, a Development Team is cross-functional if it has all the skills to create a potentially releasable Increment by the end of every Sprint. The other options are not indicators of cross-functionality, as they are either specific practices (such as pair programming or test driven development) or irrelevant factors (such as conflicts within the team or ability to perform every task).

According to the Scrum Guide, when many Scrum Teams are working on a single product, they must have a Definition of Done that makes their combined work potentially releasable. This ensures that there is a clear and consistent understanding of what “Done” means for the product and that there is no technical debt or unfinished work at the end of each Sprint. The other options are not valid descriptions of the Definition of Done for multiple Scrum Teams, as they either create inconsistency, confusion, or waste (such as having different definitions, discussing and reconciling differences during a hardening Sprint, or having the Scrum Masters define a common Definition of Done).

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 answer is D, because if a new Development Team decides that a Sprint Retrospective is unnecessary, the Scrum Master should begin facilitating productive and useful Sprint Retrospectives. The Scrum Guide states that “the purpose of the Sprint Retrospective is to plan ways to increase quality and effectiveness. … During each Sprint Retrospective, the Scrum Team plans ways to improve product quality by adapting the definition of ‘Done’ as appropriate.” Therefore, the Scrum Master should help the Development Team understand the value and importance of the Sprint Retrospective, and make it an engaging and constructive event.

Scrum is not a process, technique, or definitive method. Rather, it is a framework within which you can employ various processes and techniques. Scrum makes clear the relative efficacy of your product management and work techniques so that you can continuously improve the product, the team, and the working environment.

According to the Scrum Guide, the Developers are accountable for managing the progress of work during a Sprint, as they are responsible for creating a valuable Increment that meets the Definition of Done and the Sprint Goal. The other options are not valid, as they imply that the Product Owner, the Scrum Master, or the most junior member of the team are accountable for managing the progress of work, which is not consistent with Scrum.

The Product Owner is responsible for ensuring that the most valuable functionality is produced first, at all times, by ordering and prioritizing the Product Backlog. The Product Owner also interacts with stakeholders to understand their needs and expectations, and to communicate the vision and progress of the product. The other options are not part of the Product Owner role according to Scrum, as they are either too prescriptive or too technical.

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. The Developers are self-organizing and decide how to turn Product Backlog items into an Increment of value. Therefore, the Scrum Master should allow the Development Team to self-manage and determine for itself what to do regarding the logistical challenges of meeting in different locations.

References: Scrum Guide

According to the Scrum Guide, 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 topics that are appropriate for discussion are those that relate to how the team does its work, such as team relations, Definition of Done, and processes, tools, communication, collaboration, quality, etc. The other options are not appropriate topics for discussion in a Sprint Retrospective, as they belong to other Scrum events (such as arranging the Sprint Backlog for the next Sprint in the Sprint Planning or evaluating the value of work in the Product Backlog in the Sprint Review).

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.

The correct answer is B, because multiple Scrum Teams working on the same project do not have to have the same Sprint start date. 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, the synchronization of multiple Scrum Teams is based on their shared product goal and definition of ‘Done’, not on their Sprint start date.

The correct answer is B, because the time-box for a Daily Scrum is 15 minutes. The Scrum Guide states that “the Daily Scrum is a 15-minute time-boxed event for the Development Team to synchronize activities and create a plan for the next 24 hours.”

The best answer is C. When multiple Scrum Teams are working together on a product, they must mutually define and comply with the same Definition of Done. This is because the Definition of Done creates transparency and ensures that the product Increment meets the quality standards required for the product1. If each Scrum Team has its own Definition of Done, it may lead to inconsistencies, conflicts, and technical debt in the product. Therefore, the Scrum Teams should collaborate and agree on a common Definition of Done that applies to all Product Backlog Items and Increments. This way, the Scrum Teams can deliver a potentially releasable product Increment at the end of every Sprint2.

The correct answer is B, because a product Increment does not have to be released to production at the end of each Sprint. The Scrum Guide states that “at the end of a Sprint, the new Increment must be ‘Done,’ which means it must be in useable condition and meet the Scrum Team’s definition of ‘Done’. An increment is a body of inspectable, done work that supports empiricism at the end of the Sprint. The increment is a step toward a vision or goal.” Therefore, a product Increment must be potentially releasable, but the decision to release it is up to the Product Owner.

The correct answer is A, because the Product Owner does not need to be present at the Daily Scrum. The Scrum Guide states that “the Daily Scrum is a 15-minute time-boxed event for the Development Team to synchronize activities and create a plan for the next 24 hours. … The structure of the meeting is set by the Development Team and can be conducted in different ways if it focuses on progress toward the Sprint Goal.” Therefore, the Daily Scrum is an internal event for the Development Team, and the Product Owner can attend only if invited by the Development Team.

According to the Scrum Guide1, during each Daily Scrum, each Developer answers three questions:

What did I do yesterday that helped meet our Sprint Goal?

What will I do today to help meet our Sprint Goal?

Do I see any impediment that prevents me or our Development Team from meeting our Sprint Goal?

The Developers can select whatever structure and techniques they want, as long as their Daily Scrum focuses on progress toward achieving their Sprint Goal and producing a usable Increment. The Developers can start with any one person and proceed in any order.

References: Scrum Guide

A Developer is accountable for creating a plan for the Sprint, the Sprint Backlog, and organizing the work required to meet the Sprint Goal, as stated in the Scrum Guide: "Developers are the people in the Scrum Team that are committed to creating any aspect of a usable Increment each Sprint. The specific skills needed by the Developers are often broad and will vary with the domain of work. However, the Developers are always accountable for:

Creating a plan for the Sprint, the Sprint Backlog;

Instilling quality by adhering to a Definition of Done;

Adapting their plan each day toward the Sprint Goal; and,

Holding each other accountable as professionals."

According to the Scrum Guide, a Scrum Master fulfills a different role from a traditional project manager. A Scrum Master is a servant-leader and a coach for the Scrum Team and the organization, not a manager or a supervisor. A Scrum Master does not assign tasks, set deadlines, or monitor progress, but rather facilitates self-organization, collaboration, and empiricism within the Scrum Team and the organization.

According to the Scrum Guide1, Product Backlog refinement is an ongoing activity in which Product Backlog items are reviewed and revised. The Developers who will be doing the work are responsible for sizing or estimating it. The Product Owner may influence them by helping them understand and select trade-offs.

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.”

According to the Scrum Guide, a Scrum Team is cross-functional if it includes skilled individuals who together have all the skills necessary to create value each 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 cross-functionality, as they either imply that the Developers work in silos or rely on external people (such as business analysts, architects, testers, or separate teams).

According to the Scrum Guide, the Product Backlog is an ordered list of everything that is known to be needed in the product. It is allowed to grow and change as more is learned about the product and its customers. The other options are not accurate descriptions of the Product Backlog, as they are either too restrictive (such as providing just enough information or baselining to follow change management processes) or too comprehensive (such as containing all foreseeable tasks and requirements or enabling a complete project plan).

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 Guide, estimates are made by the people doing the work, which is the Development Team. The Development Team is responsible for all estimates in the Product Backlog and the Sprint Backlog. The other options are not valid guidelines for estimating work in Scrum, as they are either too prescriptive (such as requiring story points or relative units), incorrect (such as forbidding estimating or having the Product Owner make estimates), or unnecessary (such as checking estimates with the Development Team).

The best answer is B. A valuable, useful Increment that meets the Definition of Done.

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, the Increment must be usable.” The Scrum Guide also states that “work cannot be considered part of an Increment unless it meets the Definition of Done. The Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product.”

Therefore, a Scrum Team should deliver a valuable, useful Increment that meets the Definition of Done at the end of each Sprint. This ensures that the product is potentially releasable and that the stakeholders can inspect and provide feedback on it.

A, C, and D are not correct answers.

A. A single document, if that is what management asked for.

This answer does not reflect the Scrum values of commitment, focus, and respect1. A Scrum Team should not deliver a single document just because management asked for it, but rather deliver an Increment that provides value to the customers and users. A document may be part of an Increment, but it is not an Increment by itself.

C. Failing unit tests, to identify acceptance tests for the next Sprint.

This answer does not reflect the Scrum principle of empiricism1. A Scrum Team should not deliver failing unit tests, but rather deliver an Increment that is thoroughly verified and meets the quality standards. Failing unit tests indicate that the work is not done and that there are defects or errors in the product. A Scrum Team should use unit tests to ensure that the product works as expected and to identify and fix any issues before delivering the Increment.

D. An Increment of software with minor known bugs in it.

This answer does not reflect the Scrum value of openness1. A Scrum Team should not deliver an Increment of software with minor known bugs in it, but rather deliver an Increment that meets the Definition of Done and is free of any known defects or issues. Delivering an Increment with bugs in it can compromise the trust and satisfaction of the stakeholders and can lead to technical debt or rework in the future. A Scrum Team should strive to deliver high-quality products that meet or exceed the expectations of the customers and users.

According to the Scrum Guide1, the Sprint Backlog is the property of the Developers and no one else can tell them which items they should work on. The Developers can select any item from the Product Backlog that they forecast they can complete within a Sprint. The Developers are self-organizing and decide how to turn Product Backlog items into an Increment of value. Therefore, no one owns a Sprint Backlog item, but the entire Development Team is accountable for it.

References: Scrum Guide

According to the Scrum Guide, the Development Team is responsible for creating a “Done” Increment that meets the Definition of “Done”. User documentation is part of the Definition of “Done” in this scenario, so the Development Team must create it. The other options are not consistent with Scrum values and principles, such as self-organization, cross-functionality, and empiricism.

The correct answers are B and D, because the Scrum Guide states that “the number of items selected from the Product Backlog for the Sprint is solely up to the Development Team. Only the Development Team can assess what it can accomplish over the upcoming Sprint.” Therefore, the Development Team can remove or change selected Product Backlog items in agreement with the Product Owner if they see that the workload is greater than they can handle. The Development Team should also ensure that the Product Owner is aware of the situation, start the Sprint, and monitor progress.

The product has one Product Backlog, as it is a single source of requirements for any changes to be made to the product. There should be only one Product Owner, who is accountable for maximizing the value of the product and the work of the Development Team. Having multiple Product Owners or Product Backlogs would create confusion, inconsistency, and waste.

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.

The correct answer is B. The Scrum Team includes skilled individuals who together have all the skills necessary to create value each Sprint. According to the Scrum Guide1, “Scrum Teams are cross-functional, meaning the members have all the skills necessary to create value in each Sprint.” This does not mean that every individual has all the skills, but rather that the team as a whole does. Cross-functionality enables the Scrum Team to deliver a potentially releasable Increment of “Done” product at the end of each Sprint, without depending on others outside the team.

The correct answer is A, because the role of management in Scrum is to facilitate the Scrum Teams with insights and resources that help them improve. The Scrum Guide states that “the organization respects their self-organization by not telling them how they should do their work.” Therefore, management should support the Scrum Teams by providing them with an environment that fosters collaboration, learning, and innovation.

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 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 Guide, the Product Owner can cancel a Sprint, 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.

The correct answer is A, because the best way the Scrum Master can ensure that the Development Team communicates effectively with the Product Owner is to monitor communications between them and facilitate direct collaboration. The Scrum Guide states that “the Scrum Master serves the Product Owner in several ways, including … facilitating Scrum events as requested or needed.” Therefore, the Scrum Master should help the Development Team and the Product Owner interact regularly and productively during the Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective events.

If the Development Team cannot complete its work by the end of the Sprint, then the Sprint length holds and the Development Team continuously learns what is actually possible to do within a Sprint of this length, as stated in [7]: “If a Development Team determines it has overcommitted itself for a Sprint, one option is to collaborate with the Product Owner to negotiate removing or reducing scope. Another option is to simply work hard and do its best, without cutting quality or pressuring individuals. In either case, the Development Team learns from its experience and uses this learning when planning future Sprints.”
