PSM-I Professional Scrum Master I Questions and Answers

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 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 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 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 other roles are not responsible for making sure everyone on the Development Team does their tasks for the Sprint.

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 of “Done” is created by the development organization (or Development Team if none is available from the development organization). The definition guides the Development Team in creating a “Done” Increment.

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 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).

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 correct answers are B and E, because these statements are true about the length of the Sprint. It is best to have Sprints of consistent length throughout a development effort, as this helps establish a reliable rhythm and cadence for the Scrum Team and the stakeholders. All Sprints must be one month or less, as this ensures that the Scrum Team can inspect and adapt frequently and deliver value incrementally.

According to the Scrum Guide1, the Product Backlog is an ordered list of everything that is known to be needed in the product. It is the single source of requirements for any changes to be made to the product. The Product Owner is accountable for maximizing value resulting from work by Developers. The Product Owner is also accountable for effective Product Backlog management, which includes:

• Developing and explicitly communicating the Product Goal;
• Creating and clearly communicating Product Backlog items;
• Ordering Product Backlog items; and
• Ensuring that the Product Backlog is transparent, visible and understood.

Therefore, the Product Owner is responsible for clearly expressing Product Backlog items.

According to the Scrum Guide1, the Sprint Review is an informal meeting at the end of the Sprint, where the Scrum Team and stakeholders collaborate about what was done in the Sprint. Based on that and any changes to the Product Backlog during the Sprint, attendees collaborate on what to do next. The Product Owner explains what Product Backlog items have been “Done” and what has not been “Done”; the Development Team discusses what went well during the Sprint, what problems it ran into, and how those problems were solved; and the Development Team demonstrates the work that it has “Done” and answers questions about the Increment. The entire group collaborates on what to do next, so that the Sprint Review provides valuable input to subsequent Sprint Planning. The Sprint Review is mainly an inspect and adapt opportunity for the Scrum Team and stakeholders.

References: Scrum Guide

The correct answer is B, because when multiple teams work together on the same product, they should not maintain separate Product Backlogs. 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. … Multiple Scrum Teams working on the same product use the same Product Backlog.”

Architecture and infrastructure are handled in Scrum by implementing them along with functional development of the product, and by adding them to the Product Backlog and addressing them in early Sprints, while always requiring at least some business functionality, no matter how small, as stated in [2]: “Scrum does not distinguish between developing functionality or architecture. They are developed together, as they are both important and support each other. Architecture is not a separate phase; it is part of the product development. Architecture is added to the Product Backlog as any other feature or functionality.”

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.

According to the Scrum Guide, the Product Owner has the final say on the order of 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.

The correct answer is F, because all of the Scrum Values are affected by a lack of trust in the Scrum Team. Trust is essential for the Scrum Team to work effectively and deliver value. Without trust, the Scrum Team may lose focus, respect, openness, courage, and commitment.

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, 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 Product Owner is responsible for maximizing the value of the work the Development Team does.

References: Scrum Guide

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.

According to the Scrum Guide, multiple Scrum Teams working on the same product do not have to have the same Sprint start date. They may start their Sprints at different times, as long as they synchronize their work and integrate their Increments at least by the end of each Sprint. The other option is not valid, as it implies that having the same Sprint start date is mandatory for multiple Scrum Teams.

The correct answers are C and E, because these statements explain what “Done” means. No work left from the definition of “Done” means that all Product Backlog items selected for a Sprint meet the quality criteria agreed upon by the Scrum Team. All work to create software that is ready to be released to end users means that the Increment is potentially releasable at any time during the Sprint.

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, 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

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).

he correct answer is A, because doing all work needed to meet the definition of “Done” enhances the transparency of an increment. The Scrum Guide states that “when a Product Backlog item or an Increment is described as ‘Done’, everyone must understand what ‘Done’ means.” Therefore, by meeting the definition of “Done”, an increment becomes transparent to all stakeholders and ready for release.

According to the Scrum Guide1, 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. The 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.

References: Scrum Guide

According to the Scrum Guide1, each Sprint is a project with no more than a one-month horizon. The Sprint Goal gives guidance to why the Scrum Team is building an Increment. 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. Therefore, in the first Sprint, as in any other Sprint, the Development Team should develop at least one piece of functionality and create an increment of potentially releasable software. The other options are not consistent with Scrum values and principles.

References: Scrum Guide

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 Review is a time for the Scrum Team and the stakeholders to inspect the product Increment and adapt the Product Backlog if needed. The Product Owner is responsible for keeping the stakeholders aware of the progress of the project and inviting them to the Sprint Review. If the Product Owner has not been doing this, or if the stakeholders have not been using the Sprint Review to inspect and evaluate progress, then they may be disappointed and angry at the seventh Sprint Review. The other options are not likely factors that led to this situation, as they are either irrelevant (such as the PMO or the development area) or incorrect (such as delaying the release).

According to the Scrum Guide, two characteristics of the Daily Scrum are its location and time remain constant and its purpose is to inspect progress toward the Sprint Goal and adapt the Sprint Backlog. These characteristics promote consistency, transparency, and adaptation within the Development Team. The other options are not valid characteristics of the Daily Scrum, as they are either irrelevant (such as being held first thing in the morning) or inappropriate (such as being free form, facilitated by the team lead, or consisting of the Scrum Master asking for status).

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 correct answer is B, because the Development Team determines how work is performed during the Sprint. 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, the Development Team has the autonomy and responsibility to organize and manage its own work.

The correct answer is C. The Scrum Team creates the Definition of Done. According to the Scrum Guide1, “The Developers are required to conform to the Definition of Done, which is defined and evolves with the Scrum Team.” The Definition of Done is a commitment by the Developers for the Increment, but it is also a shared understanding within the whole Scrum Team, including the Product Owner and the Scrum Master2. The Scrum Team collaborates to create and update the Definition of Done as needed, based on the product and organizational standards3. The Definition of Done is not imposed by any external authority or individual.

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).

The correct answers are B and E, because Scrum has no “tester” role and everyone in the Development Team is responsible for quality. 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. The resulting synergy optimizes the Development Team’s overall efficiency and effectiveness.”

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, 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).

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, when multiple Scrum Teams are working together on one product, they must coordinate their work with each other. One way to do this is through Nexus, a framework for scaling Scrum. Nexus helps to reduce cross-team dependencies and integration issues by making them more transparent. The key concern when multiple Development Teams are working from the same Product Backlog is minimizing dependencies between teams so that they can deliver an integrated Increment that meets the definition of “Done”.

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).

 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 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.”

The correct answers are D and E, because these are two activities that a Product Owner can engage in during a Sprint. The Scrum Guide states that “the Product Owner is responsible for maximizing the value of the product resulting from work of the Development Team.” Therefore, the Product Owner can answer questions from the Development Team about items in the current Sprint, and work with the stakeholders to understand their needs and expectations.

The correct answer is A. When multiple Scrum Teams are working together on a product, they must mutually define and comply with the same Definition of Done. According to the Scrum Guide1, “If there are multiple Scrum Teams working on the system or product release, the development teams on all of the Scrum Teams must mutually define the definition of “Done”.” This ensures that the product increment is integrated, consistent, and potentially releasable at the end of each Sprint. The other options are incorrect because they allow for different Definitions of Done for different teams, which can lead to confusion, inconsistency, and technical debt.

According to the Scrum Guide, the Developers on the Scrum Team should write the user documentation, as they are responsible for creating a “Done” Increment that meets the Definition of Done and the Sprint Goal. The other options are not valid, as they imply that the user documentation can be deferred, ignored, or outsourced, which is not consistent with Scrum values and principles.

A Developer becomes accountable for an item in the Sprint Backlog never as Developers on the Scrum Team share accountability for items in the Sprint Backlog, as stated in the Scrum Guide: “The Developers can select whatever items they want as long as they feel they can complete the work by the end of the Sprint. The Scrum Team is responsible for all estimates. The Product Owner may influence the Developers by helping them understand and select trade-offs, but the people who will perform the work make the final estimate.”

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 Scrum Master and Product Owner may attend as observers, but only if it is useful for the Developers.

The best answer is C. The function or purpose of management in Scrum is to present the Scrum Teams with insights and resources that help them improve. According to the article What is the Function or Purpose of Management in Scrum?, management is still critical to providing vision, securing resources, hiring talent, training teams, removing roadblocks, and continuously improving. Management also encourages collaboration and establishes Scrum Team autonomy, which are essential for Scrum’s values and principles.

A, B and D are not good answers because they imply a command-and-control approach that contradicts Scrum’s values of respect, openness, and self-organization. Management in Scrum is not supposed to micromanage, judge, or interfere with the work of the Developers, but rather support them and enable them to deliver value.

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 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. A project manager is not part of the Scrum Team, as Scrum does not recognize titles or sub-teams. None of the above is also not a correct answer, as it implies that there is no Scrum Team at all.

 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 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 best two answers are A and B. As a Scrum Team, prioritizing the list and working on them in order is a good technique to tackle the impediments. This way, the team can focus on the most urgent and important issues first and avoid being overwhelmed by the number of impediments. The Scrum Master discusses the impediments with the Scrum Team is also a helpful technique, as it allows the team to share their perspectives, identify the root causes, and come up with possible solutions. The Scrum Master can also coach the team on how to remove or prevent impediments in the future.

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 other options are not relevant or appropriate for the Daily Scrum.

References: Scrum Guide

The correct answer is D, because the Scrum Guide states that “a Sprint is a container for all other events. 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.” Therefore, a Sprint is over when its time-box expires, regardless of whether all Product Backlog items or tasks are completed or not.

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.

References: Scrum Guide

According to the Scrum Guide1, one aspect of Scrum Teams inspecting how they work toward their Product Goal is that they create a Sprint Goal every Sprint. 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 Developers on why it is building the Increment. It also provides a basis for inspecting and adapting during the Sprint Review and Sprint Retrospective. The Sprint Goal is created during the Sprint Planning event.

References: Scrum Guide

According to the Scrum Guide, a Developer becomes accountable for the value of a Product Backlog item selected for the Sprint at the Sprint Planning event. This is when the Developers select items from the Product Backlog that they can commit to complete within a Sprint. The Developers are then responsible for creating a valuable Increment that meets the Definition of Done and the Sprint Goal. The other options are not valid, as they either imply that Developers are not accountable for value (such as never or whenever), or that they become accountable at a different time (such as during the Daily Scrum).

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 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 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.

 According to the Scrum Guide1, 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.

The correct answer is E, because all of these topics can be discussed during a Sprint Retrospective. 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 Team can discuss any aspect of their process, communication, skills, or definition of ‘Done’ that may help them improve.

The correct answer is B, because the Scrum Guide states that “the Development Team modifies the Sprint Backlog throughout the Sprint, and the Sprint Backlog emerges during the Sprint. This emergence occurs as the Development Team works through the plan and learns more about the work needed to achieve the Sprint Goal.” Therefore, new work or further decomposition of work can be added to the Sprint Backlog as soon as possible after they are identified by the Development Team.

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.

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.

References: Scrum Guide

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 best answer is B. The need for the team to learn based on doing work and measuring results.

The Sprint length should be chosen based on the complexity and volatility of the product and the environment, as well as the team’s capability and Definition of Done. The Sprint length should enable the team to deliver a usable Increment of value that meets the feedback needs of the stakeholders and the business. The Sprint length should also allow the team to inspect and adapt their work processes and practices based on the outcomes of the Sprint.

The other options are not valid reasons for choosing the Sprint length. The organization’s mandate, team formation, and release schedule should not dictate the Sprint length, but rather be aligned with it. The Scrum Team should have the autonomy to choose the Sprint length that best suits their product and context.

You can learn more about how to choose the right Sprint length from these sources: How Long A Sprint Should Be?, How to Choose the Right Sprint Length in Scrum, What is a Sprint?, Determining the Sprint Length, and Sprint Length: What’s the Right Length?.

According to the Scrum Guide, management external to the Scrum Team is not involved in the Daily Scrum at all. The Daily Scrum is an internal event for the Development Team to inspect their progress toward the Sprint Goal and plan their work for the next 24 hours. The other options are not valid ways for management to be involved in the Daily Scrum, as they are either intrusive (such as giving an update or speaking on behalf of others) or unnecessary (such as being represented by the Product Owner or the Scrum Master).

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.
