PSPO-I Questions and Answers

 The Product Owner must spend enough time with the Developers so that they are confident the Increment will meet the intended value. This is because:

• The Developers are accountable for creating a “Done” Increment in every Sprint. They must ensure that every Product Backlog item they work on meets the Definition of Done before it is considered complete.
• The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. They must inspect the Increment at the end of each Sprint and assess how it delivers value and contributes to the Product Goal.
• The Product Owner and the Developers must collaborate closely throughout the Sprint to ensure that they have a shared understanding of what they are building and why. The Product Owner must provide clarifications, feedback, and guidance to the Developers as needed to help them create a valuable Increment.
• The amount of time that the Product Owner must spend with the Developers may vary depending on the context, complexity, and uncertainty of the product development. However, it should be enough so that both parties are confident that the Increment will meet the intended value.

Other options, such as 40%, as much time as the Developers tell them to be present, or 100%, are not valid answers as they imply a fixed or arbitrary amount of time that does not reflect the actual needs and dynamics of the product development.

The Daily Scrum is an event for and by the Developers. They can choose whatever structure and technique they want, as long as they focus on the progress toward the Sprint Goal and produce an actionable plan for the next day of work12. The Scrum Master, the Product Owner, and the person coming in last are not necessarily the ones who should start the Daily Scrum. The person who has the token is a possible technique, but not the only one3.

The Sprint Goal is a short statement that gives the Sprint a purpose, direction, and focus. It is created by the entire Scrum Team during Sprint Planning, based on the Product Owner’s draft and the Developers’ input. The Sprint Goal is then added to the Sprint Backlog and guides the Developers’ work during the Sprint.

• The Sprint Review is an event that occurs at the end of each Sprint, where the Scrum Team and the stakeholders inspect the Increment and adapt the Product Backlog if needed. The Sprint Review is an opportunity for the Product Owner to validate that the Increment meets their expectations and delivers value to the customers and users. The Sprint Review is also an opportunity for the Developers to demonstrate their work and receive feedback from the Product Owner and the stakeholders.
• The purpose of a Sprint Review is to inspect the product Increment with the stakeholders and collect feedback on next steps. The Sprint Review is a collaborative and interactive session where the Scrum Team and the stakeholders discuss what was done in the Sprint, what problems were encountered, what was learned, and what can be improved or changed. The Sprint Review also provides input for updating the Product Backlog to maximize value in future Sprints.
• The other options are not valid or relevant purposes of a Sprint Review. They are either too vague, unrelated, or incorrect. They are:

The Scrum Master is a servant-leader for the Scrum Team, who helps the team understand and enact Scrum values, principles, and practices1. The Scrum Master also facilitates Scrum events as requested or needed2. The Daily Scrum is a 15-minute event for the Developers to inspect their progress toward the Sprint Goal and adapt the Sprint Backlog as necessary[3][3]. It is a key opportunity for the Developers to plan their work for the next 24 hours and collaborate on any challenges or impediments4. The Scrum Master should coach the team on the purpose and value of the Daily Scrum, and help them find ways to make it more effective and enjoyable. The Scrum Master should also learn why the Developers want to reduce the frequency of the Daily Scrum, and work with them to address any underlying issues or concerns. The Scrum Master should not impose a decision on the team, nor delegate the decision to a vote, as these actions would undermine the self-management and empowerment of the Developers5.

The ideal time for refinement to take place and who should participate are the Scrum Team during the current Sprint, if they have been unable during preceding Sprints to define Product Backlog items with enough precision to begin work, and the Scrum Team on an ongoing basis, defining Product Backlog items into smaller more precise items that are ready for selection. This is because:

• Product Backlog refinement is the act of adding detail, estimates, and order to Product Backlog items. It is an ongoing and collaborative process that involves the whole Scrum Team.
• The Scrum Team should refine the Product Backlog as needed to ensure that there are enough items that are sufficiently clear and ready for selection in Sprint Planning. The amount of time spent on refinement usually varies from one Scrum Team to another, but it is recommended not to exceed 10% of the capacity of the Developers.
• The Scrum Team may also use a Sprint to refine the Product Backlog if they have not been able to do so in previous Sprints. This may happen when the product is new or complex, or when there is a significant change in the product vision or direction. However, this should be an exception rather than a rule, as it may delay the delivery of value and feedback.

Other options, such as business analysts doing the refinement work for the Scrum Team, the Product Owner doing the refinement alone in Sprint 0 or between Sprints, or handing off the ownership of the Product Backlog to someone else, are not consistent with the principles and values of Scrum. They may lead to misunderstandings, misalignment, or loss of ownership and accountability.

The Sprint Retrospective is one of the five events defined by Scrum. It is a formal opportunity for the Scrum Team to inspect itself and create a plan for improvements to be enacted during the next Sprint. The purpose of the Sprint Retrospective is to adapt the way of working so that it becomes more effective and enjoyable. The other options are not required by Scrum, but may be useful practices depending on the context. Developers do not have to stand up at the Daily Scrum, they can choose any format that works for them. A Sprint Burndown Chart is a common way to visualize the remaining work in a Sprint, but it is not mandated by Scrum. Release Planning is a topic that falls under the broader competency of Managing Products with Agility, but it is not a prescribed event in Scrum.

During the Sprint Review, the stakeholder’s role is not to reorder the Product Backlog, but rather to provide feedback and suggestions on the product and the process. Therefore, the answer is false because:

• The Sprint Review is an informal meeting, not a status meeting, and the presentation of the Increment is intended to elicit feedback and foster collaboration. The stakeholders are invited to attend the Sprint Review as observers, participants, or customers, and they can share their opinions, ideas, or requests regarding the product and its features, functionality, quality, value, etc.
• The ordering of the Product Backlog is the sole responsibility of the Product Owner. They order Product Backlog items to best achieve goals and missions. The Product Owner may consider the feedback and suggestions from the stakeholders, as well as other factors such as dependencies, risks, costs, etc., when ordering the Product Backlog. However, they are not obliged to follow or implement them.
• The Product Backlog is not a fixed or final list of requirements, but rather an emergent and dynamic artifact that represents all the possible changes to the product. The Product Owner is accountable for effective Product Backlog management, which includes refining, communicating, and optimizing the Product Backlog items. The Product Owner may update the Product Backlog at any time, not only during the Sprint Review.

A Product Owner is accountable for maximizing the value of the product that is the result of the work of the Scrum Team. However, they can delegate some of their responsibilities to others, while still remaining accountable for the work. Two of the responsibilities that can be delegated to others are:

• Attending the Sprint Retrospective. The Sprint Retrospective is an event where the Scrum Team inspects how the last Sprint went with regards to individuals, interactions, processes, tools, and their Definition of Done. The purpose of the Sprint Retrospective is to plan ways to improve quality and effectiveness. The Product Owner may attend the Sprint Retrospective as one of the Scrum Team members who has a stake in the outcome of the product development. However, they can also choose not to attend or delegate their attendance to someone else who can represent their interests and perspectives.
• Attending the Sprint Review. The Sprint Review is an event where the Scrum Team and stakeholders inspect the Increment and adapt the Product Backlog if needed. The purpose of the Sprint Review is to elicit feedback and foster collaboration. The Product Owner is accountable for ensuring that key stakeholders attend the Sprint Review and that they understand what has been done and what can be done next. However, they can also delegate some of their tasks to others who can facilitate or present the Increment on their behalf.

Other options, such as ordering Product Backlog items or developing and communicating the Product Goal, are not responsibilities that can be delegated to others by the Product Owner. They are essential accountabilities that only the Product Owner can perform.

The Scrum Master should talk to the IT manager and explain that progress in Scrum comes from inspecting an Increment at the Sprint Review. This is because:

• The Scrum Team is self-managing and does not need to report to anyone outside the team1.
• The Sprint Review is an event where the Scrum Team and the stakeholders collaborate on the product and inspect the Increment2.
• The Increment is a concrete and usable outcome of the Sprint that provides a measure of progress and value delivery3.
• The IT manager can attend the Sprint Review as a stakeholder and provide feedback on the product and the process4.

• The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. The Product Owner is responsible for managing and refining the Product Backlog, collaborating with the stakeholders and the Developers, and ordering the items in a way that best achieves goals and missions. The Product Owner represents the interests of everyone with a stake in the product and ensures that the Scrum Team works on the right things at the right time.
• A Sprint is a timebox of one month or less within which a “Done” product Increment is created. A Sprint consists of the Sprint Planning, Daily Scrums, the development work, the Sprint Review, and the Sprint Retrospective. A Sprint is also a feedback loop that allows the Scrum Team and the stakeholders to inspect and adapt the product and the process.

The best approach for Scrum Teams to produce valuable Increments is to be accountable for developing functionality from beginning to end, as this enables them to deliver potentially releasable products that meet the definition of “Done”. The Scrum Guide states that "The Developers are the people in the Scrum Team that are committed to creating any aspect of a usable Increment each Sprint."1 This means that the Developers are not limited by the boundaries of components, layers, or technologies, but rather they collaborate and coordinate to deliver a complete and integrated product that satisfies the Sprint Goal and the Product Owner’s expectations.

The following are true about Scrum:

• Scrum is based on empiricism and lean thinking. Empiricism is the principle of making decisions based on what is observed and experienced, rather than on theory or speculation. Lean thinking is the philosophy of eliminating waste and maximizing value in any process or system. Scrum applies these concepts by providing a framework for inspecting and adapting the product and the process, and by focusing on delivering the most valuable features to the customers and stakeholders.
• Scrum is a framework for developing and sustaining complex products. A complex product is one that has unpredictable or unknown aspects that require creativity, experimentation, and adaptation to deliver. A framework is a set of minimal and essential rules and roles that provide structure and guidance, but leave room for flexibility and innovation. Scrum provides such a framework for teams to collaborate and deliver complex products iteratively and incrementally, while embracing change and feedback.
• 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 consists of three roles (Product Owner, Scrum Master, Developers), five events (Sprint, Sprint Planning, Daily Scrum, Sprint Review, Sprint Retrospective), and three artifacts (Product Backlog, Sprint Backlog, Increment). Each of these components has a clear definition, accountability, and goal that contributes to the overall effectiveness and value of Scrum. Removing or changing any of these components may cause the benefits of Scrum to be lost or diminished.

• Scrum Guide 2020, page 3: “Scrum is founded on empiricism and lean thinking.”
• Scrum Guide 2020, page 3: “Scrum is a lightweight framework that helps people, teams and organizations generate value through adaptive solutions for complex problems.”
• Scrum Guide 2020, page 4: “Each component within the framework serves a specific purpose and is essential to Scrum’s success and usage.”

A Product Backlog is:

• Managed by the Product Owner. The Product Owner is the sole person responsible for managing the Product Backlog, which is an emergent, ordered list of what is needed to improve the product. They must ensure that the Product Backlog is transparent, visible, and understood by everyone who needs to work on it.
• An inventory of things to be done for the Product. The Product Backlog contains all the features, functions, requirements, enhancements, and fixes that constitute the changes to be made to the product in future releases. The Product Backlog items have a description, an order, an estimate, and a value.
• Ordered based on priority, value, dependencies, and risk. The Product Owner orders the Product Backlog items based on various factors that affect their importance and urgency for the product. These may include customer needs, business value, stakeholder feedback, technical dependencies, or market opportunities.

Other options, such as an exhaustive list of upfront approved requirements to be implemented or only visible to the Product Owner and stakeholders, are not valid descriptions of a Product Backlog. They may reflect a misunderstanding of what a Product Backlog is or how Scrum works.

• The Scrum Team is a self-organizing and cross-functional team that delivers valuable products in an agile way. The Scrum Team consists of one Product Owner, one Scrum Master, and Developers. They are all accountable for creating a valuable, useful, and potentially releasable product Increment each Sprint.
• An Increment is a concrete stepping stone toward the product vision. It is the sum of all the Product Backlog items completed during a Sprint and the value of the increments of all previous Sprints. At the end of a Sprint, the new Increment must be “Done”, which means it meets the Definition of Done and is usable.
• The Scrum Team is accountable for creating a valuable increment every Sprint, not just once or occasionally. This means that the Scrum Team must deliver a product functionality that provides value to the customers and users and contributes to the product goals and missions. The value of an increment can be measured by various factors, such as customer satisfaction, feedback, revenue, market share, or social impact.
• The Scrum Team is also accountable for creating a valuable increment every Sprint, not just any increment. This means that the Scrum Team must deliver a product functionality that meets the quality standards and expectations of the customers and users and complies with the Definition of Done. The quality of an increment can be measured by various factors, such as usability, reliability, performance, security, or maintainability.

If a stakeholder is unhappy with the quality of the product, the Scrum Master can coach the Product Owner on how to effectively communicate this concern to the Developers1. The Scrum Master can also encourage the Product Owner to put quality specifications on the Product Backlog1. This allows the Developers to understand the stakeholder’s expectations and work towards meeting them1. The Developers are responsible for building quality into the product, but the stakeholders (through the Product Owner) are responsible for setting what is expected in terms of product and process quality1.

• The length of a Sprint is the timebox within which the Scrum Team creates a potentially releasable product Increment. The Sprint is a container for all the other Scrum events, such as the Sprint Planning, the Daily Scrum, the Sprint Review, and the Sprint Retrospective. The Sprint is also a feedback loop that allows the Scrum Team and the stakeholders to inspect and adapt the product and the process.
• The length of a Sprint should be no more than one calendar month. This is the maximum duration allowed by Scrum, as longer Sprints can increase the complexity and risk of the product development. Longer Sprints can also reduce the agility and responsiveness of the Scrum Team to changing customer needs and market conditions.
• The length of a Sprint should also be short enough to keep the business risk acceptable to the Product Owner. The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. The Product Owner is responsible for managing and refining the Product Backlog, collaborating with the stakeholders and the Developers, and ordering the items in a way that best achieves goals and missions. The Product Owner represents the interests of everyone with a stake in the product and ensures that the Scrum Team works on the right things at the right time. The length of a Sprint affects how frequently and effectively the Product Owner can validate, verify, and deliver value to the customers and users.
• The length of a Sprint should also be short enough to be able to synchronize the development work with other business events. The Scrum Team operates within a broader organizational context that may have other events, cycles, or deadlines that affect or depend on product development. For example, there may be marketing campaigns, sales promotions, regulatory compliance, or contractual obligations that require coordination and alignment with the product delivery. The length of a Sprint affects how well and timely the Scrum Team can synchronize their work with these other business events.

Correct Answer: True

Explanation: Dependencies are relationships between Product Backlog items that affect their order of implementation. For example, a Product Backlog item may depend on another one to be completed first, or it may have a dependency on a third-party system or resource. Dependencies could influence how the Product Owner orders Product Backlog items, as they may introduce risks, constraints, or uncertainties that affect the value delivery. The Product Owner should try to minimize dependencies and order the Product Backlog items in a way that maximizes value and minimizes waste.

• [Professional Scrum Product Owner], chapter 6: “Dependencies are relationships between Product Backlog items that affect their order of implementation.”
• [Managing Dependencies on Agile Projects]: “Dependencies can have a significant impact on the delivery of value.”

The Sprint Retrospective is a time-boxed event for the Scrum Team to inspect how the last Sprint went and plan for improvements in the next Sprint. The Scrum Guide states that "The Sprint Retrospective concludes the Sprint. It is timeboxed to a maximum of three hours for a one-month Sprint. For shorter Sprints, the event is usually shorter."1 This means that the Sprint Retrospective should be held at the end of each Sprint, regardless of the project or release status. The Sprint Retrospective is an opportunity for the Scrum Team to inspect itself and create a plan for improvements, including to product quality and working relationships.1

References:

• 1: The Scrum Guide2, page 16
• 2: The Scrum Guide

 The timebox for the Sprint Review is four hours for a one-month Sprint. This is because:

• The Sprint Review is an event where the Scrum Team and stakeholders inspect the Increment and adapt the Product Backlog if needed. The purpose of the Sprint Review is to elicit feedback and foster collaboration.
• The timebox for each Scrum event is proportional to its frequency and duration. A one-month Sprint corresponds to a maximum calendar month.
• The timebox for a one-month Sprint Review is four hours. For shorter Sprints, it is usually shorter.
• The timebox ensures that there is enough time to inspect what has been done in relation to what could be done next and make any necessary adaptations to optimize value.

Other options, such as two hours for a one-month Sprint, one day, or as long as needed, are not valid answers as they do not reflect the correct timebox for the Sprint Review.

• [Scrum Guide], page 9, section “Sprint”
• [Scrum Guide], page 9, section “Timeboxing Scrum Events”

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."1 The Daily Scrum is a quick and simple planning meeting designed to keep everyone in the loop with how other team members are getting on. It ensures that team members are fully aligned with each other and on track to hit the Sprint Goal.

Correct Answer: D. Never. The entire Scrum Team is accountable for creating value every Sprint.

Explanation: According to the Scrum Guide, the Scrum Team consists of one Product Owner, one Scrum Master, and Developers. The Scrum Team is responsible for all product-related activities, including delivering a valuable, usable product increment every Sprint. The Product Owner is accountable for maximizing the value of the product and the work of the Developers. The Developers are accountable for creating a plan for the Sprint, the Sprint Backlog; instilling quality by adhering to a Definition of Done; and adapting their plan each day toward the Sprint Goal. The Scrum Master is accountable for establishing Scrum as defined in the Scrum Guide, helping everyone understand Scrum theory and practice, and removing impediments to the Scrum Team’s progress.

Therefore, the Developers are not individually accountable for the value of a Product Backlog item selected for the Sprint, but collectively accountable as part of the Scrum Team. The value of a Product Backlog item is determined by the Product Owner, who orders the Product Backlog items based on stakeholder needs and feedback. The Developers collaborate with the Product Owner to understand the value and requirements of each Product Backlog item and deliver a potentially releasable product increment that meets the Definition of Done and the Sprint Goal.

References:

• [Scrum Guide], section 2.2: “The Scrum Team is responsible for all product-related activities from stakeholder collaboration, verification, maintenance, operation, experimentation, research and development, and anything else that might be required.”
• Accountabilities in Scrum | Scrum.org: “Scrum has three accountabilities, each with a different focus : Product Owner (green figure) The "What". With a focus on Value, time to market, return on investment and Total Cost of Ownership (TCO). Developers (red figures) The "How". Focus on building something that is Done – that the increment is useable and potentially releasable.”
• What is a Developer in Scrum? | Scrum.org: “The specific skills needed by the Developers are often broad and will vary based on the type of work they are doing. 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”

The typical size for a Scrum Team is 10 or fewer people, including the Product Owner, the Scrum Master, and the Developers. The Scrum Guide states that "The Scrum Team is small enough to remain nimble and large enough to complete significant work within a Sprint. Fewer than three people decrease interaction and results in smaller productivity gains. Having more than ten people requires too much coordination. Large teams generate too much complexity for an empirical process to be useful."1 This means that the optimal Scrum Team size is between 3 and 10 people, depending on the context and the nature of the work.

References:

• 1: The Scrum Guide2, page 6
• 2: The Scrum Guide

The Scrum Guide defines a Scrum Team as “a cohesive unit of professionals focused on one objective at a time, the Product Goal”. It also states that “the Scrum Team consists of one Scrum Master, one Product Owner, and Developers”. Therefore, the correct answer is A, B, and D. Customers and users are not part of the Scrum Team, but they are important stakeholders who provide feedback and input to the Product Owner and the Developers.

The Scrum Team can maintain the Product Backlog to maximize its transparency by continually keeping it up to date with the most recent insights because:

• It reflects the current state of the product and the work. The Product Backlog is a dynamic and emergent artifact that represents all the possible features, functions, requirements, enhancements, and fixes that constitute changes to the product. By updating it frequently, the Scrum Team can ensure that the Product Backlog is accurate, complete, and relevant.
• It enables the Product Owner to optimize the value of the product and the work of the Scrum Team. The Product Owner is accountable for effective Product Backlog management, which includes ordering, refining, and communicating the Product Backlog items. By updating it frequently, the Product Owner can incorporate new learnings, feedback, opportunities, and changes into the product decisions and priorities.
• It supports the inspection and adaptation of the Scrum Team and the stakeholders. The Product Backlog is a source of information and transparency for everyone involved in the product development. By updating it frequently, the Scrum Team and the stakeholders can inspect the progress and outcomes of each Sprint, and adapt their plans and actions accordingly.

When multiple Scrum Teams are working on the same product, they should integrate their Increments every Sprint because:

• It allows them to accurately inspect what is done and what is potentially releasable. By integrating their work frequently, they can ensure that the product is in a usable and valuable state at the end of each Sprint, and that it meets the Definition of Done and the Sprint Goal.
• It enables them to adapt to changes and feedback faster. By integrating their work frequently, they can reduce the complexity and risk of integration, and discover and resolve any issues or dependencies sooner. They can also incorporate any new insights or requirements into their Product Backlog and Sprint Planning.
• It fosters collaboration and alignment among the teams. By integrating their work frequently, they can share their learnings and best practices, and coordinate their efforts towards a common vision and goal. They can also leverage the collective intelligence and creativity of the teams to deliver a better product.

References:

• Scrum Guide 2020, page 10: “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.”

A Scrum Master does not fulfill the same role as a traditional Project Manager. A Project Manager is typically responsible for planning, executing, monitoring, controlling, and closing a project, as well as managing the scope, schedule, budget, quality, risks, and stakeholders of the project1. A Scrum Master is a servant-leader for the Scrum Team, who helps the team understand and enact Scrum values, principles, and practices, and removes impediments to the team’s progress2. A Scrum Master does not manage the project, the scope, the schedule, the budget, or the team, as these are either shared responsibilities or emergent outcomes of the Scrum framework[3][3]. A Scrum Master also does not have authority over the team or the stakeholders, but rather facilitates collaboration and empowerment among them4.

Non-functional requirements are the criteria that define the quality, performance, security, usability, and other aspects of a product1. They are often implicit or assumed, but they are important to make visible and explicit, as they affect the value and satisfaction of the product2. One effective way to make non-functional requirements visible is to add them to the Product Backlog, which is an ordered list of everything that is known to be needed in the product[3][3]. By adding non-functional requirements to the Product Backlog, the Product Owner and the Developers can prioritize, refine, and estimate them, and make them transparent to the stakeholders4. Another effective way to make non-functional requirements visible is to add them to the Definition of Done, which is a shared understanding of what it means for work to be complete, and ensures transparency of the quality of the work done5. By adding non-functional requirements to the Definition of Done, the Developers can ensure that every Product Backlog item and Increment meets the expected quality standards, and that the work is taken care of every Sprint.

• Customer satisfaction is a measure of how well a product or service meets or exceeds the expectations and needs of the customers. It is an important indicator of the value and quality of a product or service, and it can affect the loyalty, retention, and profitability of the customers.
• Customer satisfaction should be measured frequently, as it can change over time depending on various factors, such as the market conditions, the customer feedback, the product updates, the competitor actions, and the customer behavior. Measuring customer satisfaction frequently can help the Product Owner and the Scrum Team to inspect and adapt their product vision, strategy, roadmap, backlog, and increments based on the customer needs and preferences. It can also help them to identify and resolve any issues or gaps that may affect the customer satisfaction and value delivery.
• Measuring customer satisfaction quarterly, daily, or annually is not optimal, as it may not reflect the current state of the customer satisfaction and may miss some opportunities or risks that may arise in between the measurement intervals. Quarterly measurement may be too slow to respond to the fast-changing market and customer demands. Daily measurement may be too noisy and costly to collect and analyze. Annual measurement may be too outdated and irrelevant to inform the product decisions.

Scrum does not require that the Product Owner must use any of the following items:

• Burndown chart: A burndown chart is a graphical representation of work left to do versus time. It can be used to track progress and forecast completion dates of projects or Sprints. However, it is not mandatory or prescribed in Scrum. It is one of the possible techniques that a Product Owner may use to monitor and communicate product development.
• Feature burn-up: A feature burn-up chart is a graphical representation of features completed versus time. It can be used to track progress and forecast scope changes of projects or Sprints. However, it is not mandatory or prescribed in Scrum. It is one of the possible techniques that a Product Owner may use to monitor and communicate product development.
• Critical Path Analysis: Critical Path Analysis is a project management technique that identifies the sequence of tasks that must be completed on time for a project or Sprint to finish on schedule. It can be used to plan, monitor, and control complex projects or Sprints. However, it is not mandatory or prescribed in Scrum. It is one of the possible techniques that a Product Owner may use to manage product development.
• Project Gantt chart: A project Gantt chart is a graphical representation of tasks, dependencies, durations, and milestones of a project or Sprint. It can be used to plan, monitor, and control complex projects or Sprints. However, it is not mandatory or prescribed in Scrum. It is one of the possible techniques that a Product Owner may use to manage product development.

Therefore, the correct answer is none of the above.

The Scrum Guide states that “the Developers are the people in the Scrum Team that are committed to creating any aspect of a usable Increment each Sprint”. It also states that “the Developers can do the work of any other role on the Scrum Team, as long as accountability is met”. Therefore, the Developers on the Scrum Team should write the user documentation, as it is part of the Definition of Done and the work needed to deliver a “Done” Increment. The other options are not acceptable, as they violate the Scrum values of commitment, focus, and respect, and they create dependencies, delays, and waste.

The Developers are the ones who determine how many Product Backlog items they select for a Sprint. The Developers are self-managing and decide how much work they can do in a Sprint1. The Product Owner and the Developers collaborate on the scope of the Sprint during Sprint Planning, but the final decision is up to the Developers2. The Product Owner, the Scrum Master, and the stakeholders do not have the authority to tell the Developers how many Product Backlog items they should select, as this would violate the principle of self-management[3][3].

The Sprint Backlog is the output of the Sprint Planning, where the Developers select the Product Backlog items that they can deliver in the Sprint and create a plan for how to do the work. The Scrum Guide states that "The Sprint Backlog is composed of the Sprint Goal (why), the set of Product Backlog items selected for the Sprint (what), as well as an actionable plan for delivering the Increment (how)."1 The Sprint Backlog is owned and managed by the Developers, who can update it throughout the Sprint as more is learned. The Sprint Backlog makes visible all the work that the Developers identify as necessary to meet the Sprint Goal.1

• 1: The Scrum Guide2, page 15

The reasons why it is important that there is only one Product Owner per product are:

• It is clear who is accountable for the ultimate value of the product. The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. They are responsible for identifying and articulating the Product Goal, which is a long-term objective for the product that guides all the activities of the Scrum Team.
• It helps avoid barriers to effective communication and rapid decision-making. The Product Owner is the sole person responsible for managing the Product Backlog, which is an emergent, ordered list of what is needed to improve the product. They must ensure that the Product Backlog is transparent, visible, and understood by everyone who needs to work on it. They must also collaborate with the Developers and the stakeholders to refine, order, and prioritize the Product Backlog items based on value and impact.
• The Scrum Team always knows who determines the order of the Product Backlog. The Product Owner has the final authority to decide what items are more important and valuable for the product. They must communicate this order clearly and consistently to the Scrum Team and the stakeholders. They must also respect and support the self-management of the Developers in choosing how best to accomplish their work.

Other options, such as the Scrum Master knowing who acts as their backup while on vacation or it would confuse the stakeholders if they had to work with more than one person, are not valid reasons why it is important that there is only one Product Owner per product. They may reflect a misunderstanding of the roles and accountabilities of the Scrum Team or the stakeholders.

The Definition of Done is a shared understanding of what it means for work to be complete, and ensures transparency of the quality of the work done1. The Increment is the sum of all the Product Backlog items completed during a Sprint and the value of the increments of all previous Sprints2. The Increment must be usable and potentially releasable, meaning that it meets the quality standards set by the Scrum Team and the stakeholders[3][3]. Doing all work needed to meet the Definition of Done enhances the transparency of the Increment, as it ensures that the Increment is truly done and reflects the current state of the product4. The other options do not enhance the transparency of the Increment, as they either introduce unnecessary complexity, delay, or overhead, or do not provide a clear and consistent way to measure the quality of the work done.

Scrum is a framework that is designed to be lightweight and easy to adopt. To get started with Scrum, the minimal requirements are indeed a Product Owner with enough ideas for a first Sprint, a Development Team to implement those ideas, and a Scrum Master to facilitate and guide the process. This aligns with the core principles of Scrum, which emphasize self-organization, collaboration, and the ability to deliver increments of value quickly and frequently.

References: The Scrum Guide outlines the roles within a Scrum Team and the necessity of having a Product Backlog with enough ‘Ready’ items to fill a Sprint. The guide also emphasizes the importance of having a clear definition of ‘Done’ before starting the first Sprint

A product’s success is measured by the value it delivers to the customers and the organization. The impact on cost, revenue, and customer satisfaction are three important indicators of value. The Scrum Guide states that "The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team."1 The Product Owner should consider the cost of developing and maintaining the product, the revenue generated by the product, and the satisfaction of the customers and users who use the product. These factors help the Product Owner to prioritize the Product Backlog, define the Product Goal, and collaborate with the stakeholders.

• The “cone of uncertainty” is a graphical representation of the degree of uncertainty in a project estimate over time. It shows that the range of possible outcomes is wider at the beginning of the project and narrows down as the project progresses and more information becomes available.
• The “cone of uncertainty” can be used to illustrate that as a project forecast lengthens, it is increasingly less certain. This means that the longer the time horizon for a project, the more variability and risk there is in the estimate. This also implies that shorter iterations and frequent feedback can help reduce uncertainty and improve accuracy.
• The “cone of uncertainty” cannot be used to determine whether to cut quality, similar to the “Iron Triangle” of project management. The “Iron Triangle” is a model that shows the trade-offs between scope, time, and cost in a project. Quality is often considered as a fourth dimension that is affected by these three factors. Cutting quality is not a desirable option for any project, especially for Scrum projects that value delivering high-quality products that meet customer needs.
• The “cone of uncertainty” cannot be used to determine the cost of a project before it begins. The cost of a project depends on many factors, such as the scope, the resources, the complexity, the risks, and the market conditions. The “cone of uncertainty” only shows the range of possible outcomes based on the available information at a given point in time. It does not provide a definitive or accurate estimate of the cost before the project starts.
• The “cone of uncertainty” cannot be used to determine the length of the next Sprint. The length of the next Sprint is determined by the Scrum Team based on their empirical experience and their ability to deliver a potentially releasable Increment of value. The “cone of uncertainty” does not provide any guidance on how long a Sprint should be or how much work can be done in a Sprint.

Sprint 0 is a term that some organizations use to describe a phase of work before the first official Sprint, where they do some upfront planning, design, architecture, or analysis1. However, this term is not consistent with the Scrum framework, which does not prescribe any pre-Sprint activities or phases2. Scrum starts with a Product Backlog that contains at least one valuable and feasible Product Goal, and enough Product Backlog items to initiate the first Sprint[3][3]. The Product Owner is accountable for maximizing the value of the product and the work of the Developers, and for managing the Product Backlog4. The Product Owner does not have any specific accountability during Sprint 0, because Sprint 0 is not a part of Scrum.

According to Scrum.org, the Developers own the Sprint Backlog12. The Sprint Backlog is a plan by and for the Developers1. It is a highly visible, real-time picture of the work that the Developers plan to accomplish during the Sprint in order to achieve the Sprint Goal1. Consequently, the Sprint Backlog is updated throughout the Sprint as more is learned1.

According to Scrum.org, the Developers who will be doing the work are responsible for the sizing of Product Backlog items1. The Product Owner may influence the Developers by helping them understand and select trade-offs1. This implies that the Developers size the items after clarifying requirements with the Product Owner1.

The amount of the Sprint Backlog that must be defined during the Sprint Planning event is enough so the Developers can create their forecast of what work they can do. This is because:

• Sprint Planning is an event where the Scrum Team plans for the upcoming Sprint. The purpose of Sprint Planning is to align the entire Scrum Team around a common goal and a plan for delivering an Increment that meets that goal.
• The Developers are accountable for creating a Sprint forecast, which is a selection of Product Backlog items that they intend to work on during the Sprint. The Sprint forecast should be realistic, achievable, and valuable.
• The Developers are also accountable for creating a plan for how they will deliver the selected Product Backlog items as a “Done” Increment. The plan may include tasks, dependencies, risks, estimates, or other information that helps them organize and manage their work.
• The amount of the Sprint Backlog that must be defined during Sprint Planning may vary depending on the context, complexity, and uncertainty of the product development. However, it should be enough so that the Developers can create their forecast of what work they can do and have a clear direction for the first few days of the Sprint.

Other options, such as just enough to understand design and architectural implications, the entire Sprint Backlog being identified and estimated by the end of Sprint Planning, or just enough tasks for the Scrum Master to be confident in the Developers’ understanding of the Sprint, are not valid answers as they do not reflect what must be defined during Sprint Planning or what is required for creating a Sprint forecast.

The Sprint Retrospective is an event for the Scrum Team to inspect how the last Sprint went with regards to individuals, interactions, processes, tools, and their Definition of Done1. The purpose of the Sprint Retrospective is to plan ways to increase quality and effectiveness for the next Sprint2. Therefore, appropriate topics for discussion during a Sprint Retrospective are:

Identifying high priority process improvements for the next Sprint. The Scrum Team should identify the most important things that went well and the potential improvements, and create a plan for implementing some of them in the next Sprint[3][3]. This way, the Scrum Team can continuously improve their performance and deliver more value.

How the team collaborates. The Scrum Team should reflect on how they work together as a self-managing unit, and how they can enhance their skills, tools, and relationships4. This way, the Scrum Team can foster a culture of trust, respect, and collaboration.

The other options are not appropriate topics for discussion during a Sprint Retrospective, as they are either related to the Product Backlog or the Sprint Backlog, which are not the focus of the Sprint Retrospective. The order of items in the Product Backlog is the responsibility of the Product Owner, who manages the Product Backlog based on the value, risk, and dependencies of the items5. The Product Owner may seek input from the Scrum Team or the stakeholders, but the final decision is up to the Product Owner. Documenting acceptance criteria for items in the next Sprint is part of the Product Backlog refinement, which is an ongoing activity throughout the Sprint, not a specific event. The Scrum Team should collaborate on refining the Product Backlog items and adding more details, such as acceptance criteria, as they become more clear and ready for selection in a Sprint Planning.

 These are the best answers because they ensure that security concerns are addressed in a transparent and consistent way. By adding security criteria to the Definition of Done, the Scrum Team can make sure that every Increment meets a high standard of quality and security. By creating Product Backlog items for specific security concerns, the Scrum Team can prioritize and plan them in collaboration with the Product Owner and stakeholders. References:

• False: Product Owners do not have to specify complete acceptance criteria for a Product Backlog item before the Developers can select the item in Sprint Planning.
• Acceptance criteria are a set of conditions that a Product Backlog item must satisfy to be considered “Done” and acceptable for delivery.
• Acceptance criteria are not mandatory in Scrum, but they can help the Product Owner and the Developers to clarify the expectations and requirements of a Product Backlog item.
• Acceptance criteria can be added or refined by the Product Owner at any time, but they should be clear and testable before the Sprint starts.
• The Developers can select a Product Backlog item in Sprint Planning based on their understanding of its value, scope, and complexity, as well as their capacity and skills. They can also collaborate with the Product Owner to define or refine the acceptance criteria during Sprint Planning. References: Scrum Guide, Section 3.4 (The Product Backlog), Section 5.1 (Sprint Planning), and Section 6.4 (The Increment)
