PSM-I Professional Scrum Master I Question and Answers

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.

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 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. 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, an appropriate action for the Scrum Master to take if the Product Owner is struggling with ordering the Product Backlog is to offer the Product Owner help in understanding that the goal of ordering the Product Backlog is to maximize value.

The Scrum Master should ask the person to share the issue with the team as soon as possible, as stated in [5]: “The Scrum Master should encourage transparency and collaboration within the team and with other stakeholders. If there is a concern about data security issues, it should be brought up to the team and discussed openly. The team can then decide how to handle it, whether by creating a Product Backlog item, updating the definition of “Done”, or taking some other action.”

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.”

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 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 Guide, three behaviors that demonstrate that a team is self-organizing are creating their own sprint backlog, having all the skills needed to create a releasable Increment, and collaboratively selecting their own work during the Sprint. The other options are not behaviors that demonstrate self-organization, as they are either contrary to Scrum values and principles (such as stakeholders walking in at the Daily Scrum or working within functional boundaries) or unnecessary for self-organization (such as the Product Owner not being at Sprint Retrospectives or the Development Team inviting external people to the Sprint Planning).

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.

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.

When many Development Teams are working on a single product, the definition of “Done” must be shared by all Development Teams and make their combined work potentially releasable, as stated in [4]: “When multiple teams work together on one product they must mutually define and comply with the same Definition of Done. This makes sure all Increments adhere to a consistent quality level.”

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 guideline that a Scrum Master should give is that estimates are made by the Development Team. 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 should estimate the work in Scrum, using any method or unit they prefer.

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.

The Developers determine how many Product Backlog items they select for a Sprint, as stated in the Scrum Guide: “The Developers select items from the Product Backlog to include in the current Sprint. The Scrum Team may refine these items during this process, which increases understanding and confidence.”

The correct answer is A, because the Scrum Guide states that “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, non-functional requirements should be part of the definition of ‘Done’ and ensure every Increment meets them.

According to the Scrum Guide1, Scrum promotes self-organization by giving autonomy and empowerment to the Developers who decide how to do their work within a Sprint. The Developers have no titles other than Developer, regardless of their specialization or skills. Scrum is a lightweight framework that minimizes prescription and maximizes flexibility and adaptability.

The correct answers are C, E, and F, because these phrases best describe the purpose of a definition of “Done”. It creates transparency over the work inspected at the Sprint Review, as it defines what it means for an Increment to be potentially releasable. It guides the Development Team in creating a forecast at the Sprint Planning, as it helps them estimate how much work they can accomplish in a Sprint. It defines what it takes for an Increment to be ready for release, as it ensures that the product meets the quality expectations of the stakeholders.

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

The correct answer is D, because there is no gap between Sprints in Scrum. The Scrum Guide states that “a new Sprint starts immediately after the conclusion of the previous Sprint.” Therefore, there is no time required after a Sprint to prepare for the next Sprint.

The correct answer is B, because there is no role called “Project Manager” in Scrum. The Scrum Guide states that “Scrum recognizes no titles for Development Team members other than Developer, regardless of the work being performed by the person; there are no exceptions to this rule.” Therefore, Scrum has only three roles: Product Owner, Scrum Master, and Developer.

According to the Scrum Guide, the Scrum Team should make sure that everyone on the team does their tasks for the Sprint, as they are collectively accountable for creating valuable Increments that meet stakeholder needs and expectations. The other options are not valid, as they imply that someone else outside the Scrum Team (such as a project manager) or another role on the Scrum Team (such as the Product Owner or the Scrum Master) is responsible for making sure that everyone does their tasks for the Sprint.

The correct answer is C, because the second Sprint starts immediately after the first Sprint. The Scrum Guide states that “Sprints have consistent durations throughout a development effort. A new Sprint starts immediately after the conclusion of the previous 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, implementation of a Product Backlog item is considered complete when the item has no work remaining in order to be potentially released.

The correct answers are A and B, because these are true about the Product Owner role. The Product Owner is one person, not a committee or a team, who is accountable for ordering the Product Backlog and maximizing the value of the product. The Scrum Guide states that “the Product Owner is responsible for maximizing the value of the product resulting from work of the Development Team. How this is done may vary widely across organizations, Scrum Teams, and individuals. … For the Product Owner to succeed, the entire organization must respect his or her decisions.”

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

According to the Scrum Guide, an Increment does not have to be released to customers or users at the end of each Sprint. However, it must be in a usable condition and meet the Definition of Done. The decision to release an Increment is made by the Product Owner, based on the value and feedback obtained from stakeholders. The other option is not valid, as it implies that releasing an Increment is mandatory at the end of each Sprint.

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.

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 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).

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 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.

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.

 According to the Scrum Guide, a Development Team needs a Sprint Goal because it provides guidance and focus for building an Increment that delivers value. The other options are not valid reasons for having a Sprint Goal, as they are either incorrect (such as giving purpose only to Sprint 0 or ensuring implementation of all Product Backlog items) or irrelevant (such as knowing everything from the Product Backlog).

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, the Developers do the work to make sure Product Backlog items conform to the Definition of Done, as they are responsible for creating a “Done” Increment that meets the Definition of Done. The other options are not valid, as they imply that the work is done by someone else outside the Development Team (such as Quality Assurance Team) or by another role on the Scrum Team (such as Product Owner or Scrum Master).

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

According to the Scrum Guide1, a Sprint can be cancelled before the Sprint time-box is over. Only the Product Owner has the authority to cancel the Sprint, although he or she may do so under influence from the stakeholders, the Developers, or the Scrum Master. A Sprint would be cancelled if the Sprint Goal becomes obsolete. This might occur if the company changes direction or if market or technology conditions change. In general, a Sprint should be cancelled if it no longer makes sense given the circumstances. But, due to the short duration of Sprints, cancellation rarely makes sense.

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

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.

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

According to the Scrum Guide, the Scrum Team is responsible for removing a Developer from the Scrum Team if necessary, as they are self-managing and accountable for creating valuable Increments. The other options are not valid, as they imply that someone else outside the Scrum Team has the authority to remove a Developer (such as the Scrum Master, the Product Owner, or the hiring manager), which is not consistent with Scrum values and principles.

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

According to the Scrum Guide, 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 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.

Only the Product Owner has the authority to cancel the Sprint, although he or she may do so under influence from the stakeholders, the Developers, or the Scrum Master. A Sprint would be cancelled if the Sprint Goal becomes obsolete. This might occur if the company changes direction or if market or technology conditions change.

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.”

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.

References: Scrum Guide

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.

 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.

According to the Scrum Guide1, 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 a result of Sprint Planning, as is the Sprint Backlog.

a burndown chart is a graphical representation of work left to do versus time. It is very useful for predicting when all of the work will be completed. It is often used in agile software development methodologies such as Scrum. However, burndown charts can be applied to any project containing measurable progress over time. A release burndown chart tracks progress across multiple Sprints towards a product release. It shows how much work remains in the Product Backlog at any given time during the release cycle. A trend line through a release burndown chart indicates when the work remaining will likely be completed if nothing changes on the Product Backlog or the Development Team.

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?"

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.

According to the Scrum Guide1, Scrum does not require or provide any specific techniques or methods for product definition. Rather, Scrum provides a framework with roles, rules, and events within which complex products can be developed. To get started in terms of what to build, Scrum requires no more than a Product Owner with enough ideas for a first Sprint, a Development Team to implement those ideas and a Scrum Master to help guide the process.

References: Scrum Guide

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

According to the Scrum 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. Sprints have consistent durations throughout a development effort. A new Sprint starts immediately after the conclusion of the previous Sprint. The length of a Sprint should be short enough to keep the business risk acceptable to the Product Owner, short enough to be able to synchronize the development work with other business events, and no more than one calendar month.

References: Scrum Guide

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

The best answer is C. When multiple Scrum Teams are working on a single product, they must mutually define and comply with the same Definition of Done1. This ensures that the product has a consistent level of quality and that the Increments delivered by different teams can be integrated seamlessly. Having different Definitions of Done for each team can lead to confusion, rework, and technical debt. The Scrum Guide says that the Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product2. Therefore, it is not something that can be decided by the Scrum Masters alone (B) or left to each team’s discretion (A and D).

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 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.

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.”

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

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

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