The best way to determine if the Product Owner is interacting with the Developers enough throughout a Sprint is to observe whether both parties are satisfied with the Increment.The Increment is a concrete stepping stone toward the Product Goal1.It must be usable and meet the Definition of Done1.The Product Owner is accountable for maximizing the value of the product resulting from the work of the Developers1.The Developers are accountable for creating a valuable, useful, and potentially releasable Increment every Sprint1. Therefore, if both the Product Owner and the Developers are happy with the quality and value of the Increment, it means that they have communicated and collaborated effectively throughout the Sprint.

Some reasons why the other options are not correct are:

A: The Developers should determine the percentage of time the Product Owner is required to be present and monitor whether the Product Owner's average presence is around this figure. This option is not correct because it implies that there is a fixed or optimal amount of time that the Product Owner should spend with the Developers, which may not be true. The Product Owner's interaction with the Developers may vary depending on the context, complexity, and uncertainty of the product and the Sprint.The Scrum Guide does not prescribe any specific time or frequency for the Product Owner's involvement with the Developers1.The Product Owner should be available to provide guidance and feedback to the Developers as needed, but not interfere with their self-organization and autonomy1.

B: Check the Daily Scrum reports to see whether the Product Owner was present at the majority of the Daily Scrum meetings. This option is not correct because it assumes that the Daily Scrum is a meeting where the Product Owner should be present, which is not true.The Daily Scrum is an event for and by the Developers12, not for reporting or accountability to anyone else.The Product Owner may attend as an observer or a collaborator, but only if invited by the Developers12. The presence or absence of the Product Owner at the Daily Scrum does not indicate how much they interact with the Developers throughout the Sprint.

C: Observe whether the Developers need to ask the Product Owner questions at times other than during the Daily Scrum. This option is not correct because it implies that asking questions is a sign of insufficient interaction, which may not be true. Asking questions is a natural and healthy part of communication and collaboration between the Product Owner and the Developers. It shows that they are engaged, curious, and willing to learn from each other. It also helps them to clarify requirements, expectations, and feedback, and to resolve any ambiguities or conflicts. Asking questions does not necessarily mean that there is a lack of interaction, but rather that there is a need for more information or clarification.

According to the Scrum Guide 2020, the Scrum Team commits to achieving the Sprint Goal and creating a valuable product Increment every Sprint1.The Sprint Goal is a short statement that provides direction and focus for the Scrum Team throughout the Sprint2.The product Increment is a concrete and usable outcome that meets the Definition of Done and adds value to the product3. Therefore, the Scrum Team commits to:

Working towards the Sprint Goal.This means that the Scrum Team collaborates and coordinates their work to deliver a product Increment that satisfies the Sprint Goal.The Sprint Goal is chosen by the Scrum Team during Sprint Planning, based on the Product Backlog items that they forecast to complete in the Sprint2.The Sprint Goal provides coherence and alignment for the Scrum Team, and helps them cope with complexity and uncertainty4.

Seeking stakeholder feedback.This means that the Scrum Team engages with the stakeholders and customers who have an interest or influence on the product. The Scrum Team seeks their feedback to inspect and adapt the product Increment and the Product Backlog, and to validate their assumptions and hypotheses. The Sprint Review is an event where the Scrum Team and the stakeholders collaborate on what was done in the Sprint and what to do next.

Upholding transparency.This means that the Scrum Team makes all aspects of their work visible to those who are responsible for the outcome. Transparency enables inspection and adaptation, which are essential for empiricism. The Scrum Team upholds transparency by using the Scrum artifacts (Product Backlog, Sprint Backlog, and Increment) as sources of information and progress, and by having frequent and honest communication among themselves and with the stakeholders.

The other options are not correct because:

Getting all the forecast work in the Sprint Plan done.This option is incorrect because it implies that the Scrum Team is committed to a fixed scope of work, rather than a flexible goal. The Scrum Guide 2020 states that ''the Developers do not commit to completing all of the work planned during a Sprint Planning'' but rather ''they plan their work as they perform it throughout the Sprint''. The Scrum Team can modify their Sprint Backlog during the Sprint as needed, as long as they do not endanger the Sprint Goal.

Increasing velocity.This option is incorrect because it implies that the Scrum Team is committed to a metric that is not part of the Scrum framework. Velocity is a measure of how much work a team can deliver in a given time period, usually based on story points or hours. However, velocity is not a reliable indicator of value or quality, and it can vary depending on many factors, such as team size, complexity, dependencies, etc. The Scrum Guide 2020 does not mention velocity as a commitment or an artifact of the Scrum Team.

Having the Product Owner available to the Developers on a daily basis.This option is incorrect because it implies that the Product Owner is not part of the Scrum Team, but rather an external stakeholder. The Scrum Guide 2020 states that ''the Product Owner is one person who is a member of the Scrum Team'' and ''is accountable for maximizing value resulting from work of Developers''. The Product Owner collaborates closely with the Developers throughout the Sprint, not only by being available, but also by providing vision, guidance, feedback, and clarification.

This is the best answer because it is consistent with the Scrum Master's accountability to educate and coach the Scrum Team and the organization on the Scrum framework and its principles12.By coaching the Product Owner and the Developers on the purpose of Scrum events, the Scrum Master can help them understand that the Daily Scrum is not a status report or a performance review, but a time to inspect and adapt their progress toward the Sprint Goal34.By letting them figure out how to deal with this situation, the Scrum Master can also respect and enable their self-organization and collaboration12.

User documentation is part of your Definition of Done, which means that it is a requirement for delivering a potentially releasable product increment. Your Scrum Team cannot ignore or postpone this requirement, even if there are not enough technical writers for all teams. Your Scrum Team is responsible for creating and maintaining the user documentation, and the Developers are the ones who have the skills and authority to do so. The Scrum Master can help the Developers learn how to write effective user documentation, and the Product Owner can provide feedback on its quality and value.

Scrum Guide 2020, page 9: ''The Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product.''

Scrum Guide 2020, page 10: ''The Developers are the people in the Scrum Team that are committed to creating any aspect of a usable Increment each Sprint.''

Professional Scrum Master II Course, page 12: ''The Definition of Done is a crucial aspect of transparency. If it is not clear when work is done, then stakeholders may make wrong assumptions about the state of the software.''

A: Arrange one-on-one coaching sessions where concerns the Scrum Master has identified can be discussed. This is a good way to provide individual feedback and guidance to the Scrum Team members and other people involved in the Scrum process. The Scrum Master can help them overcome any challenges or misunderstandings they may have about Scrum.

C: Schedule group training about Scrum. This is a good way to educate and inform a larger audience about the principles and practices of Scrum. The Scrum Master can use this opportunity to share their knowledge and experience with Scrum, and answer any questions or concerns that may arise.

E: Educate stakeholders and customers about Scrum. This is a good way to ensure that the people who have a stake in the product or service understand the benefits and expectations of Scrum. The Scrum Master can help them appreciate the value of empirical feedback, transparency, and collaboration that Scrum provides.

Scrum Guide 2020, page 6: ''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.''

Professional Scrum Master II Course, page 8: ''The role of the Scrum Master is to help everyone involved in creating products with Scrum to understand, apply, and improve upon the use of the framework.''
