The Daily Scrum is a 15-minute event for the Developers of the Scrum Team to inspect progress toward the Sprint Goal and adapt the Sprint Backlog as necessary, adjusting the upcoming planned work. The Daily Scrum is not a status meeting, but a way for the Developers to collaborate and self-organize around the most important work for the next 24 hours. The Daily Scrum also provides an opportunity for the Developers to identify and communicate any impediments that are hindering their progress, and request help from the Scrum Master or other team members to resolve them.

A Product Backlog item is a description of a feature or functionality that adds value to the product. It is selected by the Scrum Team during the Sprint Planning, based on the Product Owner's proposal and the Developers' forecast. It is expected that the Product Backlog item will be completed by the end of the Sprint, meaning that it meets the Definition of Done, which is a formal description of the state of the Increment when it meets the quality standards required for the product.

However, if a Product Backlog item is not completed by the end of the Sprint, meaning that it does not meet the Definition of Done, then:

The item is not included in the Increment for this Sprint (B), which is a valid option as it ensures that only ''Done'' work is delivered to the customer and stakeholders. The Increment is a concrete and usable outcome of a Sprint that provides value and feedback. It should not contain any undone or partially done work that may compromise its quality, usability, or value.

It is put on the Product Backlog for the Product Owner to decide what to do with it (D), which is another valid option as it respects the authority and accountability of the Product Owner to manage the Product Backlog, which is an ordered list of what is needed in the product. The Product Owner can decide whether to re-prioritize, re-estimate, refine, or remove the incomplete Product Backlog item based on new insights and stakeholder needs.

The other options are not correct because they:

Review the item, add the done part of the estimate to the velocity and create a Story for the remaining work (A), which is not a good option as it violates the principle of commitment and transparency that underlies the Definition of Done. The Scrum Team should not count or report any work that is not ''Done'' as part of their progress or performance. The Scrum Team should also not split or create new Product Backlog items during or after the Sprint, as this may affect their alignment and focus on the Sprint Goal.

Only the stakeholders decide over acceptance of undone work and whether to release it , which is not a good option as it violates the role and responsibility of the Product Owner and the Developers to deliver a potentially releasable Increment at the end of each Sprint. The stakeholders can provide feedback and suggestions for the product, but they cannot accept or release any work that does not meet the Definition of Done.

The most effective way to recover is to restore transparency and trust by informing the Product Owner that the progress she has perceived to date is not correct.The Increment is not releasable because it does not meet the Definition of Done12, which is a shared understanding of what it means for work to be complete12. The Developers should give the Product Owner their estimate of the effort it would take to get the past work done, and suggest doing that work first before proceeding with new features.This way, the Developers can ensure that they deliver a valuable, useful, and potentially releasable Increment every Sprint12. The Developers should also re-estimate the effort to complete the remaining backlog, including all testing, and communicate any changes or risks to the Product Owner.In the end, it is the Product Owner's call to continue the project or to cancel it, based on the value and feasibility of the product12.

Some reasons why the other options are not correct are:

A: The Developers set the open work aside to be performed in one or more release Sprints. They remind Marian to find funding for enough Release Sprints in which this remaining work can be done. This option is not correct because it violates the Scrum framework and the Scrum values.The Scrum framework does not prescribe any release Sprints or separate phases for testing or integration12.The Scrum values include commitment, focus, openness, respect, and courage12. The Developers should commit to delivering a potentially releasable Increment every Sprint, not postpone or hide their undone work. The Developers should focus on creating value for the customers and users, not on meeting artificial deadlines or metrics. The Developers should be open and honest about their progress and challenges, not mislead or deceive the Product Owner.The Developers should respect the Product Owner's authority and accountability for maximizing the value of the product and the work of the Developers12, not shift the responsibility or blame to them. The Developers should have the courage to face their problems and seek help, not avoid or ignore them.

B: Transparency needs to be restored by adding the undone work to the Product Backlog. The Developers must figure out a way to deliver in the upcoming Sprints a velocity of not only 13 units of new work, but also two additional points to catch up undone work. It is the Scrum Master's duty to assess whether such repair is possible. If not, the Scrum Master initiates a restart with a more reliable team or cancels the project. The Scrum Master will have to inform Product Owner and the stakeholders. This option is not correct because it violates the Scrum framework and the Scrum roles.The Scrum framework does not prescribe any velocity or points as measures of progress or success12.The Scrum roles include Product Owner, Scrum Master, and Developers12.The Product Owner is accountable for maximizing the value of the product and the work of the Developers12, not for tracking or controlling their velocity or points.The Scrum Master is accountable for establishing Scrum as defined in the Scrum Guide1, causing change that increases the productivity of the Scrum Team1, and working with other Scrum Masters to increase the effectiveness of the application of Scrum in the organization1, not for assessing or judging the performance of the Developers or initiating a restart or cancellation of the project.The Developers are accountable for creating a valuable, useful, and potentially releasable Increment every Sprint12, not for meeting a predetermined velocity or points target.

C: In the next Sprints, the Developers keep making sure that all of the selected scope per Sprint is as done as possible, at least at the past level of 90%. In every Sprint the undone work of the previous Sprint is estimated and added to the Sprint Backlog. It comes on top of the expected forecast of 13 units, so it does not mess up progress on the product Backlog. This option is not correct because it violates the Scrum framework and the Scrum values.The Scrum framework requires that each Sprint delivers a potentially releasable Increment that meets the Definition of Done12, not a partially done or incomplete product that accumulates technical debt or quality issues.The Scrum values include commitment, focus, openness, respect, and courage12. The Developers should commit to delivering a potentially releasable Increment every Sprint, not compromise on quality or value. The Developers should focus on creating value for the customers and users, not on meeting artificial deadlines or metrics. The Developers should be open and honest about their progress and challenges, not hide or ignore their undone work.The Developers should respect the Product Owner's authority and accountability for maximizing the value of the product and the work of the Developers12, not burden them with additional work or risk. The Developers should have the courage to face their problems and seek help, not avoid or ignore them.

B: The Scrum Master coaches the Scrum Team and the organization how to work empirically. This is a true statement, as the Scrum Master is responsible for helping everyone understand and apply the principles and practices of Scrum, which is based on empirical process control. The Scrum Master can teach the Scrum Team and the organization how to use transparency, inspection, and adaptation to deliver valuable products in a complex environment.

C: The Scrum Master facilitates Scrum events as requested or needed. This is a true statement, as the Scrum Master is responsible for ensuring that all Scrum events take place and are positive, productive, and kept within the timebox. The Scrum Master can facilitate the communication and collaboration among the Scrum Team and the stakeholders during the Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective.

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.''

According to the Large-Scale Scrum (LeSS) framework, one of the principles for scaling agile development is to descale the organization, which means simplifying the structure and reducing dependencies and handoffs. A well-structured Product Backlog can help achieve this by enabling feature teams, which are cross-functional and cross-component teams that can deliver a complete customer-centric feature. Feature teams minimize and often eliminate Developers working on multiple Scrum Teams during a Sprint, as they can focus on one Product Backlog item at a time. This also improves productivity, quality, and learning, as Developers can avoid context switching and multitasking, which are known to reduce efficiency and effectiveness. A person working on multiple Scrum Teams at the same time is often less productive than when that person can focus on the Sprint Backlog of a single Scrum Team.

The Large-Scale Scrum (LeSS) framework also states that Scrum does not change when scaling up to multiple teams. The core Scrum framework remains intact, with one Product Owner, one Product Backlog, and potentially releasable Increments every Sprint. The only changes are adding a few coordination practices to cope with the increased complexity and interdependencies. Therefore, changes to the core Scrum framework are not needed to be successful with Scrum at large scale.

Scrum Team members do not have to be working full time on a team, as long as they are committed to the Sprint Goal and deliver a Done Increment every Sprint. However, it is recommended that they spend as much time as possible with their team, as this fosters collaboration, communication, and alignment.
