If the Scrum Team cannot complete its work by the end of the Sprint, the Sprint does not get extended. Instead, the unfinished Sprint Backlog Items go back to the Product Backlog and can be addressed in the following Sprint12. This approach allows the team to get better at estimating and reduces complexity due to the consistency of the Scrum Events2. The Scrum Team continuously learns and adapts12.

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

the Product Owner is responsible for refining the Product Backlog, which is an ongoing activity that can occur at any time, including between Sprints. The other options are not typical activities for the Product Owner between Sprints, as the next Sprint starts immediately after the current Sprint1, the project plan is replaced by the Product Backlog2, and the Quality Assurance is done by the Developers of the Scrum Team within the Sprint1.

• The best statement that describes Scrum is: A framework to generate value through adaptive solutions for complex problems.
• Scrum is a lightweight framework that helps people, teams, and organizations to deliver valuable products in complex and uncertain environments.
• Scrum is based on empiricism, which means that knowledge comes from experience and making decisions based on what is observed. Scrum employs an iterative and incremental approach to optimize predictability and control risk.
• Scrum is not a defined and predictive process, a complete methodology, or a cookbook that defines best practices. Scrum provides the minimal boundaries within which teams can self-organize and create innovative solutions. References: Scrum Guide, Section 1 (Definition of Scrum) and Section 2 (Uses of Scrum)

Sprints are fixed-length events of one month or less that serve as a container for the other Scrum events and activities. Sprints have consistent durations throughout a development effort. A new Sprint starts immediately after the conclusion of the previous Sprint. There is no gap or downtime between Sprints. The second Sprint starts right after the first Sprint, regardless of the customer acceptance testing, the architectural changes, or the Product Backlog items.

The Scrum Guide states that "By the end of the Sprint Retrospective, the Scrum Team should have identified improvements that it will implement in the next Sprint. Implementing these improvements in the next Sprint is the adaptation to the inspection of the Scrum Team itself."1 This means that the Scrum Team may add the high priority process improvements to the Sprint Backlog for the next Sprint, as part of their plan to deliver the Increment and achieve the Sprint Goal. The Sprint Backlog is owned and managed by the Developers, who can update it throughout the Sprint as more is learned.1

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.

 The best way to minimize dependencies between the Scrum Teams is to work with the Developers on how to best analyze and break apart the work. 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 Developers are self-managing professionals who organize and manage their own work. They decide how to best accomplish their work, rather than being directed by others outside the Scrum Team.
• The Developers are cross-functional, meaning they have all the skills and competencies needed to accomplish the work without depending on others who are not part of the team.
• 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.
• 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.
• 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.
• When there are multiple teams working on one product, it is important to minimize dependencies between them to avoid delays, conflicts, or waste. Dependencies may arise due to technical, functional, or organizational factors that affect how the teams can deliver value independently and effectively.
• To minimize dependencies, the Product Owner should work with the Developers on how to best analyze and break apart the work into smaller and more manageable pieces that can be delivered by each team without relying on others. This may involve applying techniques such as feature slicing, component splitting, or domain-driven design. The Product Owner should also communicate and coordinate with other Product Owners and stakeholders to align expectations and priorities across teams.

Other options, such as creating an independent Product Backlog per Scrum Team, dividing Product Backlog items among six Product Owners, identifying the dependencies and re-ordering the Product Backlog for the other five Product Owners, or raising this as an impediment with the Scrum Master, are not valid answers as they do not reflect how to minimize dependencies between the Scrum Teams or how to apply the Scrum values and principles.

The Developers are the people in the Scrum Team who are committed to creating any aspect of a usable Increment each Sprint. The Developers are accountable for organizing and managing their work. Only the Developers can decide how to perform the work during the Sprint1. The Developers plan the work necessary to create an Increment that meets the Definition of Done during the Sprint Planning event. This is often done by decomposing Product Backlog items into smaller work items of one day or less. How this is done is at the sole discretion of the Developers. The Sprint Backlog is the set of Product Backlog items selected for the Sprint, plus a plan for delivering the product Increment and realizing the Sprint Goal1. The Developers are responsible for creating and maintaining the Sprint Backlog1. The Developers are not accountable for selecting the Product Owner, reporting productivity, or any other activities that are not related to creating a Done Increment that meets the Sprint Goal123.
