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.

In Scrum, there is only one product and one Product Backlog for a given product. The Product Backlog is the single source of truth for the Scrum Team and the stakeholders. It contains all the requirements, features, functions, enhancements, fixes, and anything else that can deliver value to the customers and users of the product. The Product Backlog is ordered by the Product Owner based on the product vision, goals, and value.

Having multiple Product Backlogs for one product would create confusion, duplication, inconsistency, and waste. It would also make it harder to align the Scrum Teams and the stakeholders on the same product direction and priorities. Therefore, each Scrum Team should not have a separate Product Backlog.

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.

Having multiple Product Owners for one product would create conflicts, overlaps, gaps, and inefficiencies. It would also make it harder to maintain a clear and consistent product vision, strategy, roadmap, and backlog. Therefore, there should be only one Product Owner for one product.

In some cases, when there are multiple Scrum Teams working on one product, it may be necessary to have some form of scaling or coordination mechanism to ensure alignment and collaboration among the teams. However, this does not mean that there should be multiple Product Owners or Product Backlogs. Instead, there should be ways to facilitate communication, feedback, integration, and transparency among the teams and with the Product Owner. For example, some frameworks or practices that can help with scaling Scrum are Nexus, LeSS, SAFe, or Scrum of Scrums.

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.

The correct answer isC.

The purpose of every Sprint, including the first Sprint, is to create a valuable, useful Increment. Scrum is based on empiricism, meaning teams learn through doing, inspecting results, and adapting. Therefore, the first Sprint should produce something tangible and valuable rather than focusing only on long-term planning or documentation.

Why the other options are incorrect:

A. Make up a plan for the rest of the project— Scrum does not require full up-front planning for the whole project. Plans emerge and adapt over time.

B. Define the major product features and a release plan architecture— this may happen in some organizations, but it is not the main purpose of the first Sprint.

D. Analyze, describe, and document the requirements for the subsequent Sprints— Scrum is not a phase-based requirements process. The goal is to deliver value each Sprint.

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

Correct Answers: A, C, and D.

The Sprint Retrospective is an event where the Scrum Team reflects on how they worked together in the last Sprint and identifies ways to improve their collaboration, processes, and quality. Therefore, appropriate topics for discussion in a Sprint Retrospective are:

Team relations: The Scrum Team should discuss how they communicated, interacted, and supported each other during the Sprint. They should celebrate their successes, acknowledge their challenges, and address any conflicts or issues that arose. They should also share feedback, appreciation, and suggestions for improvement with each other.

How the Scrum Team does its work: The Scrum Team should inspect the methods, tools, and practices they used to deliver the product increment. They should evaluate what worked well and what could be improved. They should also identify any impediments, risks, or dependencies that affected their work and how they handled them.

Definition of Done: The Scrum Team should review their Definition of Done and check if it is still relevant, clear, and achievable. They should also assess how well they adhered to it and if they delivered a potentially releasable product increment that meets the quality standards. They should also consider if they need to update or adapt their Definition of Done based on new insights or feedback.

The following topics are not appropriate for discussion in a Sprint Retrospective:

The value of work currently represented in the Product Backlog: The value of the Product Backlog items is the responsibility of the Product Owner, who should continuously refine and order them based on stakeholder needs and feedback. The value of the Product Backlog items is not directly related to how the Scrum Team works together and does not affect their improvement actions for the next Sprint.

Arranging the Sprint Backlog for the next Sprint: The Sprint Backlog is the plan for the next Sprint that is created by the Scrum Team during the Sprint Planning event. The Sprint Backlog is based on the Product Backlog items that are selected for the next Sprint and how the Developers intend to accomplish them. The Sprint Retrospective is not a planning event but a reflection event that focuses on the past Sprint.

[Scrum Guide], section 3.5: “The purpose of the Sprint Retrospective is to plan ways to increase quality and effectiveness.”

[Professional Scrum Product Owner], chapter 7: “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.”

What is a Sprint Retrospective? | Scrum.org: “During each Sprint Retrospective, the Scrum Team plans ways to increase product quality by improving work processes or adapting the definition of “Done” if appropriate and not in conflict with product or organizational standards.”

The Sprint Retrospective - What It Is and Tips for Making the Most of Your Meeting: “The focus is on how the team worked together in the last sprint, including: Communication Teamwork Process Tools Systems Work environment Missing competencies Collaboration with external parties”

The practices that might help the Product Owner minimize waste in developing and sustaining the Product Backlog are:

Remove items from the Product Backlog that have not been addressed in a long time. This helps keep the Product Backlog relevant, concise, and focused on delivering value. Items that have not been addressed in a long time may indicate that they are not important, feasible, or desirable anymore. They may also clutter or confuse the Product Backlog and make it harder to order and prioritize.

Only fully describe Product Backlog items when it seems likely they will be implemented. This helps avoid spending too much time or effort on items that may change or be discarded later. Items that are likely to be implemented soon should have more detail and precision than items that are further away or uncertain. The level of detail and precision required for each item depends on its order, size, and complexity.

Other options, such as avoiding distracting the Scrum Team by maintaining newly gathered Product Backlog items in a separate Product Backlog until they are fully understood or handing off ownership of the Product Backlog to someone else, are not practices that might help minimize waste in developing and sustaining the Product Backlog. They may actually create more waste by reducing transparency, collaboration, alignment, or ownership.
