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 creating and communicating a vision, ordering the Product Backlog, and ensuring that the best possible job is done to delight customers. The Product Owner does not manage the Developers, but collaborates with them and the Scrum Master to optimize the value delivery. The Product Owner does not ensure that the work meets the commitments to the stakeholders, but rather that the work delivers value to the stakeholders. The Product Owner does not keep stakeholders from distracting the Developers, but rather engages them and manages their expectations.

[The Product Owner]

In Scrum, the Product Owner is responsible for maximizing the value of the product resulting from the work of the Development Team. One of the primary ways the Product Owner does this is by managing the Product Backlog, which includes clearly expressing Product Backlog items, ordering the items to best achieve goals and missions, and ensuring that the Product Backlog is visible, transparent, and clear to all. This means that the Product Owner has the final authority on the order of items in the Product Backlog, as they are best positioned to understand the strategic and market value of the work to be done.

The Scrum Team membership should change as needed, but not too frequently, as it may affect the team’s ability to deliver value and maintain a high level of collaboration and self-organization. The Scrum Guide states that " Optimal Development Team size is small enough to remain nimble and large enough to complete significant work within a Sprint. Fewer than three Development Team members decrease interaction and results in smaller productivity gains. Having more than nine members requires too much coordination. Large Development Teams generate too much complexity for an empirical process to be useful. " 1 Therefore, the Scrum Team should consider the impact of changing its membership on its productivity and performance, and balance the need for stability and flexibility.

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.

To ensure that the product delivers value, a Scrum Product Owner might focus on the following aspects:

How much of the functionality of the product is being used: This is an indicator of how well the product meets or exceeds the needs and expectations of the customers and users. It can also reveal which features or functions are more or less valuable or useful for them. The Product Owner can use various methods or metrics to measure the usage of the product functionality, such as analytics, user behavior, retention, or engagement.

Direct customer feedback: This is a source of valuable input and insights from the people who use or benefit from the product. It can also help to validate or invalidate assumptions or hypotheses about the product value and quality. The Product Owner can use various methods or channels to collect and incorporate customer feedback, such as surveys, ratings, reviews, interviews, focus groups, or social media.

How quickly or easily the product can be absorbed and used by its customers: This is a measure of how well the product delivers value to customers or users in a timely and convenient manner. It can also affect customer satisfaction and loyalty. The Product Owner can use various methods or metrics to measure the ease of use or adoption of the product, such as time to value, learning curve, usability testing, or net promoter score (NPS).

The other options are not valid or relevant aspects that a Scrum Product Owner might focus on to ensure that the product delivers value. They are either too narrow, unrealistic, or unrelated to the product value delivery. They are:

Velocity is increasing over time: This is not a valid aspect that a Scrum Product Owner might focus on to ensure that the product delivers value. Velocity is a measure of how much work a Scrum Team can deliver in a Sprint. It is not a measure of value or quality. It is also not a goal or target for improvement. It is only a planning tool that helps the Scrum Team forecast their future work based on their past performance. Focusing on increasing velocity over time may lead to unrealistic expectations, pressure, or compromise on quality.

Minimizing changes to project scope: This is not a valid aspect that a Scrum Product Owner might focus on to ensure that the product delivers value. Scrum is an agile framework that embraces change as an opportunity for delivering more value to customers and users. Scrum does not have a fixed project scope, but rather an adaptive Product Backlog that evolves as the product and the market change. The Product Owner should welcome and respond to changes in customer needs and expectations, rather than resist or avoid them.

The Product Owner should not have the entire Product Backlog documented in detail before the first Sprint can start. This is because:

The Product Backlog is an emergent, ordered list of what is needed to improve the product. It is never complete and constantly changes to reflect the needs and desires of the customers, users, and stakeholders.

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 collaborates with the Developers and the stakeholders to refine the Product Backlog as needed to ensure that there are enough items that are sufficiently clear and ready for selection in Sprint Planning. The amount of detail and precision required for each Product Backlog item depends on its order, size, and complexity.

The Product Owner does not need to have the entire Product Backlog documented in detail before the first Sprint can start, as this would imply a fixed and upfront plan that does not allow for feedback, learning, and adaptation. Instead, the Product Owner only needs to have enough items that are well understood and valuable for the Scrum Team to start working on them in the first Sprint.

Scrum

During the Sprint Retrospective, the Scrum Team discusses how the last Sprint went with regards to individuals, interactions, processes, tools, and their Definition of Done123.This includes methods of communication, the way the Scrum Team does Sprint Planning, skills needed to improve the Developers’ ability to deliver, and the Definition of Done123.

The length of a Sprint is the timebox within which the Scrum Team creates a potentially releasable product Increment. The Sprint is a container for all the other Scrum events, such as the Sprint Planning, the Daily Scrum, the Sprint Review, and the Sprint Retrospective. The Sprint is also a feedback loop that allows the Scrum Team and the stakeholders to inspect and adapt the product and the process.

The length of a Sprint should be no more than one calendar month. This is the maximum duration allowed by Scrum, as longer Sprints can increase the complexity and risk of the product development. Longer Sprints can also reduce the agility and responsiveness of the Scrum Team to changing customer needs and market conditions.

The length of a Sprint should also be short enough to keep the business risk acceptable to the Product Owner. 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. The length of a Sprint affects how frequently and effectively the Product Owner can validate, verify, and deliver value to the customers and users.

The length of a Sprint should also be short enough to be able to synchronize the development work with other business events. The Scrum Team operates within a broader organizational context that may have other events, cycles, or deadlines that affect or depend on product development. For example, there may be marketing campaigns, sales promotions, regulatory compliance, or contractual obligations that require coordination and alignment with the product delivery. The length of a Sprint affects how well and timely the Scrum Team can synchronize their work with these other business events.

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

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 Goal. The Sprint Backlog is a highly visible, real-time picture of the work that the Developers plan to accomplish during the Sprint, and it belongs solely to the Developers.

The Developers are accountable for creating a “Done” Increment that meets the Definition of Done each Sprint. The Developers are responsible for planning and executing the Sprint Backlog, designing and building the product functionality, testing and improving the product quality, and delivering a potentially releasable Increment. The Developers work closely with the Product Owner to understand and clarify the Product Backlog items, provide feedback and estimates, and suggest improvements and innovations.

The Developers are also responsible for updating the Sprint Backlog throughout the Sprint. The Sprint Backlog is a plan with enough detail that changes in progress can be understood in the Daily Scrum. The Developers modify the Sprint Backlog throughout the Sprint, and the Sprint Backlog emerges during the Sprint. This emergence occurs as the Developers work through the plan and learn more about the work needed to achieve the Sprint Goal.

As new work is required, the Developers add it to the Sprint Backlog. As work is performed or completed, the estimated remaining work is updated. When elements of the plan are deemed unnecessary, they are removed. Only the Developers can change its content and order during a Sprint.
