Free Practice Questions for Scrum PSPO-I Exam

 A Scrum Team is required to deliver a done Increment by the end of a Sprint. Done means:

No work is left to meet the Definition of Done. The Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product. It is a shared understanding among the Scrum Team and the stakeholders of what it means for work to be complete. It may include criteria such as coding standards, testing, documentation, security, performance, etc. If a Product Backlog item or an Increment does not meet the Definition of Done, it cannot be released or presented at the Sprint Review.

Ready to be released to end users. The Increment is a concrete output of the Sprint that adds value to the product. It is a potentially releasable functionality that adheres to the Scrum Team’s current Definition of Done. It is not necessarily released at the end of each Sprint, but it must be in a state that allows for immediate release if the Product Owner decides so. The Increment should also align with the Sprint Goal and the Product Goal, and satisfy the needs and expectations of the customers and stakeholders.

If the Developers find out during the Sprint that they are not likely to build everything they forecast, the best response from the Product Owner is to re-work the selected Product Backlog items with the Developers to meet the Sprint Goal. This is because:

The Sprint Goal is a short-term objective that provides guidance and focus to the Scrum Team throughout the Sprint. It is a flexible and negotiable commitment that can be adjusted as more is learned throughout the Sprint.

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 Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. They must inspect the Increment at the end of each Sprint and assess how it delivers value and contributes to the Product Goal.

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.

If the Developers find out during the Sprint that they are not likely to build everything they forecast, it means that there is a gap between their initial plan and their actual progress. This may happen due to various reasons, such as new insights, changing requirements, technical challenges, or unforeseen circumstances.

In this situation, the Product Owner should work with the Developers to re-work the selected Product Backlog items to meet the Sprint Goal. This may involve adding, removing, or modifying some items, as long as they still support the Sprint Goal and deliver value. The Product Owner should also communicate any changes or impacts to the stakeholders and customers as appropriate.

Other options, such as skipping Product Backlog refinement activities, informing management that more Developers are needed, changing the Sprint Goal, or canceling the Sprint, are not valid responses from the Product Owner as they do not reflect what should happen in Scrum or how to deal with uncertainty and complexity.

Multiple Scrum Teams working on the same product do not have to have the same Sprint start date. The Scrum Guide does not prescribe any synchronization of Sprints across multiple teams1. However, it is recommended that the teams align their Sprint cadence and duration, and coordinate their dependencies and integration through a shared Product Backlog, a common Definition of Done, and frequent communication2. This way, the teams can deliver a coherent and valuable product Increment every Sprint[3][3].

The Developers are the people in the Scrum Team who 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 Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product. The Definition of Done is used to assess when work is complete on the product Increment.

The amount of work required of the Developers to complete a Product Backlog item selected during the Sprint Planning depends on the Definition of Done. The Definition of Done may vary from one Scrum Team to another, depending on the context and domain of work. However, it must be consistent within one team. If there are multiple Scrum Teams working on one product, they must share a common Definition of Done. If there is an organizational standard for a Definition of Done, all Scrum Teams must follow it as a minimum.

The Developers must ensure that each Product Backlog item they complete during a Sprint meets the Definition of Done. This means that they must perform all the necessary tasks and activities to deliver a high-quality product functionality that is usable, valuable, and potentially releasable. This may include analysis, design, development, testing, documentation, integration, deployment, or any other aspects that contribute to the quality and usability of the product.

The other options are not valid or relevant measures for the amount of work required of the Developers to complete a Product Backlog item. They are either too vague, arbitrary, or unrealistic. They are:

As much as they can fit into the Sprint, with remaining work deferred to the next Sprint: This is a too vague and unrealistic measure for the amount of work required of the Developers. It does not account for the quality or value of the product functionality delivered. It also does not respect the timebox or scope of the Sprint. It may lead to incomplete or unfinished work, technical debt, or scope creep.

All development work and at least some testing: This is a too arbitrary and insufficient measure for the amount of work required of the Developers. It does not account for the quality or value of the product functionality delivered. It also does not respect the Definition of Done or the potentially releasable nature of the Increment. It may lead to low-quality or unusable work, defects, or rework.

A proportional amount of time on analysis, design, development, and testing: This is a too restrictive and prescriptive measure for the amount of work required of the Developers. It does not account for the complexity or variability of the product functionality delivered. It also does not respect the self-organization or cross-functionality of the Developers. It may lead to over-engineering or waste.

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 approach for Scrum Teams to produce valuable Increments is to be accountable for developing functionality from beginning to end, as this enables them to deliver potentially releasable products that meet the definition of “Done”. The Scrum Guide states that "The Developers are the people in the Scrum Team that are committed to creating any aspect of a usable Increment each Sprint."1 This means that the Developers are not limited by the boundaries of components, layers, or technologies, but rather they collaborate and coordinate to deliver a complete and integrated product that satisfies the Sprint Goal and the Product Owner’s expectations.

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 Product Backlog is an ordered list of everything that is known to be needed in the product. It 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.

All types of requirements are acceptable on a Product Backlog, as long as they are aligned with the product vision and goals, and they are transparent, clear, and valuable. The Product Backlog can include stability requirements, performance requirements, product functionality, documentation, fixes, or any other aspects that contribute to the quality and usability of the product.

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 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.

Scrum is a framework that is designed to be lightweight and easy to adopt. To get started with Scrum, the minimal requirements are indeed a Product Owner with enough ideas for a first Sprint, a Development Team to implement those ideas, and a Scrum Master to facilitate and guide the process. This aligns with the core principles of Scrum, which emphasize self-organization, collaboration, and the ability to deliver increments of value quickly and frequently.

References: The Scrum Guide outlines the roles within a Scrum Team and the necessity of having a Product Backlog with enough ‘Ready’ items to fill a Sprint. The guide also emphasizes the importance of having a clear definition of ‘Done’ before starting the first Sprint
