Scrum Updated PSPO-I Exam Questions and Answers by myla-rose

 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.

A Product Backlog is:

• Managed by the Product Owner. 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.
• An inventory of things to be done for the Product. The Product Backlog contains all the features, functions, requirements, enhancements, and fixes that constitute the changes to be made to the product in future releases. The Product Backlog items have a description, an order, an estimate, and a value.
• Ordered based on priority, value, dependencies, and risk. The Product Owner orders the Product Backlog items based on various factors that affect their importance and urgency for the product. These may include customer needs, business value, stakeholder feedback, technical dependencies, or market opportunities.

Other options, such as an exhaustive list of upfront approved requirements to be implemented or only visible to the Product Owner and stakeholders, are not valid descriptions of a Product Backlog. They may reflect a misunderstanding of what a Product Backlog is or how Scrum works.

• Scrum is a framework for developing, delivering, and sustaining complex products. Scrum defines three roles: the Product Owner, the Scrum Master, and the Developers. Scrum does not have any other roles or titles, such as “tester”, “analyst”, “designer”, or “architect”.
• 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 Developers are responsible for quality, not just for programming. Quality is not something that can be added or verified after the product is built. Quality is something that must be built into the product from the start, by following good practices, standards, and principles. Quality is also something that must be inspected and adapted continuously, by applying feedback loops, testing methods, and improvement actions.
• The Developers are not divided into sub-teams or sub-roles based on their skills or specialties. The Developers are a cross-functional and self-organizing team that has all the skills and capabilities needed to create a valuable product Increment. The Developers collaborate and coordinate their work as one unit, without any hand-offs or silos.
• The Developers may have different backgrounds or expertise, such as testing, analysis, design, or architecture. However, these are not separate roles or responsibilities in Scrum. They are part of the collective accountability and responsibility of the Developers as a whole. The Developers may perform different tasks or activities based on their skills or preferences, but they are all equally responsible for delivering a high-quality product Increment.

• The “cone of uncertainty” is a graphical representation of the degree of uncertainty in a project estimate over time. It shows that the range of possible outcomes is wider at the beginning of the project and narrows down as the project progresses and more information becomes available.
• The “cone of uncertainty” can be used to illustrate that as a project forecast lengthens, it is increasingly less certain. This means that the longer the time horizon for a project, the more variability and risk there is in the estimate. This also implies that shorter iterations and frequent feedback can help reduce uncertainty and improve accuracy.
• The “cone of uncertainty” cannot be used to determine whether to cut quality, similar to the “Iron Triangle” of project management. The “Iron Triangle” is a model that shows the trade-offs between scope, time, and cost in a project. Quality is often considered as a fourth dimension that is affected by these three factors. Cutting quality is not a desirable option for any project, especially for Scrum projects that value delivering high-quality products that meet customer needs.
• The “cone of uncertainty” cannot be used to determine the cost of a project before it begins. The cost of a project depends on many factors, such as the scope, the resources, the complexity, the risks, and the market conditions. The “cone of uncertainty” only shows the range of possible outcomes based on the available information at a given point in time. It does not provide a definitive or accurate estimate of the cost before the project starts.
• The “cone of uncertainty” cannot be used to determine the length of the next Sprint. The length of the next Sprint is determined by the Scrum Team based on their empirical experience and their ability to deliver a potentially releasable Increment of value. The “cone of uncertainty” does not provide any guidance on how long a Sprint should be or how much work can be done in a Sprint.
