PSPO Changed PSPO-II Questions

The Product Owner is accountable for maintaining and communicating the Product Goal. This responsibility includes ensuring that the goal is visible to everyone and provides direction and purpose for the Scrum Team and its stakeholders

 A burndown chart is a graphical tool that shows the amount of work remaining versus time. It is often used to track the progress of a Sprint or a release. The work remaining is usually measured in terms of effort, such as hours or story points, and it is plotted on the vertical axis. The time is measured in terms of days or weeks, and it is plotted on the horizontal axis. The burndown chart starts with the total amount of work at the beginning of the Sprint or release, and it ideally ends with zero work at the end. The slope of the burndown chart indicates the rate of progress, or the velocity, of the Scrum Team12.

The other options are not what burndown charts track. Accumulated cost, accumulated business value, and individual worker productivity are not relevant or useful metrics for Scrum Teams, as they do not reflect the value or the quality of the product. Scrum Teamsfocus on delivering potentially releasable increments of the product that meet the Definition of Done, and they use empirical feedback to inspect and adapt their work13. References: 1: Understanding and Applying the Scrum Framework 2: Burndown Chart 3: Managing Products with Agility

According to the Scrum Guide, the Developers are accountable for creating a plan for the Sprint, which includes selecting the Product Backlog items that they can deliver in the Sprint1. If they realize that the workload is too high, they have two options: either reduce the scope or increase the capacity. Reducing the scope means removing or changing some of the Product Backlog items, in agreement with the Product Owner, so that theSprint Goal can still be achieved2. Increasing the capacity means adding more Developersto the team, but this is not recommended, as it can disrupt the team dynamics, lower the quality, and increase the communication overhead3. Therefore, the best actions to take are A and B, as they respect the self-organization and collaboration of the Scrum Team, and allow them to deliver a valuable and potentially releasable Increment at the end of the Sprint4.

 A “cone of uncertainty” is a graphical representation of the evolution of the amount of uncertainty during a project. It shows that at the beginning of a project, there is a high degree of variability and unpredictability in the estimates of the scope, cost, time, and value of the product. As the project progresses, more information and feedback are gathered, and the uncertainty decreases, reaching zero when the product is delivered and validated. A “cone of uncertainty” can be used to visualize the uncertainty of the potential value that a Scrum Team delivers over time, and to guide the empirical process of inspection and adaptation. By using a “cone of uncertainty”, a Scrum Team can:

Align the expectations of the stakeholders and customers with the reality of the complex and dynamic environment.

Avoid making premature or unrealistic commitments based on inaccurate or incomplete estimates.

Embrace change and experimentation as opportunities to learn and deliver more value.

Inspect the actual value delivered and the feedback received, and adapt the product vision, strategy, and backlog accordingly.

Forecast the range of possible outcomes and the level of confidence for each Sprint and release.

The other options are not valid uses of a “cone of uncertainty”. A “cone of uncertainty” does not represent the relative level of difficulty for predicting the velocity of individual team members, as velocity is a measure of the amount of work done by the whole Scrum Team, not by individuals. A “cone of uncertainty” does not rapidly identify and prioritize all uncertainties, as uncertainties are not always known or quantifiable, and may change over time. A “cone of uncertainty” does not determine whether to cut quality, similar to the “Iron Triangle” of project management, as quality is not a variable that can be traded off inScrum, but a non-negotiable aspect of the Definition of Done and the value proposition of the product.
