Complete PSM-I Scrum Materials

According to the Scrum Guide, Scrum is a framework to generate value through adaptive solutions for complex problems. It is based on empiricism, self-organization, and collaboration. The other options are not accurate descriptions of Scrum, as they are either too rigid (such as a defined and predictive process or a complete methodology), too vague (such as a cookbook), or irrelevant (such as scientific management).

According to the Scrum Guide, a Developer becomes accountable for the value of a Product Backlog item selected for the Sprint at the Sprint Planning event. This is when the Developers select items from the Product Backlog that they can commit to complete within a Sprint. The Developers are then responsible for creating a valuable Increment that meets the Definition of Done and the Sprint Goal. The other options are not valid, as they either imply that Developers are not accountable for value (such as never or whenever), or that they become accountable at a different time (such as during the Daily Scrum).

According to the Scrum Guide, a Scrum Team is cross-functional if it includes skilled individuals who together have all the skills necessary to create value each Sprint. This means that the Developers can work on any aspect of the product without depending on others outside the team. The other options are not valid descriptions of cross-functionality, as they either imply that the Developers work in silos or rely on external people (such as business analysts, architects, testers, or separate teams).

According to the Scrum Guide 1 , 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. The Sprint Retrospective occurs after the Sprint Review and prior to the next Sprint Planning. The purpose of the Sprint Retrospective is to plan ways to increase quality and effectiveness. The Product Owner is part of the Scrum Team and should participate as a Scrum Team member in the Sprint Retrospective.
