Explanation:
Schedule variance is calculated as EV -PV, or $1,500 -$1,200 = +$300. Because the SV is positive, physical progress is being accomplished at a faster rate than planned.

Explanation:
During the adjourning stage of team development, the emphasis is on tasks and relationships that promote closure and celebration. There is recognition and satisfaction as the theme is moving on and separation. Management skills involve evaluating, reviewing,
and improving, while leadership qualities are celebrating and bringing closure.

Explanation:
The review at the end of a project phase is called a phase-end review. The purpose of this review is to determine whether the project should continue to the next phase for detecting and correcting errors while they are still manageable and for ensuring that the
project remains focused on the business need it was undertaken to address.

Explanation:
The monitor and control project work process is performed throughout the project and includes collecting, measuring, and disseminating performance information and assessing measurements and trends to effect process improvement. Continuous monitoring is
important because it provides insight into the project’s health, highlighting areas requiring special attention.

Explanation:
The tools used from plan quality management and control quality are used in perform quality assurance. The perform quality assurance process also uses affinity diagrams, process decision program charts, interrelationship digraphs, tree diagrams, prioritization
matrices, activity network diagrams, matrix diagrams, quality audits, and process analysis.

Explanation:
Prototypes are used to obtain early feedback on requirements by providing a working model of the expected product before it is built. Stakeholders then can experiment with this model rather than discussing abstract representations of requirements. This
approach supports progressive elaboration, because it is used in iterative cycles of mock-up creation, user experimentation, feedback generation, and prototype revision.

Explanation:
Project assumptions, which should be enumerated in the project scope baseline in the scope statement, are areas of uncertainty, and therefore, potential causes of project risk.

Explanation:
Cost of quality involves both the cost of conformance and the cost of non-conformance. Examples of the cost of conformance are divided into two categories prevention costs and appraisal cots (includes inspections). Costs of non-conformance include internal
failure costs and external failure costs.

Explanation:
Organizations that rely on products for their revenue must constantly be introducing new products into the marketplace as old products are removed. Ideally, this should be an overlapping process to maintain balanced or increasing revenue over time. The closure
phase evaluates the efforts of the total system and serves as input to the conceptual phase for new projects and systems. It also has an impact on other ongoing projects with regard to identifying priorities.

Explanation:
Validate scope focuses on accepting project deliverables, and to be accepted, they must meet the requirements. Control quality is one way to ensure that the requirements have been met, which is why control quality typically is done before validate scope.
