The velocity chart typically shows the amount of work completed over time. If the "Actual Effort" line is
below the "Planned Timeline," it indicates that the project is not progressing as fast as planned, hence it is
behind schedule. This is inferred by comparing the actual work completed against what was scheduled.
References = The answer is based on standard project management practices and the typical interpretation of
velocity charts in project management. For detailed information, please refer to the CompTIA Project+ Study
Guide and other official CompTIA resources.

The project manager should review the communication plan after learning about some communication issues
with different stakeholders and team members. A communication plan is a document that defines and
documents the communication goals, strategies, methods, channels, frequency, roles, and responsibilities for a
project. A communication plan can help to facilitate effective and timely communication among all
stakeholders involved in a project and avoid confusion, misunderstanding, or conflicts.

SaaS (Software as a Service) provides customers with access to applications over the internet, typically through a web browser. This cloud model allows users to access software without managing the underlying infrastructure. This aligns with CompTIA Project+ guidance on cloud service models for project delivery.

Releasing the project resources is the process of formally ending the involvement of the project team members
and other resources in the project. It also involves updating the resource availability and performance records,
and providing feedback and recognition to the resources. Releasing the project resources is an important part
of the project closure phase, and it helps to avoid unnecessary costs and conflicts. If the project manager
neglects to release the project resources, the team members may still charge time to the project and be unable
to work on new projects12.
