Explanation
The dependency between software installation and desktop installation is a mandatory dependency. A mandatory dependency is a type of dependency that is inherent in the nature or logic of the work and cannot be avoided or changed. It is also known as a hard dependency or a hard logic dependency. A mandatory dependency means that one task must be completed before another task can start or finish. For example, software installation can only start after desktop installation is finished5 The dependency between desktop installation and software installation represents a mandatory dependency. A mandatory dependency is a type of task dependency that is inherent in the nature of the work being performed.
In this case, software installation cannot begin until desktops are installed and powered on, and therefore, the dependency is mandatory.

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.

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 ask the developer to create a change request, which is a formal document that describes the proposed change, its benefits, costs, risks, and impacts on the project scope, schedule, budget, and quality. A change request is the first step in the change control process, which involves evaluating, approving, or rejecting changes to the project baselines. The project manager should not do nothing, because ignoring the recommendation could result in poor performance and customer dissatisfaction. The project manager should not ask the developer to implement the recommendation without following the change control process, because that could cause scope creep, which is the uncontrolled expansion of the project scope without proper authorization or adjustment of the project resources and objectives. The project manager should not communicate the change status before the change request is submitted and approved, because that could create confusion and false expectations among the project stakeholders.

The Project Gantt chart is a scheduling tool used to track task progress and timelines. When tasks are completed ahead of schedule, updating the Gantt chart ensures accurate tracking. This aligns with CompTIA Project+ recommendations on project scheduling and monitoring.

This is compromising because the PM negotiates a middle-ground solution: the end users reduce/simplify what they originally wanted, and the project can implement a version of the change without increasing the constrained budget. Compromising is characterized by each side giving up something to reach an agreement that is acceptable and achievable within constraints (scope/cost/time). This matches Project+ objectives that include applying appropriate communication and people-management techniques (including handling disagreements and stakeholder expectations) to keep delivery feasible.
It is not collaborating, which aims for a true win-win by addressing root needs and often requires more time or resources (for example, securing more budget, changing constraints, or redesigning to meet all requirements).
It is not smoothing (downplaying differences and emphasizing agreement) because the PM is actively changing the request content to fit constraints. It is not avoiding, because the PM is directly engaging and resolving the conflict rather than postponing or sidestepping it.
So the PM used compromising to maintain stakeholder buy-in while protecting the budget constraint and still achieving an implementable change outcome.
