The project manager can use the burn up chart to analyze the current status of the project based on its scope (value delivered), budget (cost), and schedule (time). A burn up chart is a graphical tool that shows how much work has been completed (burned up) versus how much work remains (scope) over time. It also shows how much budget has been spent (burned up) versus how much budget remains (budget) over time. A burn up chart can help to monitor and control the project progress and performance and identify any variances or deviations from the plan. The chart given shows that both scope and budget lines are above their respective target lines at any given time point. This means that less work has been completed than planned (scope variance) and more money has been spent than planned (budget variance) at any given time point. Therefore, the project is behind schedule and over budget.

A rollback plan is used when an issue is identified during testing or implementation. It allows the team to revert to the previous state, removing the new package. This aligns with CompTIA Project+ guidance on implementing fallback strategies for risk management.

Smoothing is a conflict resolution technique that involves minimizing or ignoring the differences between the parties and focusing on the common interests or goals1. It is often used when the conflict is not very important or when there is a need to maintain harmony and relationships2. By using smoothing, the project manager can reduce the tension and stress caused by the disagreement and encourage the team members to cooperate and work together. Smoothing is different from compromising, which involves finding a middle ground or a trade-off that partially satisfies both parties; forcing, which involves imposing one's own solution or decision on the other party; and collaborating, which involves finding a win-win solution that fully satisfies both parties3.

Quantitative KPIs are measurable and based on numerical data. The statement about task completion time being 25% faster is quantitative, as it involves specific data that can be measured and tracked, as recommended by CompTIA Project+ for project performance evaluation.

The program manager should first obtain details from the owner of the project that is causing the delay, such as the root cause, the impact, the mitigation plan, and the revised timeline. This will help the program manager to assess the situation, communicate with the stakeholders, and adjust the program schedule accordingly. Updating the critical path, applying contingency reserves, and reestimating epic user stories are possible actions that the program manager may take after obtaining the details, depending on the severity and duration of the delay. However, they are not the immediate next steps, as they require more information and analysis. References = CompTIA Project+ Study Guide: Exam PK0-005, Third Edition, Chapter 10:
