Explanation
The next step after defining tasks, durations, resources, and costs is to establish baselines. A baseline is an approved version of a project plan that serves as a reference point for measuring progress and performance throughout the project lifecycle. A baseline typically includes scope, schedule, cost, quality, and risk parameters. Establishing baselines involves presenting the project plan to key stakeholders and obtaining their formal agreement on the project objectives and deliverables. Baseline approval can help to establish clear expectations, avoid scope creep, and facilitate change control during project execution34

When a project team lacks hands-on experience and decides to involve a third-party vendor for product
development, the first document to expedite is a Request for Proposal (RFP). An RFP outlines the project
requirements and asks potential vendors to submit proposals detailing how they would meet those
requirements and at what cost. This allows the project manager to evaluate the capabilities and offerings of
different vendors before making a decision.

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:

This answer is based on the best practice of using historical information and lessons learned from previous projects to improve the planning and execution of current projects12. By using existing artifacts, such as scope statements, project plans, risk registers, and change logs, the PM can leverage the knowledge and experience of the previous PM and avoid repeating the same mistakes or oversights. However, the PM should also accommodate the artifacts based on the current project success criteria, which may differ from the previous project in terms of scope, schedule, budget, quality, or stakeholder expectations34. The PM should not rely solely on the previous PM's advice, the project sponsor's report, or the project charter, as these sources may not provide enough detail or accuracy for the current project's scope statement.

Reviewing the Gantt chart weekly with the team would be the most effective step for the project manager to
take to ensure clarity within the team after receiving feedback from the project sponsor that the resources
involved in the project are unsure of their daily activities. A Gantt chart is a graphical tool that shows the
schedule of a project, including the start and end dates, durations, dependencies, milestones, and progress of
each task or activity. Reviewing the Gantt chart weekly with the team can help to clarify their roles and
responsibilities, assign tasks and deadlines, track and report their status and performance, identify and resolve
any issues or risks, and keep them aligned and engaged with the project goals.VVVVVVVVVVVVVV
