Sharing a resource like an API between projects to leverage each project ' s strengths and reduce duplicated efforts is a risk-sharing strategy. CompTIA Project+ outlines risk-sharing as a way to capitalize on opportunities or mitigate project constraints.

The correct step is to establish communication channels that ensure proper flow of information from idea origination through review and approval. Kickoff meetings occur later, while RACI matrices and stakeholder identification are planning tools — not communication flow structures.

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.

A change log is a document that records and tracks the changes that are made to the project scope, schedule, budget, or quality. It helps the project manager to monitor and control the project performance and ensure that the changes are aligned with the project objectives and stakeholders’ expectations. A change log can also include information such as the change description, impact, status, approval, and date. A change log is the best source for the PM to use to confirm the assertion that the functionality request was rejected during the planning phase, as it would show the details and reasons for the rejection12.

The technical lead should follow the escalation path. The issue described is a performance/response problem that is impacting delivery while the PM is unavailable. CompTIA Project+ emphasizes having and using an escalation path as part of issue management and governance, ensuring problems are raised to the correct authority quickly (e.g., acting PM, functional manager, HR/people manager, or sponsor depending on severity and policy). Escalation is appropriate because the team needs timely intervention to restore progress and accountability.

Updating the issue register (B) is a useful documentation step, but it does not by itself resolve the problem; escalation drives action. Informing all stakeholders (A) is usually excessive and can create noise or reputational harm; stakeholder communication should be controlled and targeted, typically after escalation determines impacts and a recovery approach. Initiating a change request (D) is inappropriate because the core problem is not a requested change to scope or requirements; it is a delivery/behavior issue requiring management intervention.

A good escalation approach is: document facts (missed deliverables, non-responsiveness), attempt direct contact, then escalate per policy to the designated backup PM or functional manager for corrective action (reassign work, coaching, or formal performance steps).

After completing development and internal testing phases, the next step is to conduct User Acceptance Testing (UAT). UAT is performed by the end-users to ensure the system meets their requirements and is ready for deployment.

According to the CompTIA Project+ PK0-005 exam objectives, under Domain 2.3: Explain the importance of quality management and testing in project management, UAT is a critical phase to validate that the product meets the business needs and requirements.

Time and materials contracts are flexible and beneficial when the project scope has many unknowns. They allow costs to be adjusted based on actual time and resources used, which is consistent with CompTIA Project+ recommendations for projects with uncertain requirements.
