Expert Judgment

Correct Answer: Perform Delphi technique with multi-disciplinary subject matter experts.

The best method for obtaining expert inputs in estimating a project completion date is 'Perform Delphi technique with multi-disciplinary subject matter experts'. The Delphi technique includes iterative rounds of discussion and feedback, ensuring that the most comprehensive and accurate estimates are reached. In contrast, 'consult only internal team members' doesn't take advantage of external expertise which might bring new perspectives or have more suitable experience. 'Ask the client for their completion date preference' and 'Refer to original project timelines without consultation' are not suitable because they do not use expert judgment for adjustment and recalibration of the schedule. The client's preference might not be feasible and referring to original timelines without consultation can imply a lack of flexibility and disregard for emerging challenges or opportunities during execution.

Correct Answer: Temporarily involve a subject matter expert (SME) to provide technical guidance.

The best course of action when encountering an unforeseen challenge requiring specialized knowledge in a project is to temporarily involve a subject matter expert (SME) to provide technical guidance. This is because SMEs have specific expertise in their respective fields and can provide deep insight and solutions to mitigate the challenge. On the other hand, proceeding with the project and documenting the challenge as a lesson learned is not an effective method. This doesn't solve the current issue, it merely records it for future reference. Redirecting project resources to acquiring specialized knowledge internally could be costly and time-consuming, and wouldn't guarantee the level of expertise required. Lastly, cutting project scope to avoid dealing with the challenging issue is not a sound solution as it directly impacts the project's deliverables, and may lead to not meeting the clients' needs or expectations.

Correct Answer: The PM should engage knowledgeable individuals or groups to identify and assess potential risks based on their areas of expertise.

The best answer is that the project manager should engage knowledgeable individuals or groups to identify and assess potential risks based on their areas of expertise. Expert judgment is a valuable tool in risk identification. Experts in relevant areas can provide insights into potential risks that the project manager may not be aware of. They can also help assess the likelihood and impact of identified risks. The other answers are less suitable because: - Solely relying on previous projects ignores the unique characteristics and context of the current project, which may introduce new risks. - Considering risks is crucial during project initiation to plan for risk management throughout the project lifecycle. - While client input is valuable, the project manager should seek expertise from a broader range of stakeholders and domain experts to identify a comprehensive set of risks.
