Pollution Control

Correct Answer: Hire a third-party environmental expert to assess the situation, intervene immediately and document the problem in the risk register for further analysis.

The best course of action is to hire a third-party environmental expert to assess the situation, intervene immediately, and document the problem in the risk register for further analysis. This aligns with PMBOK guidelines on risk management, which emphasize identifying, analyzing, and responding to risks promptly. High radioactivity levels pose a serious health and environmental risk that needs to be addressed urgently. The other options are inadequate or inappropriate: - Proceeding with no immediate intervention fails to address a critical risk in a timely manner. - Stopping the project permanently at this stage, before a thorough assessment, is premature and could lead to project failure. - Ignoring the issue prioritizes economic benefits over safety, ethics, and regulatory compliance, which goes against professional standards.

Correct Answer: Statistical Process Control (SPC)

Statistical Process Control (SPC) is the best project management tool to control the issue of exceeding permit limits for particulate emissions during the operational phase of a coal power generation project. SPC uses statistical methods to monitor and control a process, which helps to ensure that the process operates efficiently, producing more specification-conforming products with less waste. In this case, SPC can be used to monitor the emissions and control the process to ensure it does not exceed permit limits. On the other hand, Work Breakdown Structure(WBS) is a key project deliverable that organizes the team's work into manageable sections, Program Evaluation Review Technique (PERT) is a method to analyze the involved tasks in given project to identify the minimum time for completing a task and Cost Variance (CV) is a measure of cost performance on a project. All these tools are important in project management, but they are not the most suitable for controlling emissions in an operational phase of a coal power project.

Correct Answer: Mitigation

In this scenario, the project manager should employ the 'Mitigation' risk response strategy. This is because mitigation seeks to reduce the probability and/or impact of a negative risk or threat. This could include implementing measures to reduce the amount of dust being produced and implementing noise control strategies to limit noise pollution 'Transference' would not be the correct response because this strategy involves shifting the negative impact of a threat, along with ownership of the response, to a third party. However, in this scenario, the project manager cannot transfer the impact of the air and noise pollution to another party 'Exploit' would not be the appropriate strategy because this strategy is used when there are potential opportunities present in a project. Air and noise pollution are negative impacts, not opportunities, thus rendering this strategy unsuitable for this situation 'Avoidance' would not be the appropriate strategy because this mechanism involves changing the project management plan to eliminate the threat or to protect the project objectives from its impact. Here, the construction project cannot be halted completely to avoid the generated disturbances. Thus, the most effective strategy is 'Mitigation'.
