The overall goal of selecting strategies during the Plan Risk Response activity is to choose those strategies that have the greatest overall positive influence on the project, considering factors such as cost, schedule, and resources.
According to the PMI Risk Management Professional (PMI-RMP)®Examination Content Outline1, one of the tasks in the domain of Risk Response is to select risk response strategies based on the risk appetite and tolerance of the organization and stakeholders1. The overall goal of selecting risk response strategies is to select the strategies with the greatest overall positive influence on the project objectives, such as scope, schedule, cost, quality, etc. The risk response strategies should aim to enhance the opportunities and reduce the threats to the project, while considering the cost-benefit analysis, the feasibility, and the alignment with the project goals and stakeholder expectations2. The risk response strategies should not be selected based on the least overall impact to resources, because that may not be the most effective or efficient way to address the risks, and it may ignore the potential benefits of some strategies that may require more resources but also deliver more value3. The risk response strategies should not be selected based on the least financial impact, because that may not be the most relevant or comprehensive criterion to evaluate the risks, and it may overlook other aspects of the project, such as quality, customer satisfaction, reputation, etc. that may also be affected by the risks4. The risk response strategies should not be selected based on the greatest benefit to stakeholders, because that may not be the most realistic or achievable goal, and it may create conflicts or trade-offs among different stakeholder groups that may have different or competing interests, needs, and expectations5.

When a risk manager needs to prioritize resources to respond to multiple identified risks, qualitative analysis is the most appropriate tool. Qualitative analysis helps in evaluating the likelihood and impact of each risk using subjective criteria, allowing the risk manager to prioritize which risks require more immediate attention or resources based on their potential impact on the project.
PMI's guidelines on risk management suggest that qualitative analysis is particularly useful in the initial stages of risk assessment, where risks are categorized and ranked based on their severity. This process helps in prioritizing risks that need immediate attention, thus optimizing the use of resources in a project.

The project manager should assess and record associated secondary risks and proceed to treat them as any other risks. This involves identifying and evaluating the potential negative health effects of using pesticides and developing a plan to mitigate these risks. While it is important to consider the concerns of residents, the health authorities have determined that not moving forward with the plan will have more serious consequences on public health.
Secondary risks are those that arise as a direct outcome of implementing a risk response. In this case, the use of pesticides is a risk response to limit the risks of harmful insects, but it may also cause negative health effects to some residents. This is a secondary risk that needs to be assessed and recorded in the risk register, along with its probability, impact, and response plan. The project manager should not suspend the project, as this would ignore the primary risk of harmful insects. The project manager should not consult with health experts to provide a risk trigger, as this is not a valid risk management technique. A risk trigger is an indication that a risk event is about to occur or has occurred, not a condition that prevents a risk response from being implemented. The project manager should not proceed with the project as normal, as this would neglect the secondary risk and its potential consequences. The project manager should follow the risk management process and treat the secondary risk as any other risk in the project. References: PMI. (2017).

Contingency plans are predefined actions that the project team will take if an identified risk event occurs.
They are designed to reduce the impact or probability of the risk, or to restore the project to its original objectives. Contingency plans are part of the risk response planning process, and they should be documented in the risk register. In this case, the risk manager should execute the contingency plans to deal with the delays caused by the weather, as they cannot be avoided or mitigated. Performing time recovery actions, executing prevention plans, or performing change management are not appropriate responses for this risk, as they are either reactive, proactive, or corrective measures that do not address the risk directly.

Risk handling strategies should be reviewed and revised periodically to ensure they remain effective and relevant as the project progresses. This allows the project manager to adapt to changing circumstances and minimize the impact of risks on the project.
According to the PMBOKGuide, risk handling strategies are the specific actions that are taken to implement the risk response plan. The risk response plan is the output of the Plan Risk Responses process, which describes how the project team intends to address the identified risks. The risk handling strategies should be aligned with the risk response strategies, which are the general approaches to deal with the risks, such as avoid, transfer, mitigate, accept, exploit, share, enhance, or accept.
The project manager should work with the risk handling strategies by reviewing and revising them periodically. This is because the project risks are not static, but dynamic and uncertain. They may change over time due to various factors, such as changes in the project scope, schedule, cost, quality, resources, stakeholder expectations, assumptions, constraints, etc. Therefore, the project manager should monitor and control the risk handling strategies to ensure that they are still effective and appropriate for the current risk situation. The project manager should also update the risk register and the risk report with the results of the risk handling strategies, such as the residual risks, secondary risks, and risk triggers.
The other options are not valid for how the project manager should work with the risk handling strategies:
* Implement the strategies after completing the risk analysis: This is not a valid option because the risk analysis is not the final step in the risk management process. The risk analysis is part of the Perform Qualitative Risk Analysis and Perform Quantitative Risk Analysis processes, which come after the Identify Risks process and before the Plan Risk Responses process. The risk analysis helps the project manager to prioritize and evaluate the risks, but it does not provide the specific actions to address them. The risk handling strategies are developed in the Plan Risk Responses process, which comes after the risk analysis.
* Implement the strategies immediately: This is not a valid option because the risk handling strategies should not be implemented without proper planning and approval. The risk handling strategies should be documented in the risk response plan, which should be communicated and approved by the project sponsor, customer, and other relevant stakeholders. The risk handling strategies should also be integrated with the other project management plans, such as the scope, schedule, cost, quality, resource, communication, procurement, and stakeholder management plans. The risk handling strategies should be implemented only when the risk triggers or conditions occur, or when the project manager decides to do so based on the risk analysis and evaluation.
* Ensure the strategies are approved by the stakeholders: This is not a valid option because the approval of the risk handling strategies is not the only thing that the project manager should do with them. The approval of the risk handling strategies is part of the Plan Risk Responses process, which comes before the Implement Risk Responses and Monitor Risks processes. The project manager should also implement, monitor, and control the risk handling strategies to ensure that they are effective and appropriate for the current risk situation.
